I built Cendor: open-source production plumbing for LLM applications

After sixteen years of building enterprise systems, I released my first open-source project.

It is called Cendor, and it is production plumbing for LLM applications: seven small libraries and an SDK that control cost, block unsafe inputs, and keep an audit trail under any agent framework. Python and TypeScript, Apache-2.0, free.

This blog stays on its Microsoft-stack beat, so I am keeping the announcement short. Cendor has a home of its own now, and it is described far better there than I could repeat here.

Where everything lives

• The full announcement: cendor.ai/blog/introducing-cendor
• The site and docs, one page per library: cendor.ai
• Run it keyless in your browser: cendor.ai/try
• The code: github.com/cendorhq
• The LinkedIn page: linkedin.com/company/cendorhq

One rule I set for the project: honest claims. Every public number on the site is benchmark-backed and regenerates offline, and the limits are published beside the numbers. Cendor is open source under Apache-2.0, non-commercial and local-first. If you build something with it, or find a claim I cannot back, I want to hear about it.
