Open source

Open by default, where we can be.

Some of Tillio runs as a hosted product. Other parts — the templates, the SDK, the ledger primitives — make more sense in the open. Here's what's out, what's coming, and how to contribute.

Released

MIT

Equity agreement templates

The plain-English vesting and milestone templates that ship with the product. MIT-licensed, fork-friendly.

Released

Apache 2.0

Tillio SDK (TypeScript)

A typed client for logging contributions, reading the ledger, and triggering payouts from your own tooling.

In progress

Q3

Ledger primitives

The double-entry contribution ledger as a standalone library — useful even if you don't run Tillio.

In progress

Q3

Category weight rubrics

The starter weights and override patterns we observe across project shapes, published as a living document.

Considering

Evaluation engine adapters

Pluggable scoring backends so teams can swap model providers without rewriting their pipeline.

How to contribute

Patches welcome.

Open an issue, send a PR, or just file a thoughtful bug report. Our contributing guide explains the review cadence and what we look for in changes.

Substantive PRs are logged on the contributor's Tillio ledger where applicable — you don't have to use the product to contribute, but it's a nice loop.
