Small things that answer one question and get out of the way — some we built, some we tested. The ones we built run entirely in your browser: nothing to install, no account, no upload.

Paste any repository and see when it last shipped: last commit, last release, and whether the owner has archived it.
Star counts only ever go up — they record how popular a project once was, not whether anyone still maintains it. Plenty of 40k-star projects have not tagged a release in over a year.

Search every free tier we have verified — what you get, whether a card is required, and the date we last confirmed it.

Say what you are hosting, whether it may sleep, and whether you have a card. Get the two or three free hosts that fit.
Each pick comes with its catch up front: the idle pause, the card check, the non-commercial clause. Hosts whose free tier is gone are listed too, so you stop looking for them.

A throwaway inbox you never signed up for — for testing signup flows without burning a real address.
Which ones expose a usable API, and how to pull a magic link out of a real inbox from a Playwright test.

A phone number you can receive a verification code on, in 180+ countries, without owning a SIM there.
What it costs, which services it has numbers for, and the three API calls that get you a number and poll it for the code.
