Jev DevTools

A React / Next.js inspector for TypeSafe Jev that captures systemOne calls, shows returned probabilities, and maps the paths your app takes.

What it is

See the typed decisions your code already makes.

What it does: Mounts a drawer that records Jev requests and branch outcomes in React or Next.js App Router.

Why it belongs in the showcase: First-party-shaped DevTools for hosted Jev flows.

Caveats: Experimental npm package.

Evidence

Public MIT repo, created 2026-10-23, about 6 stars as of 2026-10-26. npm package jev-devtools v0.5.3 (experimental). Docs at docs.jevtools.dev and site jevtools.dev (HTTP 200). Uses @typesafe-ai/sdk 0.7.x; API key stays on the server; capture is opt-in and off by default. CI badge on main.

Caveats

  • APIs remain experimental before 1.0
  • Intended for development capture, not a production control plane
  • Needs a server adapter shared by handlers and the drawer
