Tools that make development feel clear, calm, and complete.

Sylin

Tools that answer to you.

An independent software toolworks: developer frameworks, home-lab infrastructure, and tools for AI agents. All of it local-first, running on your hardware, still working when the internet doesn't.

Flagships

  • Koan, the stack. One grammar, Entity<T>, covers CRUD, REST, vector search, jobs, caching, and agent (MCP) tools, then tells you exactly what it wired up. Rails for .NET, shaped for development where coding agents write much of the code. .NET 10.  v0.17 · pre-1.0
  • Koi, the network. A LAN toolbox: discover services, name them, trust them, serve them, all from one cross-platform binary with no accounts and no cloud. Label a container and the whole pipeline runs. Rust.  v0.9.0
  • Ghostlight, the guardian. Let an AI agent drive your real browser, logins, tabs, and sessions included, governed when you want it and wide open when you don't. Works from any MCP client. The engine is open source; organizations pay only for governance, never for autonomy.  v0.5.4 · open-core
  • Zen Garden, the estate. Turn the laptops and thin clients headed for landfill into self-hosted infrastructure that survives a machine dying: ask for services by type, never by hostname. Rust.  v0.2.0 · active

Also in the works

  • Growing: Agyo, PowerToys for Koan (opt-in libraries one layer above the framework, never below)  ·  os-tools, one symmetric Rust API over each OS's native machinery, starting with installing a CA into the system trust store everywhere.
  • Research: Hokora, a cognitive architecture for artificial companions drawn from neuroscience rather than retrieval  ·  Nagi, a breathing companion you hold, not watch.

How Sylin works

  • Local-first. Your hardware, your network. No accounts, no telemetry, no cloud in the critical path.
  • Open at the core. The engines are open source and free to run. Where there's a paid layer, it governs how a tool is used; it never gates your ability to run it.
  • Candid. Every project publishes its decision records, a maturity label, and a "when not to use this." Pre-1.0 is stated wherever it's true.

Get involved

Issues and discussions are welcome on any repo. Most projects are pre-1.0 and moving fast; check the maturity label before you build on one.
