Error Tracking SaaS for Game Studios
Publish the Crash Post-Mortems Your Steam-Shipping Competitors Hide Behind NDAs
Synthesised by Generated by Diffmode's 576-vector synthesis engine · Last updated
Stuck at $3.1K MRR, third Monday staring at the same Stripe number. Your last 14 customers came from /r/gamedev comments — not Sentry's blog. Publish the autopsies they cannot.
The short version
-
Point your own error-tracker at a public Steam game every Monday and post the de-mangled IL2CPP stack trace as journalism — not a demo.
-
End every post with paste your trace below and I'll walk through it; the DMs become trial signups your existing /r/gamedev motion can't reach.
-
12-month moat: Sentry and Bugsnag's enterprise customers have anti-disclosure clauses. Only an indie-tier vendor with an indie-tier game's permission can publish raw traces.

The Public Crash Autopsy Series
How to publish what Sentry's enterprise customers' lawyers won't let them post — and convert /r/unrealengine DMs into 14-day trials
Every Monday, you point your own error-tracker at a public game — week one, an open-source Unity roguelite on GitHub. Week two, your own demo title. Week three, a friendly studio's game with explicit publish permission. The product captures real IL2CPP-de-mangled crashes, GPU driver context, the exact scene that triggered the regression. You write a 500–700 word post-mortem in the structure indie gamedevs already screenshot to teammates: symptom → de-mangled trace → root cause → one-line fix. The product appears only in the screenshots, as the dashboard the reader can see in the background. Diffmode surfaces this pair — your own product pointed at a public game (the dogfooding side) plus a question-funnel artifact the audience already shares peer-to-peer — as one angle that fits your fingerprint.
The distribution loop is the close. Every post ends with paste your trace below and I'll walk through it. The comment thread becomes lead capture. The DMs that follow — can you look at our build's crash log? — become 14-day trial signups. Sentry, Bugsnag, and Backtrace cannot copy this format because their enterprise customers have anti-disclosure clauses; their legal teams kill the post on contact. Only an indie-tier vendor with an indie-tier game's permission can publish raw traces, and only one whose product actually de-mangles IL2CPP and parses Switch crash dumps will produce posts that don't read as laughable to a Unity engineer reading them at 11pm.
Diffmode's pSEO walks you through the four uncovered surfaces (/r/unrealengine, /r/godot, TIGSource, GameDev.tv #crash-help) the founder-input flagged as blind spots. Three Mondays in, the comment threads tell you what to write next — the second-most-asked question becomes Week 4's post. No coding. No agency. The math closes at 16 post-mortems × ~1,500 views × the 1–2.5% click band × 15–22% trial conversion on warmed Reddit traffic × your existing 9.8% trial-to-paid rate — 3 to 14 paying studios in Month 1, $345–$1,610 of new MRR against your current $3.1K. Kill criterion: under 0.5% click-through across four posts means the lede reads as a vendor pitch — rewrite in the voice of five top-upvoted /r/gamedev crash threads from the last 60 days (https://www.reddit.com/r/gamedev/).
Expected Results
3–14 paying studios in Month 1
By Month 3 the question funnel produces 1–3 paid customers/month from this channel alone — Month 1 is for seeding the four uncovered subreddits, not closing. Implied MRR range: $345–$1,610 at the $115 weighted ARPU across Solo/Studio/Pro plans.
Budget Required
<$1K — effectively $0/month direct
Reddit free, GameDev.tv and Unreal Source Discord free, the product itself is your own SaaS at zero marginal cost. Optional: CleanShot X $29 one-time for screenshot annotation, Loom free tier for 60-second walkthroughs, Plausible already in your stack.
Time to Signal
Day 5
By end of Week 1: 8+ profile clicks on ~1,500 post views (the 1–2.5% r1 band), 3+ DM conversations started from the paste your trace below CTA, and at least 1 DM where you suggested the 14-day trial at the end of a free walkthrough.
Why this combination wins
- Stuck at $3.1K MRR with one working channel (/r/gamedev comments). The founder needs a second motion that uses the product's only real moat — de-mangling IL2CPP and parsing Switch crash dumps — without buying ads against Sentry.
- Dogfooding alone becomes a brag-blog. A question funnel alone becomes Stack Overflow. The pair turns each post-mortem into proprietary evidence AND a DM-capture surface — the dashboard sits in every screenshot.
