Airtop vs Fellou (2026): which should you pick?

Pick Airtop if

• Fits if you need to automate a website or vendor portal that has no API
• Works for developers adding a cloud browser to agents they already run in n8n, Zapier or Make

Look elsewhere if

• Tight if you're staying free: 1 deployed agent and 1,000 credits a month, with Mark on a 7-day trial
• Pricey if Mark is what you came for, as it's only included from the $189 Professional plan
• Watch out: Starter at $29 allows 3 sessions at once and 10 agents; a custom proxy and dedicated support start at $189
• Not for you if you might want your money back, as refunds need a request within 5 business days and no credits used
• Skip it if you want a phone or desktop app, since Airtop runs on the web only

Pick Fellou if

• Fits if you want a browser that runs a few web tasks for you each month
• Works for someone on a Mac or Windows PC who wants research reports

Look elsewhere if

• Tight if you run it often: Plus is about 8 tasks and Pro about 20 a month
• Watch out: the vendor says real use varies from its Sparks estimates
• Not for you if you use Linux, iPhone or Android, as only Mac and Windows builds are listed
• Watch out: Ultra's unlimited Sparks is marked limited time

Airtop

• Usage is metered in credits. The Free plan renews 1,000 a month and allows 1 deployed agent.
• Starter is limited to 3 simultaneous sessions and 10 deployed agents; a custom proxy and dedicated support start at Professional.
• Mark is included from the Professional plan. Free and Starter get a Mark trial of 7 days or until the credits are used.
• A refund of the last charge is offered only within 5 business days and only if no credits were used in that billing period.

Fellou

• Usage is metered in Sparks: the vendor estimates about 4 tasks on the free bonus and about 20 a month on Pro, and says real use varies.
• The free plan's 1,000 Sparks are a new-user bonus, not a monthly refill.
• The Ultra plan's unlimited Sparks and scheduled tasks are marked limited time on the pricing page.
• The download page lists Mac and Windows builds only, with no Linux, iOS or Android app.

Airtop

Agent Builder

Describe a workflow in plain English and Agent Builder builds and tests it, then compiles it into reusable code so the same input gives the same output on each run.

Schedules and triggers

Deployed agents run on a schedule or are started by a webhook or an event in a connected tool, and they are designed to repair a broken run on their own.

Cloud browsers

Agents sign in to websites and portals in browsers hosted in the cloud, with saved login profiles, built-in proxies, CAPTCHA solving and up to 100 parallel sessions.

Integrations and APIs

Prebuilt integrations cover HubSpot, Google Ads, Google Workspace, Slack and Airtable, and agents can call any REST or GraphQL endpoint using keys held in a vault.

Mark

An agent for marketing and sales work that researches your company, plans a go-to-market approach and builds the agents, with contact data and email verification built in.

Use from other platforms

A web agent can run as a step in n8n, Zapier or Make, or be driven from Claude Code and Codex. Developers also get a REST API and Node and Python SDKs.

Fellou

Plan first, then act

Fellou turns a goal into an action plan that you can review, approve and edit before it starts executing.

Browser automation

The Browser Use feature automates workflows that span sites, such as scraping data and filling in forms, from a single command.

Deep research reports

It searches across the web, including logged-in accounts such as Reddit, and produces reports with sources you can check.

Computer Use

With permission, the agent can operate local apps and manage files on the desktop, beyond the browser window.

Scheduled tasks

Tasks can run on a schedule; the free plan allows 2, Plus 3 and Pro 5, and Ultra is listed as unlimited for a limited time.

Eko open-source framework

The vendor also publishes Eko 2.0, an open-source framework for building your own agents, documented separately from the browser.
