developer tools.
small utilities we built for ourselves and released free. json, tokens, cron, licenses, logs, env checks — the boring scripts we kept losing the links to.
no ads, no tracking, no paywall. available on GitHub and npm. use them, fork them, submit patches.
jsonyo
format and query json without leaking your payloads.
it is a json formatter that does not steal your data.
tokcount
count tokens and estimate llm api costs offline.
it counts tokens so you do not bankrupt yourself on api calls.
ctxstuff
dump your codebase into a single file for llm context.
it turns your repo into a giant string you can paste into chat interfaces.
promptdiff
compare llm outputs with a side-by-side diff.
it is a diff tool for hallucinating language models.
httpwut
catch and inspect webhooks without deploying code.
it is a bucket that catches incoming http requests so you can see what is in them.
gitstats
analyze git repository history locally.
it tells you who wrote the most code and which files change too often.
licenseme
generate open-source license files in three seconds.
it generates the legal text you need to open-source your side project.
envguard
validate your environment variables before your app crashes.
it stops your app from booting if you forgot to set a database url.
depcheck
find and remove dead dependencies from your project.
it tells you which packages you can delete to make your build faster.
logparse
turn messy text logs into structured json.
it turns your unreadable server logs into json so you can actually query them.
cronwtf
translate cron expressions into human language.
it tells you when your cron job is actually going to run.
randumb
generate structured random data for testing.
it spits out fake user data so you can test your database.
these will stay free forever. we use them too.