Tools You'll Need
| Tool | Purpose | Cost | Setup |
|---|---|---|---|
| Your own error-tracker (dogfooded against a public game) | Captures, de-mangles, and visualizes the real crash data that becomes each post-mortem's evidence base | Free (you own it) | 0 minutes (already configured) |
| Reddit (account ≥6 months old, ≥500 karma) | Publication surface for /r/gamedev, /r/unrealengine, /r/godot, /r/Unity3D, and TIGSource cross-posts | Free | 10 minutes per subreddit to read the sidebar rules |
| GameDev.tv Discord + Unreal Source Discord | Secondary distribution to engaged engineers — the #crash-help and #troubleshooting channels are the natural home for post-mortem links | Free | 15 minutes (verify role, read pinned messages) |
| CleanShot X (or built-in macOS screenshot + annotation) | Captures and annotates stack-trace screenshots so the evidence reads cleanly on Reddit's image preview | $29 one-time (CleanShot) or free (built-in) | 5 minutes |
| Loom (free tier) | Records a 60-second walkthrough of the de-mangled stack trace for posts that need motion to land the moat | Free (25 videos / 5 min each) | 5 minutes |
| Plausible (or your existing analytics) | Tracks per-post UTM-tagged clicks from the Reddit bio link to landing page and trial conversion attribution | Already in stack | 10 minutes to add 4 UTM-tagged variants |
Week 1: Day-by-Day Plan
Pick a public game and run your error-tracker against it
- Pick the source game for Week 1's post-mortem — an open-source Unity or Godot title on GitHub with >100 stars and known crash reports in Issues. Document the repo URL and the 2–3 crash issues you'll target.
- Build the game locally and point your own SaaS at it. If Unity, confirm IL2CPP de-mangling is active — this is the moat that has to show up in the screenshots.
- Reproduce one documented crash and capture three CleanShot screenshots: player-side symptom, de-mangled stack trace from the dashboard, and the source file with the offending line highlighted.
- Open a Google Doc titled Week 1 Post-Mortem: [Game Name] and paste the three screenshots in. No copy yet.
Three annotated screenshots of a real, reproducible crash from a public game sit in a doc with no writing yet.
Write the post-mortem
- Write 500–700 words in this exact structure: two-sentence symptom hook → player-side screenshot → here's what the de-mangled trace says → the line of code that's wrong → one-line fix → close with paste your trace below and I'll walk through it.
- Keep voice raw and casual. No product names in the body. The product appears only in the screenshots, as the dashboard in the background.
- Update your Reddit profile bio to one low-key line: I build [product name] — error tracking that actually understands IL2CPP. Comments here are help, not pitch.
A 500–700 word draft with three embedded screenshots, the paste your trace below CTA, and the updated Reddit bio.
First publish + first Discord drop
- Post the Week 1 post-mortem to /r/unrealengine, /r/godot, or /r/Unity3D — pick a subreddit you haven't covered. Tuesday or Wednesday 8–10am US Central is the peak gamedev-on-Reddit window.
- Drop the link in the GameDev.tv Discord #crash-help channel (or the Unreal Source equivalent) with one sentence: Wrote up a [Game Name] crash I reproduced this week — full de-mangled trace and the fix.
- Sit at the post for 4 hours. Reply to every comment within 30 minutes — answers, not pitches. Walk through every DM'd stack trace using the SaaS, capture each thread in a sheet (handle, question, trial-suggested Y/N).
Post live on a new subreddit, link in Discord, all Day-3 comments and DMs replied to within 30 minutes for the first 4 hours, sheet has at least 1 row.
Follow-ups and Week 2 source-game pick
- Read every new comment and reply to every DM. Note which questions repeat — they become Week 2's topic.
- If anyone DMs can you look at our crash log?, walk through it with your SaaS and reply with screenshots. Suggest the 14-day trial only at the end of a useful walkthrough — never at the start.
- Pick Week 2's source game (ideally your own demo title or a friendly studio's title with explicit publish permission). Email or DM the friendly studio today.
- Schedule a Friday cross-post to /r/gamedev with a rewritten lede acknowledging the original sub.
Every Day-3 comment and DM has a reply, Week 2's source game is identified with permission secured or pending, the /r/gamedev cross-post is scheduled.
Measure, decide, write Week 2 draft
- Pull the metrics — total views (Reddit shows this after 24h), upvotes, comments, DMs, profile-clicks (Reddit insights + your UTM-tagged bio link in Plausible), trial signups attributable to the post.
- Compare against the early-signal band: 0.5% click-through is the kill threshold. With ~1,500 expected views, kill is <8 clicks in 7 days.
- If pass: write Week 2's post-mortem using the question that came up most. If fail: read five top-upvoted /r/gamedev crash threads from the last 60 days and rewrite the lede in their voice — republish to a different sub on Day 8.
- Update the sheet with Week 1 totals and any trial-to-paid conversions during the week (your existing 9.8% rate means 1–2 paid is the optimistic outcome from Week 1 alone).
Week 1 metrics recorded, kill-criteria check logged, Week 2 source game and topic committed.

