Show HN: Jev-browse, browser sub-tasks for coding agents at ~1/3 the cost
Jev-browse adds typed browser sub-tasks to browser-harness, letting agents like Claude Code or Codex hand off a whole website task in one call. Each step uses the small TypeSafe Jev model, which answers in a few hundred milliseconds, and the tool reports 1.6-3.0x faster and 2.1-5.3x cheaper runs than having the agent drive the browser directly, with the same pass rate. It is an MIT-licensed port of browser-use/jev-ultrafast.
- for who
- Developers using Claude Code or Codex for agentic browser workflows.
- why now
- New Jev-browse API cuts coding agent browser costs by 3x, now available.
- what changes
- Browser sub-tasks become one-call hand-offs, cutting model turns and costs while keeping the same pass rate.
- to do
- Install jev-browse from github.com/danielnc/jev-browse, run its installer, store the TypeSafe API key in the browser-harness .env, and add the pointer to your agent's global instructions.
key points
- Jev-browse adds fast_run to browser-harness, letting agents offload website sub-tasks in one call
- Each decision is a TypeSafe Jev request, a few hundred milliseconds, no screenshots or large model
- Form and navigation tasks ran 1.6-3.0x faster and 2.1-5.3x cheaper with same pass rate
