A free tier looks like a gift until you read the fine print. Most AI agent free plans are not really about giving you free work; they are a shaped sample, generous enough to hook you, capped tightly enough that real use pushes you onto a paid plan fast. That is fair, since running agents costs compute. The trouble is that the catches are scattered across run limits, gated features, connector counts, and trial clocks, so two free tiers that look alike can behave very differently once you depend on them.

This guide compares the free tiers honestly. It names what each platform actually gives away as of July 2026, groups platforms into four categories, names the catches to watch for, and gives you a checklist to evaluate any free plan. For a wider view of the market, pair it with our rundown of the cheapest AI agent platforms and our guide to AI agent pricing models.

What does each AI agent free tier actually give you?

Every limit below was checked against the vendor's own pricing page on 30 July 2026. The column that matters most is the unit, because a platform that sounds generous in credits can be stingy in runs, and vendors rarely publish a conversion.

Platform Free tier allowance Metered unit First paid step
MindStudio1,000 runs/month, 1 agent, 200+ models with no API keysRuns$20/month ($16 annual), unlimited agents and runs
Gumloop5,000 credits/month, 1 seat, 1 active trigger, 2 concurrent runs, unlimited flowsCredits$37/month, 20k+ credits, unlimited seats

LindyNo free plan, 7-day trial onlyNot applicablePlus $49.99/month
GravityFree tier, 1 agentAgents, then usage$20/month with $20 of usage included

Three things stand out. First, Lindy no longer has a free plan, having restructured to paid-only tiers with a 7-day trial, so any roundup still listing a Lindy free tier is out of date. Second, Relay.app is winding down entirely: it told customers on 16 July 2026 that it is shutting the service, new signups and free-to-paid upgrades are already disabled, free accounts close on 15 August 2026 and paid accounts on 14 September 2026, with unexported data deleted at each deadline. Many free-agent roundups published this year still list its free plan as available. Third, the two platforms ranking highest for free agent searches, Gumloop and MindStudio, meter in different units, which is why they cannot be ranked against each other without knowing your workload. A run in MindStudio may consume many credits' worth of work in Gumloop, and neither vendor publishes the exchange rate.

That pattern is the real lesson of this page. Two of the seven platforms here changed their free-tier status within the last month, in one case removing it and in the other removing the whole product. A free tier is a marketing decision, not a commitment, so treat any list of free plans, including this one, as a snapshot with a date on it rather than a standing fact.

What "free" really means in agent pricing

Free in agent pricing almost never means free work; it means free access up to a limit someone else chose. Every agent run spends compute and, for most tools, model API calls, so a vendor giving away unlimited runs would be paying your bill. The cheapest free tier on paper is often the most expensive once your real volume crosses the cap and the first paid step kicks in: Gumloop's free 5,000 credits become $37 a month the moment you need a second active trigger, a steeper first step than most of the field.

So the useful way to read a free tier is not "how much do I get for nothing" but "what does the vendor want me to feel before they charge me". A free chat assistant wants you fluent in its product. A no-code free plan wants your first workflow live so switching feels costly. Neither is dishonest. You just need to read the plan as a sample, then price the version you would actually run. Our explainer on AI agent pricing breaks the moving parts down.

Free as marketing, free as architecture

There are two honest kinds of free. Marketing-free is a hosted tier the vendor subsidises to win you; it ends at a cap. Architecture-free is open-source software you can run yourself with no licence fee, where your cost moves to hosting and time instead of a bill. One frees your wallet today and bills you later. The other frees the licence but hands you the operations. Knowing which kind you are looking at tells you where the real cost lives.

What are the categories of AI agent free tier?

AI agent platforms split into four rough categories, and each handles "free" in its own way. The split matters because the most common buyer mistake is comparing a chat assistant's free tier against a no-code automation free plan as if they were the same product. They solve different jobs and charge on different axes, so a fair comparison starts by sorting them first.

