Halfhand — Replay Every Action Your Agents Took

This site was found by StackScope Discovery, our own first-party launch detection. The tech stack below comes from that discovery scan; the full analysis (screenshots, scores, page checks) is added when the site is picked up by a launch platform.

Halfhand is a local-first developer tool for recording, replaying, and debugging AI agent execution. Inspect prompts, tool calls, MCP traffic, file modifications, and execution history through a deterministic replay interface.

Own this Launch?

StackScope records what new websites are built with, the week they launch. Most we find ourselves, by watching public internet infrastructure for brand-new sites; the rest come from Product Hunt, Hacker News and PeerPush. We crawled this one to detect its tech stack. This page is what we saw on 6 August 2026; the live site may have changed since.

Every technology below links to its own page: which other new sites launched with it. Vendors and agencies watch those pages with Stackdar and hear about new adopters the week they ship, from £15 a month.
