Most AI tools can tell you what to do on a website; they can't actually do it. A newer category of software closes that gap: it gives an AI agent a real browser — either on your machine or hosted in the cloud — so it can log in, click, fill out a form, scrape data, or complete a multi-step task the same way a person would, CAPTCHAs and all. Some of these tools are aimed at individual developers automating their own workflows; others are built to run thousands of agent sessions at once for a company. Here are seven real ones, and what actually separates them.
The short version: if you want a consumer-friendly AI browser that plans a task and lets you approve it before it runs, Fellou and Genspark are the two built for that. If you're a developer who wants to self-host something free and open source, ego-lite and Page Agent cost nothing to try. If you need to scale to thousands of concurrent sessions or get past CAPTCHAs and bot detection reliably, Notte, BrowserAct and Airtop are built for production volume.
1. Fellou — shows you its plan before it acts autonomously
Fellou is an AI browser built so an agent can carry out real, multi-step tasks — research, form-filling, scheduling — across websites, while showing you its planned steps up front so you can intervene before anything happens. It handles multi-source research with traceable reports, manages local desktop files, learns from your browsing history over time, and is built on an open-source "Eko" framework (MIT-licensed, roughly 4,900 GitHub stars) that developers can extend.
Pricing: free tier (~4 tasks/month); Plus $19/month (~8 tasks); Pro $39.90/month (~20 tasks, most popular); Ultra $199.90/month (unlimited).
Watch out for: its "3.1x faster than OpenAI" performance claims are unverified vendor marketing, and letting it handle logins and CAPTCHAs autonomously carries real risk if you're not watching closely.
Pick Fellou if: you want to review and edit an agent's plan before it executes, and you value that the underlying framework is genuinely open source.
2. Genspark — runs models locally so it keeps working offline
Genspark takes a different approach: instead of sending every request to one company's cloud, it runs a library of 169+ AI models directly on your device, so it keeps functioning without a network connection and isn't locked into one provider. Its "Super Agent" handles higher-stakes autonomous tasks like phone calls and bookings, an "Autopilot Mode" handles hands-off browsing and price comparison, and it ships an MCP Store with 700+ tool integrations.
Pricing: free tier for on-device features (Windows/Mac); paid Plus tier for expanded access; Enterprise tier for businesses.
Watch out for: its reported growth figures (6,000+ business clients within six months) are extraordinarily fast and worth verifying independently, and a September 2025 security concern was flagged but never comprehensively documented publicly — worth asking about directly before deploying it on anything sensitive.
Pick Genspark if: you want offline-capable, model-agnostic automation and are comfortable with an agent that can take higher-stakes actions like placing calls.
3. BrowserAct — a stealth browser built to get past CAPTCHAs and bot detection
BrowserAct is purpose-built for the wall most scrapers hit: sites that block anything that looks like a bot. It runs a stealth browser engine with fingerprint, network and session isolation, solves CAPTCHAs, and includes adaptive agents that can rebuild a scraper automatically when a site's layout changes, plus a human-in-the-loop handoff for cases the AI can't resolve alone. It integrates with Claude, Cursor, Codex and no-code tools like Zapier, Make and n8n.
Pricing: pay-as-you-go credit system, no fixed tiers; 7-day free trial; real monthly cost depends on which components (stealth browser, proxy bandwidth, workflow steps) a task uses.
Watch out for: the credit-based billing is genuinely hard to estimate in advance, and its claimed 99%+ CAPTCHA success rate isn't independently verified.
Pick BrowserAct if: your main obstacle is getting blocked by anti-bot measures on the sites you need to automate.
4. Notte — cloud-hosted browser sessions that scale to thousands at once
Notte handles the hosting and plumbing of running browsers for AI agents at scale: cloud-hosted sessions with anti-detection and CAPTCHA solving built in, natural-language agent instructions instead of scripted actions, structured data extraction from JavaScript-heavy sites, and serverless browser functions that scale to 5,000+ concurrent sessions. It's open source (about 2,000 GitHub stars, SSPL-1.0) and offers an on-premise, HIPAA-compliant option for enterprise.
