Free AI Agent Builders
Which AI agent builders, automation platforms and agent sandboxes you can start with for free today, how much you get, what limits it and what the first paid plan costs, read from each tool's own page.
Free allowances read on each provider's own pages, all checked on or after . AI agent tools change their credits and plans often, sometimes month to month: confirm the terms on the tool's page before you build on them.
AI agent builders you can start with for free today include Runable (1,500 credits a day, no subscription), Activepieces (1,000 credits a month, unlimited flows), Daytona ($200 in free compute), MindStudio (one agent, 1,000 runs a month), and Make (1,000 credits a month). Each of the 15 free allowances below links to the tool's page that states it, with its main limit, whether a card is needed and what the first paid plan costs.
AI agent builders let a founder hand work to software: an assistant that answers email, an agent that researches leads, a flow that moves data between apps with an AI step in the middle. Developers who code their own agents need somewhere to run them, which is what agent sandboxes and cloud browsers are for. Most of these tools let you start free, with credits, a monthly allowance or a self-hosted edition.
The headline rarely tells you how far it goes. Free credits can last a week, a free plan can cap runs or tasks each month, a free edition can be self-hosted only, and sandbox credits are spent by the hour. Each tool below shows its free allowance, its main limit, whether a card is needed and what the first paid plan costs, quoted from the tool's own page with the date we read it.
Which tools we picked and the order they appear in are our editorial choices; the terms are the tools'. Several of these tools pay us a referral commission when someone signs up through our link: those links are labeled, and they play no part in which tools are listed or where.

How this comparison is built
The list covers AI agent builders, workflow automation platforms with AI agent steps, and agent sandboxes and cloud browsers that a founder can start with for free today without applying to a program. The order and the "best for" notes are our editorial reading of each tool's terms. Every term comes from the tool's own pricing or documentation page on the date shown, never from a third-party list; follow each link for the full conditions. Credits that reset each month, a cap on runs or tasks, or a free option that is self-hosted only can matter more than the headline, so the comparison quotes them wherever the tool states them. Several of these tools pay StartupPerks a referral commission, and their links are labeled as referral links; that decides neither whether nor where a tool appears, and no tool pays for a placement on this page.
