Both tools capture browser traffic to reverse-engineer APIs. The difference: DataFaucet outputs a hosted MCP server your AI agents can call immediately. Kampala outputs raw API specs and replay scripts you wire up yourself.
| Capability | DataFaucet | Kampala |
|---|---|---|
| Primary purpose | ✓Generate hosted MCP servers from any web app | ~Reverse-engineer websites/apps into raw API specs |
| Output format | ✓Hosted MCP server (SSE endpoint, ready to connect) | ~API export (OpenAPI spec, replay scripts) |
| MCP compatibility | ✓Native (standard MCP protocol, any client) | ✗No MCP output (requires additional tooling) |
| Hosting included | ✓Yes (one-click deploy, managed endpoint) | ✗No (local tool, self-host any output) |
| Traffic capture | ✓Cloud browser with proxy layer | ✓Local MITM proxy (desktop app) |
| Auth chain tracing | ~Captures authenticated session cookies/tokens | ✓Full auth chain tracing with fingerprint preservation |
| Mobile app support | ~Web apps only (browser-based) | ✓Web + mobile + desktop apps |
| Platform support | ✓Any OS (web-based, nothing to install) | ~Mac only (Windows waitlist) |
| Setup time | ✓60 seconds (paste URL, interact, deploy) | ~5-10 minutes (install app, configure proxy, capture) |
| AI agent integration | ✓Immediate (Claude, Cursor, Windsurf, Codex) | ✗Manual (export API, build integration yourself) |
| Flow replay/export | ~Via MCP tool calls (stateless) | ✓Full flow replay with fingerprint spoofing |
| Pricing | ✓Free tier (3 servers), paid for more | ~Early access (pricing TBD) |
Need your AI agent to call the API, not just document it?
DataFaucet deploys a live endpoint. No export-then-build step.
Kampala (by Zatanna AI, YC W26) is a local MITM proxy that intercepts traffic from any app on your machine. It traces authentication chains, preserves browser fingerprints, and exports the captured API interactions as replayable scripts or OpenAPI specs. Powerful for security research, reverse engineering, and building scrapers.
DataFaucet captures traffic through a cloud browser and goes one step further: it deploys a hosted MCP server from the captured calls. Your AI tools connect to it immediately without any intermediate build step. The output speaks standard MCP protocol, so Claude, Cursor, Windsurf, and Codex can call it out of the box.
If your goal is to understand and replicate an API, Kampala is a deep tool for that. If your goal is to give AI agents access to a web app's functionality right now, DataFaucet closes the gap between capture and usage.
