Solarch is open-source now!
Today, we are taking our biggest step yet.
We just open-sourced the Solarch core engine.
Here is what this means for you:
🔥 Bring Your Own Key (BYOK): Don't trust us with your architecture data. Plug in your own API key (DeepSeek, Claude, OpenAI) and run the compiler locally. Zero data leaves your environment. Zero token markups.
🧠 Meet 'Simple Mode': No dev required. We’ve added a clean, visual flowchart view (think Excalidraw vibe) so Founders and PMs can map out pure business logic. Meanwhile, the open-source engine strictly syncs it with production code in the background.
🛡️ Developer-First Model: The core engine is available on GitHub under a PolyForm license. It is completely free for individual builders and indie hackers (Commercial B2B teams can use our fully managed SaaS at app.solarch.dev).
Stop drawing flowcharts on whiteboards that get lost. Design actual systems that compile.
Check out the repo, see the engine in action, and if you believe in deterministic engineering over vibe coding, a GitHub ⭐️ would mean the world to us!

Open-sourcing the core engine is a smart credibility move, especially for a tool people may want to inspect before building around it. One thing that helps adoption a lot is a very clear “first useful contribution” path: small issues, architecture notes, and examples of what a good plugin or extension should look like.
