Open source

Independent tools that work well together.

We publish the infrastructure we actually use. Each project is useful on its own. Client work reuses the same foundation — we only build the part specific to your business.

Our client work starts with the same open-source tools we build for ourselves. That means less time rebuilding infrastructure and more time solving the part specific to your business.

  1. We build open-source infrastructure
  2. We use it ourselves
  3. Client projects reuse the same foundation
  4. We only build the parts specific to your business

Builder and Doctor

Existing skills and MCP configs become a portable Agent Plugin, then get validated. The collection is the real output of that chain.

  1. Existing setup / skills / MCP
  2. Agent Plugins Builder
  3. Portable plugin
  4. Agent Plugins Doctor
  5. Validated / diagnosed plugin

What we believe

Secondary to the projects themselves.

  • AI-native interfaces

    REST, SDK, CLI and MCP where they belong — agents should be able to use the same tools people do.

  • Self-hosting

    Run on infrastructure you control. Your data does not have to leave your environment.

  • Portability

    Plugins and skills should move between compatible clients instead of being rewritten for each one.

  • Composability

    Independent tools that work well together. Nothing here requires adopting a HiAI framework.

  • Simple infrastructure

    Postgres, Redis and S3-compatible storage. No mystery platform underneath.

  • Reproducible development

    Declarative configs, checks and licenses you can audit.

  • Permissive OSS

    MIT or Apache-2.0. Use the tools on their own, or with the rest of the set.
