Neo

Turn any web app into an API. No official API needed. No browser automation.

Neo is a Chrome extension that passively captures every API call your browser makes, learns the patterns, and lets AI (or you) replay them directly.

The Problem

AI agents operating web apps today have two options, both bad:

| Approach | Pain | |----------|------| | Official APIs | Most SaaS doesn't have one, or only exposes 10% of features | | Browser automation | Screenshot → OCR → click. Slow, fragile, breaks on every UI change |

Neo is the third way. Every web app already has a complete internal API — the frontend calls it every time you click something. Neo captures those calls and makes them replayable.

v2: Now with UI automation. Neo v2 adds an accessibility-tree-based UI layer — snapshot, click, fill, type, press, hover, scroll, select, screenshot, get, wait. When an API exists, use it directly. When it doesn't, Neo can drive the UI through the same CLI. One tool, both layers.

How It Works

Browse normally → Neo records all API traffic → Schema auto-generated → AI replays APIs directly
                                                                      → Or drives UI via a11y tree

1. Capture (always-on)

The Chrome extension intercepts every fetch() and XMLHttpRequest — URLs, headers, request/response bodies, timing, even which DOM element triggered the call.

2. Learn

Run neo-schema on a domain to auto-generate its API map: endpoints, required auth headers, query parameters, response structure, error codes.
