Raintree Technology builds reliable AI products and open-source developer tools.
Built for humans. Ready for agents.
- DocPull — Turns changing websites into cited, reproducible context that agents can verify before they act.
- PolicyStrata — Catches policy drift before release by turning cross-layer failures into deterministic, reproducible tests.
- HIG Doctor — Checks Apple-platform code against the HIG and cross-platform code against aligned accessibility and interface-quality rules.
- Trellis — Catches risky shortcuts, security footguns, and structural debt with shared Biome checks and deterministic JSON fix lists.
- Raintree Standards — Defines testable requirements, evidence, task profiles, and exceptions for Raintree product and agent work. Pre-1.0.
- SimpleOS — Experimental Unix-like 32-bit x86 operating system built from scratch in C and assembly that boots and runs in a browser.
- BetterOff — Brings spending, investments, assets, debts, and net worth into one view so people can see where they stand and what to do next.
We build with source-linked context, scoped permissions, deterministic tests, human approval, and reproducible evidence.