The Crash Post-Mortem Post (Reddit + Discord)
Publishing the weekly post-mortem to /r/unrealengine, /r/godot, /r/gamedev, /r/Unity3D, or TIGSource. Same skeleton works in Discord drops — strip the title and the closing CTA, keep the three screenshots.Title: [Game Name] crashed every 6th run on Steam — here's the stack trace and the one-line fix Was reproducing [GAME_NAME]'s issue #[ISSUE_NUMBER] this week and the symptom was the kind of thing every indie hits: random crash, no repro steps, players posting screenshots of the stack trace to the Steam reviews. [SCREENSHOT 1: the player-side symptom or the Steam review with stack trace] The stack trace itself looked like this once it was de-mangled (IL2CPP makes you work for it): [SCREENSHOT 2: the de-mangled stack trace from the dashboard] The actual culprit was a [SPECIFIC_TECHNICAL_CAUSE — e.g., "null component reference inside an OnCollisionEnter that only fires when two pickups overlap on the same frame"]. Here's the line: [SCREENSHOT 3: the source file with the offending line highlighted] Fix is a one-line null check before the dereference: if ([VARIABLE] == null) return; Pushed the fix to my fork and the crash is gone. Repro steps and the patched build are in the linked thread on GitHub: [GITHUB_LINK_TO_PR_OR_ISSUE_COMMENT] If you've got a stack trace you can't pin down — Unity, Unreal, Godot, doesn't matter — paste it below and I'll walk through it. Happy to spend 20 minutes on a real one.
The DM Reply (Stack-Trace Walkthrough)
When a reader DMs you a stack trace from their own game asking for help. This is the conversion surface — but the FIRST message is 100% help, 0% pitch. The trial mention belongs in your THIRD message at earliest, and only if the walkthrough surfaced something they want to keep doing.Hey — thanks for sending this over. Looking at the trace, the line that matters is [LINE 3 or 4 of the stack], specifically [SPECIFIC_FUNCTION_OR_VARIABLE]. That tells me the crash is happening in [SUBSYSTEM — e.g., "the GC compaction phase right after a scene unload"] rather than in your gameplay code, which is why it's been hard to repro locally. Two quick questions before I can be more specific: 1. What engine version are you on? ([UNITY_VERSION] / [UNREAL_VERSION]) 2. Does the crash happen on the same scene/level every time, or does it move around? If you can grab a second crash dump that includes the GPU driver version, that usually narrows it to a 5-line code path. Reply here or screenshot the dashboard view and I'll keep going. — [FOUNDER_FIRST_NAME]
Week 1 Checkpoint
By end of Week 1 you should have shipped the first post-mortem on a new subreddit and seen the early-signal band fire — or not.
- ✓1 post-mortem published on a new subreddit (/r/unrealengine, /r/godot, /r/Unity3D, or TIGSource), cross-posted to /r/gamedev on Day 4–5, dropped in 1 Discord
- ✓8+ profile/link clicks within 7 days of publish (the 1–2.5% r1 band on ~1,500 views — below this is the pivot signal)
- ✓3+ DM conversations started from the paste your trace below CTA, with at least 1 conversation ending with you suggesting the 14-day trial
- ✓1 source game and 1 topic committed for Week 2's post-mortem, with permission secured or pending if it's a friendly studio's title
When to pivot
If Week 1's post has <0.5% click-through (fewer than 8 profile/link clicks on ~1,500 views) AND zero DMs after 7 days, the lede is reading as a vendor pitch. Rewrite in the voice of five top-upvoted /r/gamedev crash posts before publishing Week 2.
Weeks 2+: Scaling Schedule
| Week | Focus | Tasks | Time |
|---|---|---|---|
| Week 2 | Repeat the loop with a friendly studio's game (or your own demo title) | Publish Week 2's post-mortem (topic chosen from Week 1 comments; source game has explicit publish-permission), Add /r/godot or TIGSource as the second new subreddit if Week 1 covered /r/unrealengine — round-robin across the three uncovered subs from your founder-input, Reply within 30 minutes to every comment and DM for the first 6 hours after publish; continue daily replies for 5 days | 8–10 hours total |
Read before you ship
Caveats
This tactic assumes you have 8–10 hours/week of weekend availability for the off-hours posting and the 30-minute DM-reply discipline across the first 4 hours after publish. If your day-job spikes or a console cert window eats the weekend, the loop dies before Week 2 — the post-mortem cadence is the asset, not any individual post. Your founder-input ruled out hiring a marketing agency ($5K/mo is 1.6× your current MRR and no agency understands IL2CPP), LinkedIn outbound (tested 6 weeks, 1 reply out of 80), Google Ads (burned $240 in 3 weeks against Sentry's enterprise pockets), and a founder podcast tour (the gamedev podcast surface is fragmented across 30 micro-shows you don't have booking relationships for). All four constraints survive into this play.
