Mason Code is an independent project: a native AI coding IDE and the cloud gateway that powers it — for developers who want strong models without enterprise pricing.
A native macOS coding agent: chat with your codebase, ranked whole-repo search, checkpoints to undo agent edits, built-in terminal and browser, project rules via MASON.md. BYOK, local Ollama — or Mason Cloud.
One OpenAI-compatible endpoint in front of a curated lineup of the strongest, best-value coding models. Flat plans, live budgets, crypto payments. Works in any tool with a custom provider.
A mason builds things that last, brick by brick — like the agent: small, verified changes with checkpoints so nothing is ever lost.
Local-first where possible, transparent budgets, no lock-in: your keys work everywhere, your code stays yours, the gateway logs usage — not prompts.
Mason Code started as a terminal experiment — a CLI agent with pluggable providers. It grew into a full IDE, then into infrastructure: if the agent runs best on affordable models, why not make those easy for everyone to buy?
That's Mason Cloud: the same gateway we use ourselves, opened up. One key, flat pricing, every strong model — in our IDE or whatever editor you already love.
