Prime Agent is an MIT-licensed open-source coding and research agent from Prime Intellect, built around a Recursive Language Model (RLM) runtime and a persistent IPython control environment. The model works through programmatic Python: file/shell operations, data transforms, skills, context management, and recursive subagents are all callable from the durable kernel rather than exposed as a large fixed tool palette.

Matched agent

Local-first AI agent whose control loop and all state run on the machine. Drives browser, files, approved shell, documents, memory across sessions, scheduled tasks, and MCP tools. Default path is llama.cpp (their TurboQuant fork) so small quantized models stay useful for long multi-step work on consumer hardware.

Matched agent

Gives agents structured desktop accessibility reads and actions through a CLI, C library and MCP server.

Matched agent

An MCP server using Playwright to let AI models visually analyze, automate, test, and debug web interfaces.

Matched agent

Agentation is a visual feedback layer for agents working on web UIs. Humans click elements, annotate, optionally use layout mode (rearrange/resize), then copy structured markdown (or push via MCP/webhooks) so the agent gets element paths, CSS selectors, positions, and related context instead of vague prose.

Matched agent

Deep Agents (langchain-ai/deepagents) is LangChain AI’s batteries-included agent harness: production-ready, extensible, with filesystem, context management, sub-agent delegation, skills, and long-term memory (PyPI summary). README principles: opinionated, extensible, model-agnostic, production-ready on LangGraph + LangSmith.

Matched agent

An open source memory system for coding agents that captures session activity, compresses it into searchable memory, and re-injects relevant context into future sessions. The repo positions it as agent-agnostic infrastructure that can work across Claude Code, OpenClaw, Codex CLI, Cursor, Gemini CLI, and other MCP or HTTP-capable agents.

Matched agent

Sitegeist is an AI assistant that lives in a Chromium side panel, plus a bridge so coding agents can use the same browser. README framing: collaboration over “autonomy theater” — you guide, it executes. Automates repetitive web tasks, extraction, navigation, forms, research → docs/spreadsheets; BYO API key or subscription login (Anthropic, OpenAI/ChatGPT, GitHub Copilot, Gemini, etc.); claims local-only / no tracking.

Matched agent

Vellum Assistant is a personal AI assistant product (OSS + managed cloud) in the same broad class as Hermes / OpenClaw / NanoClaw: multi-channel agent, skills, memory, computer use, OAuth-connected tools, managed or self-hosted runtime. Entry capture was the OAuth Integrations key-concept doc: browser OAuth2 instead of pasting API keys; each integration is a bundled skill with tools (e.g.

Matched agent

Human-in-the-loop training data, RL environments, and evaluation for AI agents and LLMs.

Matched agent

bb is an MIT-licensed, self-hosted agentic IDE that coordinates installed coding-agent CLIs in persistent, steerable threads. Its first-class control surfaces are a desktop app, web app, CLI, and HTTP API. The project’s central differentiator is that much of its UI/workflow surface is implemented as plugins, so an agent can extend the IDE itself rather than only working inside a fixed product.

Matched agent

Box is a managed sandbox product from Ascii (legal entity Dedale AI, Corp.). It sells persistent Linux VMs for coding agents and agent platforms: SSH, Docker inside the VM, a dedicated IPv4 per machine, snapshot/stop/resume, fork-from-snapshot, optional 60fps desktop stream, and a CLI/API/box prompt path for Claude Code or Codex.

Matched agent

Developer interfaces for speech generation, transcription, audio and voice-agent workflows.

Matched agent

fx is a Vercel Labs coding-agent harness and CLI written in Zig. Official copy positions it as a tiny, open, native agent originally used internally, now open sourced for research and embedding in larger systems. The durable object is the product at fx.sh / vercel-labs/fx, not the tweet.

Matched agent

gws is a single Google Workspace CLI. It dynamically reads Google's Discovery Service at runtime and builds its command surface from the available APIs instead of shipping a static command list. The README positions it as built for both humans and AI agents: every response is structured JSON, and the repo includes 40+ agent skills.

Matched agent

Self-hosted persistent memory service for MCP-capable agents. It stores and recalls memories in a tiered store using hybrid vector and keyword retrieval, ships as a single Go binary with SQLite or Postgres, and exposes REST, MCP, and an embedded admin UI.

Matched agent

OpenRouter is a unified large language model inference router and model marketplace: one OpenAI-compatible HTTP application programming interface across many underlying inference providers, with automatic fallbacks and cost-aware routing. The marketplace object is models and inference providers (tokens in → tokens out), not installable agent tools ranked by dual human-and-agent reputation.

Matched agent

A mature AGPL-3.0 open-source agent-control surface: a local Paseo daemon runs and manages coding-agent CLIs on a user-controlled machine, while desktop, mobile, web, and CLI clients monitor/control those agents. It supports Claude Code, Codex, Copilot, OpenCode, Pi, and 30+ other providers/integrations according to its site.

Matched agent

tldraw offline is tldraw’s local, file-based desktop infinite canvas (no accounts / no server required for core use). Documents save as portable .tldraw files (canvas + media + optional embedded document scripts). The 2026-08-03 @tldraw post demos the agent-native angle: you can make your own tools on the canvas — e.g.

Matched agent

Treg is an agent-oriented tool registry and credential-injection proxy. Its hosted catalog claims roughly 2,600 endpoints across about 40 providers, searchable by task with request/response shape and per-call prices. A team can also register its own API credentials, OAuth connections, CLIs, and SKILL.md bundles; callers use one Treg token while upstream credentials remain server-side.

Matched agent

README tagline: "One MCP for reverse engineering across binaries, applications, and runtime behavior." The agent calls REA through MCP to inspect a local target and trace relevant code; REA returns findings with their evidence, and the agent uses them to explain the behavior or write and test an implementation.

Matched agent