The permission step is load-bearing. Week 1 is safe — open-source games on GitHub with public issue trackers are fair game. Week 3 and beyond require explicit publish permission from a friendly studio whose crash you're going to autopsy with their name attached. Email or DM the friendly studio in Day 4 of Week 1 at the latest; if permission isn't cleared by Sunday, fall back to your own demo title for Week 2 and re-ask. Skipping the permission step is the fastest way to torch a relationship with the indie studios who are your warmest leads.
The $400/month marketing budget cap holds. Reddit and Discord are free; the only material spend is the optional $29 one-time CleanShot X license. Do not buy a sponsored newsletter slot or a /r/gamedev award until the trial-to-paid signal closes — the first $180 sponsored newsletter you ran produced 6 trials and 1 customer, which is positive but slow, and the budget belongs to Month 2's scaling, not Month 1's seeding.
Closest analogue
Case study: Josef Strzibny's Deployment from Scratch — the Ruby-on-Rails solo author whose long-form Linux dogfooding compounded into a one-Hacker-News-post breakout
Josef Strzibny shipped Deployment from Scratch as a solo full-stack engineer who'd quit a small-startup dev-lead role and needed something that paid before it scaled. The fingerprint is the same as yours — capitalIntensity low, 95%+ gross margin on a digital download, repeat-purchase low but ARPU bumped by a Rails-SaaS-starter follow-on, localVsNational global, channel access full but reflexively distrustful of LinkedIn polish. He chose the book topic on credentials, not appetite: he'd been a Linux packager at Red Hat, so he combined Linux fundamentals with deployment because no existing book covered tool-free deployment as a teaching artifact. The early phase was slow on purpose — the first 100 mailing-list subscribers took 159 days, the next 100 took 334 days, and the channel was his developer blog with a 350-unique-visitor monthly baseline and a corner-image link to the book's landing page.
The break came from one Hacker News post that crested 300+ upvotes and sold 100 copies in a single day — the highest revenue day of his life at that point. The mechanism is the same as the public-crash-autopsy tactic: a single piece of long-form technical content (his book chapters, your post-mortems) lands on a community where the content itself is the moat (deep Linux internals; de-mangled IL2CPP traces), the audience is engineers who reflexively distrust vendor polish, and one focused channel beats a six-tactic dabble. He grossed $40K+ on Gumroad across the book and his Business Class Rails-SaaS starter, best month $8,930 in December 2021 sales.
The founder-seat parallel is load-bearing. He didn't pre-validate, didn't run paid acquisition, didn't hire help. He published technical credentials in a format the audience already screenshotted to teammates, kept a public mailing list, and let the long-form posts back-fill SEO from his blog. The plateau he had to break was the same one you're staring at — a single-channel founder with a credibility moat (Red Hat packaging; IL2CPP de-mangling) waiting for one focused asset to land in front of the right community. The lesson: credentials-based topic selection beats appetite-based selection at this stage. You are not running content marketing; you are publishing forensic evidence.
Failure modes
Anti-patterns
Do not run cold email at 1K/day volumes — your LinkedIn experiment already documented the failure mode (1 reply per 80 messages over 6 weeks), and game-studio buyers are even more allergic to inbound DMs than the average B2B engineer. Do not buy Google Ads on crash reporting unity or sentry alternative game — the $240 burned in 3 weeks against Sentry's enterprise pockets is the kill signal; the keyword pool is too small to outbid enterprise CPC.
Do not publish a post-mortem against a closed-source commercial game without explicit publish permission. One cease-and-desist on a /r/gamedev post will torch the channel — indie subreddits read every vendor-vs-studio dispute as evidence the vendor is the problem. The permission step in Day 4 of Week 1 is non-negotiable.
Do not lead the DM walkthrough with the trial offer. The first message is 100% help and 0% pitch; the trial mention belongs in your THIRD message at earliest, and only after the walkthrough surfaced something the reader wants to keep doing. Leading with the trial converts the DM thread from a moat-demo into a sales call, and the audience scrolls past sales calls.
Do not let the Twitter/X bug-thread one-off bias the format. The 11K-impression Mono GC thread that converted 1 customer was a one-off, not a repeatable post-mortem format. The dashboard had to be on screen; the trace had to be de-mangled; the post had to end with a question funnel. Without all three, the format collapses to a brag-blog within two weeks.
Do not stop the existing /r/gamedev answer-mining motion. It produced 14 of 27 customers and is the only channel with repeatable conversion. The autopsy series sits on top of it for the four uncovered surfaces; it does not replace the working channel.
