About

keelinfra builds open-source tools that keep Jenkins and the machines around it current: Agent8 for Jenkins, which keeps build hosts stuck on Java 8, 11 or 17 connected to a current Jenkins controller, and the Jenkins upgrade matrix, which shows how an old controller gets to the current LTS. (An earlier Keycloak distribution was discontinued in October 2026.)

Deliberately small

keelinfra is not a platform vendor with an account team. It's built by Xianpeng Shen, an engineer based in Lithuania, who builds the tools and publishes every claim with a receipt. When you email hello@keelinfra.io, the person who answers is the person who will do the work. For the buyer we serve, that's not a limitation; it's the point:

• You talk to the engineer, not an account manager.
• Everything is in the open — the code, the CI runs, the claims ledger. At this size there's no process to hide behind, so we don't try.
• We say "you don't need us" when you don't. The tools are complete without a support plan or a service engagement — that's by design.
• If keelinfra stopped tomorrow, nothing you run would stop. The code runs on your own machines, and it is open source down to the build scripts (Agent8), so you can keep it going yourself.

Who builds it

Xianpeng Shen maintains open-source tools for building and shipping software:

• cpp-linter — clang-format and clang-tidy on every pull request. More than 1,000 repositories on GitHub depend on it.
• explain-error-plugin and jenkinsfilelint, in the jenkinsci organization. Agent8 itself is independent and not endorsed by the Jenkins project.
• Years of keeping Jenkins builds working on AIX, written up along the way: from Git clones to IBM Java certificate chains.

The operating principles

1. Tested, not promised. No claim ships without a test behind it: a public CI run, a published measurement, or a drill you can run yourself. Where a platform is tested by hand and not in CI (AIX, Solaris, HP-UX), the page says so.
2. The ops knowledge is the product — and it's open source (Agent8: MIT; jenkins-upgrade-check: Apache-2.0). No open-core split, no gated features, no relicense rug-pull.
3. Your machines, your data. Nothing phones home to us. There is nothing of yours for us to lose.
