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 →

E2B

87/100open sourcefreemiumexplicit relation

Each sandbox spins up in ~150ms with its own OS, giving agents a safe space to run untrusted code. Supports Python, JavaScript, and any language via custom Dockerfiles. Used by AI coding assistants, data analysis agents, and code interpreters. SDK available for Python and JavaScript with a simple API for programmatic sandbox control.

Free (Hobby) tier includes $100 free usage credit, 1-hour max sandbox runtime, and 20 concurrent sandboxes. Pro tier ($150/mo + compute) extends sandbox lifetime to 24 hours, 100+ concurrent sandboxes, and custom Docker templates. Pay-as-you-go compute is billed per-second at ~$0.0504/vCPU-hr and ~$0.0162/GB RAM-hr. Enterprise tier offers dedicated microVM clusters, VPC peering, SOC 2 Type II compliance, and 99.9% SLA with custom commitments.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 →

Skyvern

80/100open sourcefreemiumexplicit relation

Skyvern automates browser-based workflows using LLMs and computer vision instead of brittle XPath or CSS selectors. It understands web pages visually, navigating forms, clicking buttons, and extracting data like a human would. Achieved 85.85% success rate on WebVoyager benchmark and SOTA on WRITE tasks for RPA. 21,000+ GitHub stars, AGPL-3.0 licensed. Skyvern Cloud offers managed usage-based hosting for teams that prefer not to self-host the infrastructure.

Open-source AI browser automation agent (AGPL-3.0, 23k+ GitHub stars) that uses computer vision and LLMs to interact visually with websites without brittle DOM selectors. The self-hosted version is $0 (bring your own LLM keys and infrastructure). Skyvern Cloud offers a Free trial ($0 with 5,000 starter credits / $10 credit), Hobby tier (~$29/mo), Pro / Growth plans ($99–$199/mo with managed residential proxies, automated CAPTCHA solving, and anti-bot bypass), and Enterprise custom pricing with dedicated infrastructure, SOC2/SSO, and SLA support.Review →

Microsandbox

76/100open sourceexplicit relation

Microsandbox provides hardware-level isolated sandboxes for AI agents to execute code safely on local machines. Using libkrun microVMs and a 320ms bare-metal Linux/KVM homepage benchmark, it offers stronger isolation than Docker containers while staying lightweight enough for dev workstations. OCI-compatible with Python and Node.js runtimes. Apache-2.0 licensed with 6.6K+ GitHub stars.

Free and 100% open source under the Apache-2.0 license. Microsandbox has zero software licensing fees, subscription tiers, or seat restrictions; it runs locally or self-hosted on your own hardware infrastructure (Linux KVM, macOS Apple Silicon, or Windows WHP) with $0 vendor compute markup.Review →

Tabstack

freemiumexplicit relation

Tabstack is Mozilla's browser infrastructure service for AI agents, providing clean markdown extraction, structured JSON data, and automated browser actions through a fast API. With two-tier fetch escalation that achieves sub-600ms latency for static pages, robots.txt compliance, and ephemeral data handling, it offers an ethical alternative to aggressive web scraping tools — complete with an MCP server for Claude and Cursor integration.

Freemium / Credit-based API. Includes 10,000 free trial credits upon signup (no credit card required). Team plan is $99/mo for 500,000 credits, with Pay-As-You-Go available. Per-action costs are 10 credits (Markdown extraction), 50 credits (JSON extraction), 100 credits (automation), and 250-350 credits (autonomous research).

Hyperbrowser

80/100freemiumexplicit relation

Hyperbrowser is a cloud browser platform for AI agents and automation, providing managed Chrome sessions through Playwright, Puppeteer, CDP, REST, Python, and Node.js SDKs. Docs cover Stagehand, stealth/proxy options, ad blocking, recordings, scraping APIs, and credit pricing without promising universal CAPTCHA or anti-bot bypass.

Freemium cloud browser infrastructure (BaaS) for AI agents and web scraping. Free tier includes 5,000 credits ($5 value) and 1 concurrent browser. Paid plans start at Startup ($30/mo, 30,000 credits, 25 concurrency) and Scale ($100/mo, 100,000 credits, 100 concurrency), with Enterprise tiers for 1,000+ concurrency. Usage is credit-based ($0.001/credit): active browser sessions cost 100 credits/hr ($0.10/hr), residential proxy traffic costs 10,000 credits/GB ($10/GB), and scraping costs 1–10 credits/page.Review →
