Browser Use

85/100open sourcefreemiumexplicit relation

Browser Use is an open-source AI agent framework with 99K+ GitHub stars enabling LLMs to control web browsers via natural language. Y Combinator-backed, it lets agents navigate sites, fill forms, extract data, and complete multi-step tasks autonomously. Built on Playwright with vision-based element detection, multi-tab management, cookie persistence, and self-correcting actions. Supports OpenAI, Anthropic, and local models with a simple Python API for building custom browser agents.

Browser Use is open-source under the MIT license for self-hosting with BYOK LLM keys. The managed Browser Use Cloud service provides a free tier (3 concurrent sessions, 10 tasks), a Dev plan at $29/month ($29 credits, 25 sessions, stealth browsing), a Business plan at $299/month (200 sessions), and custom Enterprise tiers.Review →

Stagehand

85/100open sourceexplicit relation

Stagehand is an open-source browser-agent SDK from Browserbase that combines deterministic browser automation with AI primitives such as act(), extract(), observe(), and agent(). Instead of relying only on brittle selectors, developers can use natural-language actions, Zod-backed structured extraction, page observation, action caching, and Browserbase cloud-browser infrastructure for production web automation.

100% free and open-source (MIT License, $0 software cost). Users bring their own LLM API keys (OpenAI, Anthropic, etc.) for token usage. Runs locally on Playwright/Chromium for free, with optional integration to Browserbase managed cloud browser infrastructure (Free tier with 1 hr/mo, Developer at $20/mo, Startup at $99/mo, and Custom enterprise plans).Review →

MCP InspectorMCP Inspector is the official interactive developer tool from the Model Context Protocol team for testing, debugging, and validating MCP servers. It provides a visual interface to inspect available tools, test transport configurations, export configs for different clients, and verify protocol compliance during MCP server development.DeepEvalDeepEval is an Apache-2.0 Python framework for evaluating LLM apps, RAG systems, agents, MCP workflows, and safety behavior with repeatable test cases. It works locally and in CI/CD, then connects to Confident AI for hosted reports, observability, red teaming, and governance when teams need shared evidence instead of ad-hoc prompt reviews and manual QA.reviewdogreviewdog is an open-source automated code review tool that integrates any linter or static analysis tool with GitHub, GitLab, Bitbucket, and Gitea pull requests. Parses output in errorformat, Checkstyle XML, SARIF, and JSON formats to post inline review comments on changed lines only. Works with GitHub Actions, Travis CI, CircleCI, GitLab CI, and Jenkins. Supports 40+ languages through universal linter adapter architecture.LangfuseLangfuse is an open-source LLM engineering platform with 29K+ GitHub stars for tracing, evaluating, and monitoring AI applications. Acquired by ClickHouse, it provides detailed traces of LLM calls, prompt management with versioning, dataset-based evaluation, user feedback collection, and cost tracking. Framework-agnostic with native integrations for LangChain, LlamaIndex, OpenAI SDK, and Vercel AI SDK. Offers both self-hosted deployment and a managed cloud service.StablyStably enables developers to create QA tests in plain English using a no-code editor, with AI ensuring tests remain valid as the application evolves through self-healing locators and assertions. It lowers the barrier to high-quality QA for startups by eliminating the need for scripting knowledge, automatically adapting test steps when UI elements change position or structure.CUA (Computer-Use Agent)Open-source computer-use infrastructure for agents that need to drive desktop environments in the background. CUA includes Cua Driver, Sandbox, Run, Bench, and Verified Data across Linux, Windows, macOS, and Android, with MCP and CLI surfaces for screenshots, accessibility trees, keyboard/mouse actions, shell commands, task evaluation, and fleet execution.ChromaticChromatic is a Storybook-first visual testing and UI review platform for design systems and frontend teams. It publishes Storybook, captures component snapshots, reviews pull-request diffs, and supports interaction tests, accessibility checks, TurboSnap, SteadySnap, Playwright/Cypress workflows, and Storybook MCP context.MomenticMomentic is an AI-native testing platform that lets teams write end-to-end tests in plain English. It features auto-healing test selectors that adapt to UI changes, instant mobile device emulators, built-in visual regression testing, and AI-powered flaky test handling.
