If you're building an AI agent that needs to actually use the web — log into a site, click through a checkout flow, scrape a page that requires a session — you eventually hit the same problem: a plain API call isn't enough, and running your own fleet of headless browsers is a real infrastructure job (proxies, CAPTCHAs, memory leaks, the works). Airtop and Browserbase both exist to take that job off your plate by giving your agent a real, managed browser to drive. But they're not solving quite the same problem, and picking the wrong one means either overpaying for infrastructure you don't need or hitting a wall the tool wasn't built for.
What each one actually is
Browserbase gives you real, remote browser instances — not a simulation — built specifically for AI/ML developers and enterprises that need reliable, scalable browser automation for agents. It's infrastructure: you point Playwright or Puppeteer at it and it handles the operational burden of running and securing headless browsers at scale, including HIPAA/DPA-compliant options for regulated industries like healthcare, fintech, and legal.
Airtop is aimed one level higher: automating authenticated, legacy, or API-less web apps — the kind of internal tool or old enterprise system that Zapier and Make simply can't touch because there's no API to connect to. It ships an open-source SDK (MIT license) for Node.js and Python, and leans on native integrations with Claude, Codex, n8n, Make, and Zapier so it slots into workflows that already exist rather than replacing them.
Pricing
Browserbase starts with a free tier: 3 concurrent browsers and 1 hour/month, plus $5 of model tokens — enough for light evaluation only. Developer is $20/month for 25 browsers and 100 hours; Startup is $99/month for 100 browsers and 500 hours; Scale is custom pricing with 250+ browsers and HIPAA/DPA support. Watch out for metered add-ons (Search, Fetch, model tokens) — they can roughly double the headline plan cost at moderate volume.
Airtop is also freemium: the free tier gives 1,000 credits and 3 sessions with no card required. Starter is $26/month, Professional is $170/month, Enterprise is $502/month (10% off billed annually). It's SOC 2 Type II and HIPAA compliant across the board, which matters if authenticated-app automation touches sensitive data.
Where each one wins
Pick Browserbase if you're building AI agents that need raw, reliable browser infrastructure at scale — scraping, testing, or automation workflows where you're already comfortable driving Playwright or Puppeteer yourself and just want someone else to run the fleet. It's the more "infrastructure-grade" option, with compliance support built for regulated industries running high volumes.
Pick Airtop if your actual problem is automating a specific authenticated or API-less app — the internal CRM with no API, the vendor portal you have to click through by hand every week — and you want that automation to plug directly into an agent stack (Claude, Codex) or a no-code workflow tool (n8n, Make, Zapier) without writing much glue code yourself.
Where each one is weaker
Browserbase's own core dependency — Playwright/Puppeteer — is open source and free to run yourself; you're explicitly paying for the ops burden to go away, not for automation logic. If your volume is low, self-hosting might be cheaper. Airtop's open-source SDKs are still early (16 and 6 GitHub stars at last check), so you're trusting a young project with less community mileage, and its credit model can climb to $502/month at the top tier.
| Airtop | Browserbase | |
|---|---|---|
| Core focus | Automating authenticated / API-less web apps | General-purpose managed browser infrastructure |
| Free tier | 1,000 credits, 3 sessions | 3 concurrent browsers, 1 hr/mo, $5 tokens |
| Entry paid tier | $26/mo (Starter) | $20/mo (Developer, 25 browsers/100 hrs) |
| Top tier | $502/mo (Enterprise) | Custom (Scale, 250+ browsers) |
| Compliance | SOC 2 Type II, HIPAA | HIPAA/DPA on Scale tier |
| Integrates with | Claude, Codex, n8n, Make, Zapier | Playwright, Puppeteer (you drive it) |
The short version: Browserbase is browser infrastructure you drive yourself with code you already know; Airtop is a higher-level automation layer aimed at the specific pain of apps that have no API and require a login. Some teams will genuinely want both — Browserbase for the scraping and testing workloads, Airtop for the one internal tool that's been eating an hour of someone's week for years.
