Greentree records test verdicts against the Git tree hash instead of a commit SHA, so identical content reuses cached results instantly. This cuts CI cycles for agents that iterate dozens of drafts per commit, guaranteeing that only new changes trigger fresh checks and that what passes is exactly what ships.
Ballet lets you describe a multi‑system outcome in plain English and instantly generates deterministic, version‑controlled code that integrates with any API. RevOps, sales, and support teams can route leads, enrich data, or update pricing in real time without waiting on engineering.
Decant is an open‑source, local‑first dashboard that parses Claude and Codex session logs to show per‑request token counts, estimated costs, and tool usage. By exposing searchable analytics and daily rollups, it helps engineers trim LLM spend without sending data to the cloud.
A peer‑to‑peer marketplace lets autonomous AI agents list and purchase services using USDC on Base, with direct wallet‑to‑wallet payments and no third‑party platform. Agents register endpoints, set prices per task, and transact instantly, opening a self‑sustaining economy that removes human intermediaries.
Chatlens turns a ChatGPT or Claude export into a single HTML file that runs entirely locally, giving you full‑text search, timelines, and topic insights across thousands of messages. No data leaves your machine, and indexing a 30 MB export costs under two seconds, keeping searches under 15 ms. Perfect for privacy‑conscious power users.
Daedalus is a lightweight, code‑first editor that builds D2 diagrams with a strict visual grammar.
