Jet Browser packages WPE WebKit and a Rust WebDriver bridge as a standalone runtime. One container runs one isolated browser session; your harness sends ordered JSONL commands and receives machine-readable results.
Bring any harness or deterministic test runner. No account, API key, model, database, or hosted control plane is required.

Pick Jet Browser when
Jet Browser is the execution layer for runs that need a clear, inspectable browser boundary:
- Isolation matters: one disposable browser session per container, with explicit lifecycle and resource limits.
- Evidence must agree: native input, DOM state, and a fresh screenshot come from the same runtime instead of separate replay paths.
- The harness should stay replaceable: ordered JSONL works with any model, agent loop, CI job, or deterministic test runner.
- You need a non-Chromium runtime: WPE WebKit provides a second engine without shipping another browser-agent framework.
Keep Playwright, CDP, or your current browser stack when you need their browser matrix, extension ecosystem, or an existing signed-in Chrome profile. Jet Browser does not attach to daily Chrome and does not include a model or agent.
