Launching something custom? Here is the stack-agnostic checklist.
The categories that matter do not change based on your framework. The specific implementation does.
Whatever you built it in, the categories that decide whether a launch survives its first month are the same: authentication, secrets management, backups, rate limiting, payment webhook verification, error monitoring, HTTPS, input validation, access control, and dependency hygiene. The specific implementation of each varies by stack, but skipping the category does not.
This page exists for anyone whose stack is not one of the named ones above, Rails, Django, Laravel, a custom Go or Rust backend, or anything else. The Launch Checklist tool below filters to universal items only when no specific stack is selected, which is exactly the right default for an unlisted stack.
What gets missed on Custom / other stack apps.
The opposite is often true. Purpose-built stacks skip fewer things by default, but nothing forces the review pass that catches what is still missing.
Every item on the universal checklist needs to be verified against your actual implementation rather than a stack-specific "here is exactly where to click."
Common questions.
My stack is not listed. What should I check?
The ten universal categories: authentication, secrets management, backups, rate limiting, payment webhooks, error monitoring, HTTPS/HSTS, input validation, access control, and dependency hygiene. The Launch Checklist tool below defaults to exactly this list when no specific stack is selected.
