EvalGlass Core · the open product in the family
What EvalGlass is, and what it isn't
EvalGlass Core is the open-source, local product you can install today: evaluations derived from your own system — code, schemas, prompts, traces — and owned as code in your repo, your AI’s real spec. In plain terms, it is an AI quality-control tool that lets your coding agent build and run project-specific checks for your app. Knowing what it deliberately is not is part of the product: the honest boundary is what keeps a scorecard worth reading.
It is / it is not
| EvalGlass Core is | EvalGlass Core is not |
|---|---|
| A local-first, open-source AI quality-control tool (EvalGlass Core) you operate through your coding agent. | A hosted platform, dashboard, or telemetry product. |
| A way to build project-specific checks from your repo, traces, prompts, and model calls. | A generic benchmark suite or a leaderboard. |
| A producer of bounded scorecards with honest verdicts: informational, pass, fail, blocked. | A certification, or a universal trust score, that your AI is correct, safe, or production-ready. |
| A tool that fits the stack you already run — repo, CI, traces. | A broad GRC replacement, or a required central trace warehouse. |
| Repo-native: your project keeps the truth and the authority to gate. | Something that grants gate/approve/certify authority by itself. |
| Led by the Claude Code plugin, with Codex supported as a second runtime. | Tied to a single coding-agent runtime. |
"Local-first" describes Core. The wider family is not necessarily local-only: Discovery and Intelligence can be customer-invoked and run privately — in your own environment or a managed private deployment. Adopting either never changes Core's licence or its local independence.
The ground-truth floor
We state the project's real status plainly wherever it matters. EvalGlass is
v0.2.1 pre-alpha, tagged, and not yet on PyPI. It is
Apache-2.0 and local-first: it runs on your machine and in CI, sends no telemetry,
needs no provider keys on the run path, has no hosted platform,
and ships with empty authority by default — a fresh install gates nothing. There
is no gate, approve, or certify verb.
