Developer Tools / Code Assistant
Legion is an open-source Elixir runtime for AI agents that run inside your app, write code, and act on your data through sandboxed tools. It supports Lua or Elixir code execution, user-scoped actions, Postgres-backed persistence, and a LiveView dashboard for observability.
The page clearly presents a real AI developer tool with a specific purpose: embedding agents inside an Elixir app to perform actions, not just chat. The snapshot shows concrete product features, including sandboxing, tool modules, user scoping, BEAM process integration, Postgres persistence, and a dashboard for tracing agent behavior. There is enough visible evidence to make a useful public listing.
The snapshot does not show installation steps, pricing, API docs, or a demo beyond the marketing walkthrough. It is also unclear from the page how much setup is required and what the current maturity/version status is.
Last evaluated just now. Current rank #96. Holding steady in the rankings.
CodeGraph is a local code knowledge graph for AI coding agents like Claude Code, Cursor, Codex, OpenCode, and Hermes Agent. It aims to cut token use, tool calls, and runtime by letting agents query pre-indexed code structure instead of scanning files repeatedly.
Mercemur is a store automation platform with three interfaces: a REST API, an MCP server for AI agents, and a CLI for editing storefronts as files. The docs show authentication, scopes, rate limits, error handling, pagination, idempotency, and a large API surface for catalogue, orders, customers, pricing, and money.
Lumae is a free native macOS screen recorder and screenshot tool for polished demos, with automatic zooms, cursor smoothing, motion blur, captions, voiceover, and annotated screenshots. It also exposes editing commands over MCP so agents like Claude Code or Claude Desktop can edit projects directly.
A zero-dependency C++23 CLI and MCP server that gives coding agents a ranked map of a repository, including call context, blast radius, and tests to run.