Pricing: free tier ($10 one-time credits, 5 concurrent browsers); Developer $20/month; Startup $100/month (most popular); Enterprise on quote; usage runs $0.05/hour per session plus $10/GB for residential proxies.
Watch out for: usage-based pricing can climb quickly at real production volume, it competes directly with well-funded rivals like Browserbase and Firecrawl, and you still need to supply your own LLM API keys separately.
Pick Notte if: you're a developer building a product that needs many agents browsing in parallel, and you want that infrastructure open source rather than a black box.
5. ego-lite — free, and it reuses your existing browser logins
ego-lite solves a specific annoyance: getting an agent logged into every site it needs separately from your own sessions. It's a free, open-source (MIT, ~2,700 GitHub stars) browser that lets an agent inherit your existing Chrome login data and history, runs multiple isolated browsing tasks in parallel "Spaces," and integrates directly with Claude Code, Codex and Cursor.
Pricing: entirely free and open source.
Watch out for: it's local-only with no cloud infrastructure to scale to (unlike Notte), the project and community are still young, and handing an agent your real login credentials is a security tradeoff worth thinking through before you do it.
Pick ego-lite if: you're one person automating your own accounts locally, not running agent browsing at company scale.
6. Page Agent — reads the page's actual code instead of guessing from a screenshot
Page Agent, built by Alibaba and free/open source (MIT, ~27,700 GitHub stars), takes a more precise approach than most competitors: it reads the real structure of a webpage (the DOM) and lets an AI issue natural-language commands directly against real page elements, instead of taking a screenshot and guessing where to click. That makes it faster and less brittle when a layout shifts slightly. It needs no full headless browser setup and no Python, and works with locally deployed LLMs.
Pricing: entirely free and open source.
Watch out for: it depends on a reasonably clean DOM structure, so it's less reliable on obfuscated or heavily dynamic interfaces, and its MCP Server support is still in beta.
Pick Page Agent if: you want a lightweight, fast, free tool for reliable in-page automation without running a full browser stack.
7. Airtop — automates the old internal tools that don't have an API at all
Airtop exists for the gap Zapier and Make can't fill: business tools without a proper API — old internal portals, niche vendor dashboards. It runs authenticated cloud browser sessions with built-in proxies and CAPTCHA solving, a password vault for credentials, and an Agent Builder that compiles one-off automations into reusable code. It ships MIT-licensed open-source SDKs for Node.js and Python, native integrations with Claude, Codex, n8n, Make and Zapier, and is SOC 2 Type II and HIPAA compliant.
Pricing: free tier (1,000 credits, 3 sessions, no card); Starter $26/month; Professional $170/month; Enterprise $502/month (10% off annual).
Watch out for: the credit model can get expensive at real volume, its open-source SDKs still have limited GitHub adoption, and it needs more setup than a pure no-code tool like Zapier.
Pick Airtop if: you need to automate authenticated, API-less business tools and want SOC 2/HIPAA compliance out of the box.
Quick comparison
| Tool | Best for | Pricing model |
|---|---|---|
| Fellou | Reviewable plans before autonomous execution | Free (~4 tasks); from $19/mo |
| Genspark | Offline, model-agnostic automation | Free tier; paid Plus/Enterprise |
| BrowserAct | Getting past CAPTCHAs and bot detection | Pay-as-you-go credits |
| Notte | Scaling to thousands of sessions | Free tier; from $20/mo + usage |
| ego-lite | Free, local, reuses your logins | Free, open source |
| Page Agent | Fast, DOM-based automation, no screenshots | Free, open source |
| Airtop | Automating tools with no API | Free tier; from $26/mo |
The right pick here really depends on who's running the agent and at what scale. If you're one developer automating your own workflow, ego-lite and Page Agent cost nothing and run locally. If you're building a product that needs to browse the web reliably at volume, Notte, BrowserAct and Airtop are the ones built for cloud-scale sessions and anti-bot resistance. And if you just want a consumer AI browser that plans before it acts, Fellou and Genspark are the most polished on-ramps — just supervise the higher-stakes actions closely, since an agent that can fill in forms and click through logins is also an agent that can do real damage if it misreads the page.
