Quick answer: Use automatic crash capture so you see stack traces without asking, fix the highest-occurrence crash first, automate player acknowledgement, and pace yourself. As a solo dev, you survive launch-day crashes by leaning on tooling to do the work you cannot do alone.
When you are a solo developer, launch-day crashes land entirely on you, no QA team, no on-call rotation, no one to split shifts with. A wave of crashes on hardware you never tested can feel impossible to handle alone. The way through is to let tooling carry the load that a team would otherwise share: automatic crash capture, occurrence-based prioritization, and automated player communication, so your scarce human hours go entirely to fixing.
Let Crash Capture Replace the QA Team
Without a team, you cannot manually reproduce crashes across dozens of player configurations, so the crashes have to report themselves. Automatic crash capture that attaches the stack trace, device context, and recent logs gives you what a QA team would have gathered, without you doing the gathering. A solo dev with good crash capture sees more than a small team without it.
Bugnet's crash reporting attaches a stack trace and device context to each crash and groups identical crashes by signature, so instead of fielding a hundred 'it crashed' messages, you see a handful of distinct crashes ranked by how many players hit each. That grouping does the triage a teammate would otherwise help with.
Fix the Highest-Occurrence Crash First
Alone and under pressure, you can only fix one thing at a time, so the order has to be right. The crash with the highest occurrence count is hitting the most players and generating the most refunds and reviews, fix it first, ship it, then move to the next. Occurrence counts make this prioritization objective, so you are not guessing which crash matters most while exhausted.
Each crash you fix and ship reduces the incoming volume, which clears your dashboard and your head. As a solo dev, this compounding relief is essential: the first fix makes the second easier to see, and the flood becomes a list.
Automate Communication and Pace Yourself
You cannot personally reply to every report and also fix crashes, so automate the acknowledgement, every reporter gets an instant receipt while you stay heads-down on fixes. Post a known-issues update so the community sees you are on it without you answering each message individually. Automated communication buys you the focus a solo dev cannot otherwise afford.
Most importantly, pace yourself. You are the only person who can support this game, not just today but for months, and an exhausted solo dev makes mistakes that create more crashes. Fix the top crashes, set automatic acknowledgements to cover you while you rest, and resist the all-nighter. Surviving launch as a solo dev means still being able to function tomorrow.
Solo at launch, your tooling is your team. Let it capture and rank the crashes so your hours go to fixing.
