Browserbase alternatives (2026)

Browserbase: The browser infrastructure that lets you focus on the agent, not the fleet.

Its Catch: Another service to pay for and depend on.

Below: 8 free or free-tier tools from the same category (browser automation tools), free and open source first, then the closest match by shared tags. Each keeps its own Catch.

1.StagehandAI-native browser automation that mixes code and natural language
Free / OSS · OSS/MIT · 25.7k GitHub stars
VerdictThe right abstraction for browser automation that needs to survive UI changes.
CatchAI calls add latency and cost. The natural-language parts are only as reliable as the underlying model. Debugging AI-driven steps is harder than debugging selectors.
2.Browser UseOpen-source framework for LLM-driven browser agents
Free / OSS · OSS/MIT · 118k GitHub stars
VerdictThe open-source foundation for browser-based AI agents.
CatchYou need browser infrastructure—Browser Use is a framework, not a managed service. Token consumption scales with page complexity. Anti-bot measures will block you without stealth tooling.
3.Playwright MCPOfficial Microsoft MCP server for Playwright browser automation
Free / OSS · Apache-2.0 · 38.4k GitHub stars
VerdictThe standard way to give MCP clients browser access.
CatchIt is a control interface, not a complete solution. You still need browser infrastructure (local Chromium or Browserbase). No built-in session management, authentication, or scaling.
4.Chrome DevTools MCPOfficial Chrome DevTools as an MCP server for coding agents
Free / OSS · Apache-2.0 · 53.8k GitHub stars
VerdictThe MCP browser for agents that need real DevTools, not just clicks.
Catchchrome-devtools-mcp@1.8.0 engines: "^20.19.0 || ^22.12.0 || >=23". 20.16 and 20.17 fail; 20.19 LTS is in engines. “Node ≥ 22.12” and “Node 20 fails” are both too blunt — README “LTS” is marketing; engines is the catch. A CLI is provided for use without MCP; official CLI docs call it experimental. Complementary to Playwright MCP —DevTools-grade traces, Lighthouse, heap snapshots, and --autoConnect, not a generic scraper or a Playwright replacement. Officially supports Google Chrome and Chrome for Testing only. Exposes browser content to the MCP client—do not point it at sensitive sessions. Usage statistics on by default (opt out with --no-usage-statistics). Needs a current Chrome.
5.agent-browserVercel Labs Rust CLI with compact a11y refs for agents
Free / OSS · Apache-2.0 · 44.2k GitHub stars
VerdictThe CLI browser for agents that want refs, not a full DOM dump. Restore or lose the session.
CatchDefault idle timeout is about one hour: the headless daemon shuts down and discards transient tabs/state unless you passed `--restore` (or another restore key). Headed, Safari/iOS WebDriver, and user-attached browsers are exempt; cloud-provider browsers are not. Tune with `--idle-timeout` or `AGENT_BROWSER_IDLE_TIMEOUT_MS`; `0` disables. This is CDP Chrome, not stealth—anti-bot pages will still block you.
6.SteelApache-2.0 browser API for AI agents — self-host or cloud
Free / OSS · Apache-2.0 · 7.8k GitHub stars
VerdictApache-2.0 agent browser API. Self-host Steel; pay Browserbase-shaped cloud only if you must.
CatchVs Browserbase (managed fleet), Stagehand (AI Playwright layer), Browser Use (LLM browser framework): Steel is the browser sandbox/API — bring your own agent logic. Self-host means Chrome resource cost; cloud is freemium/paid convenience. Anti-bot arms race still applies.
7.ScraplingBSD-3 adaptive scrape/crawl framework + MCP
Free / OSS · BSD-3-Clause · 88.5k GitHub stars
VerdictBSD-3 adaptive scrape/crawl + MCP. Self-run framework vs Firecrawl-shaped APIs.
CatchVs Firecrawl-style hosted scrape APIs: Scrapling is a library/framework you run (plus MCP), not a metered scrape SaaS with a managed anti-bot fleet. You own proxies, blockers, and ops; MCP does not erase site ToS or legal risk. Not a general browser-agent product like Browser Use/Steel.
8.Agent ReachMIT eyes for agents — public-web CLI, zero API fees
Free / OSS · OSS/MIT · 99.2k GitHub stars
VerdictMIT agent web CLI. Zero API-fee eyes; not Tavily/Exa-grade paid search.
CatchVs Tavily / Exa (paid search APIs): Agent Reach is CLI eyes on public surfaces without a search SaaS bill — not a ranked enterprise search product with SLAs. Site ToS, auth/cookie setup, and breakage are yours; some platforms need user-controlled sessions. Not a replacement for licensed data APIs.
