What the code does

In the project's build, not in the package

Found in continuous integration, deployment or infrastructure files, or in a neighbouring package of the same monorepo. None of this is installed when you add the server: it describes how the project is built and released. We list it because a leaked key in a build pipeline is still a real problem, but it is not something this server does on your machine.

Touches key and credential files .github/workflows/publish-npm.yml:47
          npmrc="${NPM_CONFIG_USERCONFIG:-$HOME/.npmrc}"

Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.

Nothing serious here today

Today is the operative word: we check Cejel every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

Cejel — questions

Answers built from our own checks of this server.

Why is there no uptime for Cejel?
Cejel runs on your own machine over stdio — there is no network address to reach, so uptime cannot be measured for it by anyone.
Is Cejel open source?
Yes — it is published under the AGPL-3.0 licence, written in TypeScript, 2 stars on GitHub and 51 open issues. The source link is on this page, so you can read exactly what it does with your data before you connect it.
