Browserbase
Headless browser cloud infrastructure for autonomous AI agents
About Browserbase
Browserbase is a developer platform that provides headless browser infrastructure and cloud execution environments built specifically for autonomous AI web agents. It solves the hardest challenges of automated browser interactions—including fingerprinting management, bot-detection evasion, CAPTCHA solving, session persistence, and full visual debugging. As AI agents transition from text chat to acting directly on the web, running local browser instances quickly breaks down due to scaling limits and anti-bot blocks. Browserbase provides a scalable serverless fleet of stealth Chromium browsers that agents can pilot via Playwright, Puppeteer, or Stagehand. Trusted by AI startups and enterprise automation teams, Browserbase enables developers to build reliable web scraping pipelines, automated booking assistants, competitor monitors, and end-to-end workflow bots.
Browserbase includes Session Replay, which automatically records video, DOM state, network waterfalls, and console logs for every automated browser run. This allows developers to visually inspect exactly where and why an AI agent took a wrong turn or got stuck. The platform also provides Stagehand—an open-source AI web automation framework created by Browserbase that allows agents to find elements and perform complex actions using natural language instructions (e.g. `page.act('click on the cheapest flight')`) with self-healing selectors.

Frequently Asked Questions
What is Browserbase used for?
Browserbase is used by AI developers to run headless browsers in the cloud, allowing autonomous AI agents to browse the web, click buttons, fill forms, and extract data reliably.
How does Session Replay work in Browserbase?
Every browser session records a complete video replay alongside network requests, console logs, and DOM snapshots so you can debug what your AI agent saw and did.
What is Stagehand?
Stagehand is an open-source web browsing SDK built by Browserbase that allows LLMs to control browsers using simple natural language actions like 'click', 'extract', and 'observe'.
Free Plan
Free tier provides 1 hour of browser runtime per month and full access to Session Replay.
Paid Plan
Developer plan at $20/month with 20 browser hours and automated CAPTCHA solving. Scale plan at $100+/month with dedicated residential proxies and high-concurrency pools.

Agno
High-performance multimodal AI agent framework with native memory and speed
Agno (formerly Phidata) is a lightweight, ultra-fast Python framework engineered for building production-grade autonomous multi-agent systems with native memory, knowledge retrieval, and multimodal reasoning capabilities. It is designed to replace bloated agent frameworks with a pure, pythonic developer experience. Agno agents operate up to 10x faster than legacy orchestration libraries by eliminating unnecessary abstractions. With built-in support for vector databases (PgVector, Qdrant, Pinecone), structured output schemas, and agent-to-agent delegating protocols, developers can build complex autonomous assistants with under 20 lines of clean code.
Langfuse
Open source LLM observability, tracing, and evaluation platform
Langfuse is an open-source LLM engineering and observability platform built for teams developing production-grade generative AI applications and autonomous multi-agent pipelines. It captures granular traces across token usage, prompt versions, latency bottlenecks, and retrieval accuracy, giving developers complete visibility into model behavior at runtime. By integrating seamlessly with major AI frameworks such as LangChain, LlamaIndex, LiteLLM, and the OpenAI SDK, Langfuse eliminates the guesswork from debugging complex agent execution trees. Developers can monitor production cost metrics, identify hallucinated responses, and run rigorous continuous evaluation suites on live traffic.
Relevance AI
Build and deploy custom AI agents and workflows
Relevance AI is a platform designed to create AI workforces by combining LLM agents, tasks, and data pipelines. It provides an intuitive low-code workspace to build autonomous agents that execute multi-step operations.
