Sustainability
There is no product to sell you.
This is the honest version of a pricing page. EvalGlass is open source, local-first, and pre-alpha — there is no product to buy and no SaaS to subscribe to. The tool stays free; the one paid path is hands-on help from the makers, and that is what keeps it free.
Where it stands today
EvalGlass is pre-alpha software at version 0.1.0, with no tagged releases yet. It is maintained by Syntelesis-Lab and licensed under Apache-2.0.
There is no product revenue and no sponsorship channel wired up: no FUNDING.yml, no GitHub Sponsors, no paid product, and no SaaS. EvalGlass collects no telemetry, runs no hosted platform, and asks for no provider keys. The tool itself bills nobody for anything — the only way the work is funded is hands-on help from the makers, below.
Why local-first lowers the bar
EvalGlass runs on your machine and in your CI. There are no servers to keep running on the project's behalf.
That is a deliberate design choice, not a cost-saving accident. Because nothing is hosted, the project needs no recurring revenue just to stay online. A tool that runs entirely from vendored source in your repo does not switch off when a bill goes unpaid — it keeps working as long as your machine and your CI do.
If you want it built around your stack
EvalGlass is built by Syntelesis-Lab, a multi-agent AI-safety lab — the same people who care that an evaluation never claims more than it measured. The tool stays free and open. But if your team wants hands-on help, the makers are open to custom work: bespoke evaluators, adapting EvalGlass to your own systems, or standing up an honest evaluation setup for your AI application.
This is the honest answer to so how does it get funded? — work like this is what keeps the core free and Apache-2.0. There is no price list and no obligation; if it would help, start a conversation.
Possible future funding
None of the options below is active. Each is a direction the project could take later, marked honestly so it is never mistaken for something available now.
- GitHub Sponsors. A way to support maintenance directly. Possible, not yet active — there is no sponsor button.
- Ongoing support contracts. A standing arrangement beyond the one-off custom work above. Possible, not yet active.
Whatever happens, the core stays Apache-2.0 and stays runnable with the plugin and the maintainers gone. There is no paywall on trust-critical features. Honest measurement is the whole point of the project; it cannot sit behind a subscription.
This is the most honest a pricing page can be.
There is no product to buy and no price list. The one thing on offer is the makers' time — never the tool itself, which stays Apache-2.0 and free. The remaining funding options are possible, not yet active. When that changes, this page changes.
