Apache-2.0, and free in the way that matters

The license

EvalGlass is released under the Apache License 2.0. You can use it commercially, modify it, vendor it into your own repo, and ship products built around it — without asking permission and without paying for a seat.

Apache-2.0 also carries an explicit patent grant: contributors license the patents that read on their contributions, so adopting EvalGlass does not quietly expose you to patent claims from the people who wrote it.

Three honest "no"s

EvalGlass is pre-alpha and local-first. Because it runs entirely on your machine and in your CI, there is simply no place to insert a meter. These are not promises we are choosing to keep — they are properties of how the tool is built.

• No platform to pay for. There is no hosted EvalGlass, no dashboard service, no SaaS. Evaluation happens in your repo, against your evidence.
• No API keys to buy. The required path needs no provider SDKs and no model keys. Live models are an optional, opt-in lane you own — not a toll on the core.
• No telemetry leaving your repo. EvalGlass collects nothing and sends nothing. Your datasets, traces, and scorecards stay where you put them.

Local-first means there is no cost centre to monetise. That is why the project can be free without a catch hiding behind it.

If money ever enters the picture

EvalGlass is at version 0.1.0 with no tagged releases yet, and no funding channel is wired. We would rather say that plainly than imply a maturity the project does not have.

If paid support or services ever exist, they will be clearly separate, clearly optional, and never a gate on the tool itself. The core stays Apache-2.0. How the project sustains itself →

There is nothing to sign up for. Install the plugin, point your agent at a repo, and let it vendor the source.
