Why open source
Zeldoc.ai is built on open source, and our documentation focuses on open source tools. This isn't an accident — it's a deliberate choice rooted in trust.
You can verify how it works
When you use an AI coding agent, you're giving it access to your codebase, your terminal, and your shell. That's a lot of trust. With closed source tools, you have no way to know exactly what the agent does with that access — what data it collects, where it sends it, or what it injects into your prompts.
Open source removes that risk. You can read every line of code, audit it yourself, and verify that the tool does what it claims — nothing more, nothing less. There are no hidden behaviors, no secret data collection, no buried telemetry that you can't inspect.
Why our docs focus on open source
We document open source agent harnesses because we believe you should be able to trust the tools you use. When we recommend a tool, we want to be able to point at the source code and say: this is exactly what it does.
This is also why we recommend OpenCode — it's fully open source and you can audit it yourself.
Why we don't recommend Claude Code
We're often asked why we don't recommend Claude Code — after all, it works with Zeldoc.ai just fine. The answer isn't about capability. It's about trust.
Claude Code is closed source. You can't see what it does under the hood, what data it collects from your environment, or what it injects into your prompts. When a coding agent has access to your repository and your shell, that's a risk we're not comfortable asking you to take. Open source tools don't have that problem — if you ever wonder what's happening, you can just read the code.
That said, Zeldoc.ai works with any tool that supports a custom base URL. If you choose to use Claude Code or another closed source tool, you can find the connection details on Use Zeldoc.ai with any AI tool. We just won't document it as a recommended path.
Zeldoc.ai works with any open source tool that supports a custom base URL. See Use Zeldoc.ai with any AI tool for details.
