Agentsmith
Open Source Prompt CMS
A couple weeks back I remembered one of the golden rules of startups... to JUST LAUNCH.
So I stopped being a pussy and launched it. It will never be perfect, I have a ton of changes and features I want to add, but you know what they say: "if you're not embarrassed by the first version of your product, then you've launched too late".
🚀 just launched https://t.co/eEJEQsyFUX, an open source Prompt CMS!
- author prompts with jinja syntax
- editor auto-extracts typed variables
- built on top of @OpenRouterAI , easily test any LLM
- syncs prompt templates to a PR in your GitHub repo
- syncs both ways, push… pic.twitter.com/wEvpPHElJ7— Chad $yntax (@chad_syntax) July 29, 2025
About
While building my first startup, I ran into a lot of friction keeping things in sync between non-technical prompt authors and engineers. I built Agentsmith to streamline the entire prompt engineering process.
