Search, fetch, and browser automation for agents. Free Search and Fetch; metered browser runs. Leyline uses it as intake evidence crawl, not as a locked vendor.

Browser automation for tests and agents. Use the browser slice without taking the whole test-runner product box.

Data framework for retrieval and agents. Memory and index slices, not a whole 'RAG product' box.

Workflow automation. Compose and schedule slices that agents can call without owning the whole iPaaS.

Neural web search API aimed at agents. Search slice with citations, distinct from crawl-the-page tools.

Hosted browsers for agents. Browser slice without running Playwright locally.

Context.dev (also @getcontextdev; YC S26 per founder/company bios) markets itself as a unified web-context API for software and agents: scrape, crawl, search, brand/people enrichment, monitors, MCP, and SDKs — one API key.

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

Open-source application platform to build, deploy, operate, and scale apps on infrastructure you own (VPS, dedicated, cloud VM, homelab). Pitch: replace a pile of deployment tools + managed services with one OSS control plane. Interfaces claimed: web dashboard, native desktop app, CLI, REST API, MCP for AI agents.

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.

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.

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.

Open-source memory system for agents and teams. It connects company sources such as Slack, GitHub, and Linear so agents can recall shared context through one memory API, an SDK, or an MCP server, with an optional Cognee Cloud for managed scale.

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.

Hark turns HTTPS webhooks into clean, source-branded iPhone notifications. Each service gets its own name, avatar, destination URL, and secret endpoint. Intended senders: CI, agents, scripts, monitors — anything that can POST JSON. Hosted product: https://hark.ryan.ceo Public monorepo: https://github.com/R44VC0RP/hark (TypeScript; Node 22+; compose.yaml / Dockerfile present in tree)

Is Agentic is a free, public Vercel product that scores how ready a public HTTP or HTTPS website is for AI agents. Submit a URL on the home page. Ora runs and scores every technical check. Is Agentic groups those checks by maturity and applicability, then publishes a score, evidence, recommended fixes, and a shareable report.

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.

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.

Refero is a design-research platform of real web and iOS product interfaces, user flows, UI patterns, and visual styles. Its Refero MCP exposes structured research to agents so they can study relevant screens and flows before implementation.

Soar is a consumer flight product (find/book cheap flights) shipping a Flight Booking MCP so agents can search, book, pay, and manage trips (plus public stay search). Positioning vs many flight MCPs: book + pay, not search-only. Launch (@SoarAI, 2026-07-26): > Today we’re releasing the first MCP to find and book flights, always at market rates.

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.

Railcode is Yakko Majuri’s secure / governed cloud for internal software — apps and agents (“internal Vercel” framing on the launch post). Build with your own tools; deploy into a company-governed sandbox with auth, permissions, data, and connectors centralized.

Open-source shared persistent memory for AI agents, backed by Notion. A Lore vault is a Notion page with Projects, Topics, Memories, Entities, and Facts databases so later sessions and people can reuse experiential knowledge, follow-up tasks, decision records, and procedures. Age

The computer underneath the agent. Instant full cloud desktops (GUI, browser, filesystem, terminal, apps) that AI agents can see and control via API — boot claimed under ~500ms. Always-on until stopped. Linux + Windows GA; Mac closed beta. People use it three common ways (docs): 1.

Agency is a local card-feed app from Browser Use: a coding-agent coordinator prepares suggestion cards; the human approves with one click (Send / Apply / Merge). Thesis (X + README): agents find useful work; you decide — “Never prompt again.

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.

Site title Transitions.dev: UI transitions for AI agents. README: “an interactive collection of reusable CSS transitions. Each card on the index page demonstrates a different interaction pattern and ships a copy-ready, portable CSS snippet.” Live index groups cards as All / Essential / AI Agents / Effects / Texts / Pro.