LLM assistants with a free chat tier

The big chat assistants give you a free conversational tier and, increasingly, light agent features on top. Free here usually means a daily or rolling message allowance, the older or smaller model, and limited access to tools like browsing or file actions. It is excellent for learning and one-off tasks. It is a poor fit for repeated, unattended work, because the free tier rarely runs on a schedule or touches your systems without you in the chat.

No-code automation platforms with free plans

Workflow and automation tools that have added agent steps typically offer a free plan with a monthly task or run allowance. Free gets you a taste: a few live automations, a subset of connectors, and basic logs. It suits a single tidy workflow. The squeeze comes when you add a second or third automation, since task counts and connector limits are exactly where these plans nudge you toward paying. Our Gravity versus Zapier comparison walks through that style of pricing.

Open-source and self-hosted options

Open-source agent frameworks are free to download and run. There is no licence fee and no run cap from a vendor. The cost moves to you: a server to host it, model API keys you top up yourself, and the hours to set up, secure, and maintain the thing. For a developer who wants control, that trade is often worth it. For someone who just wants work done, the operations burden is the real price tag.

Run-it-for-you platforms

The last category runs the agent for you, so you describe the outcome and the platform handles the work end to end. Some offer a small free trial; others, like Gravity, pair a genuine free tier that covers one agent with paid plans from $20/month that include $20 of usage. This is the model to weigh carefully, because the first paid step is a published number rather than a surprise. We compare the leaders for early-stage teams in the best AI agent platforms for startups.

What are the catches in a free AI agent plan?

The catches in free agent plans are predictable once you know where to look, and they cluster in six places. The catch that surprises new buyers most is not the run cap they expected; it is the jump in price at the first paid step, which can multiply the monthly cost the moment a single cap is crossed. Read these six before you build anything you would hate to lose.

Run, task, and message caps

The headline limit is almost always a count: messages per day, tasks per month, or runs per period. It is easy to read and easy to blow past. A workflow that fires once a day feels free until a busy week triples your runs. Always estimate your real volume on a heavy week, not an average one, and check what happens the moment you cross the line.

Feature gating and connector limits

Free plans often run the agent but hold back the parts that make it useful at work: scheduling, team seats, audit logs, priority support, and the better model. Connectors are a favourite gate, since the integration you actually need is frequently reserved for a paid tier. A free plan that cannot connect to your real tools is a demo, not a tool. List your must-have integrations first, then check the free tier against that list.

Time-boxed trials and branding

Some "free" offers are really trials with a clock; full features for a fortnight, then a wall. Others stamp provider branding on every output or add the vendor's name to outbound emails, which is fine for testing and awkward in front of a client. Neither is a dealbreaker on its own. Both change the maths, so confirm whether your free tier is genuinely ongoing or a countdown wearing a free label.

How do you evaluate an AI agent free tier?

You evaluate a free tier by pricing the version you would actually run, not the version they advertise. Walking a written checklist before committing forces the post-cap question to the front, which is where the surprise upgrades come from. Work through the points below against any plan, with the vendor's current pricing page open beside you.

The questions to ask every plan

Run this list against two or three candidates and the real winner usually separates from the cheapest-looking one. For a formal version you can hand to a vendor, our AI agent platform RFP template turns these questions into a structured request, and our guide to agent cost models explains how each pricing axis adds up.

Why pay-per-use is an honest alternative to a free tier

Usage-based billing answers a different question than a free tier; it asks how much a run is worth rather than how many you get for nothing. Billing that tracks actual runs removes the entire cap-watching exercise, because there is no hard ceiling sitting on the meter whether you use it or not. Gravity takes the predictable version of this: the free tier at $0/month covers one agent, and paid plans start at $20/month with $20 of usage included, with the option to buy extra usage beyond your plan as you grow. The monthly number is known in advance rather than assembled from a meter at the end of the month.

The honest part is what it does for uneven work. A free tier punishes a busy week and wastes a quiet month, since the cap and the fee are both fixed. With pay-per-use, a quiet month costs almost nothing and a busy week costs only the runs you needed. You trade the comfort of a flat bill for spending that tracks real use, which suits anyone whose workload is lumpy rather than steady.

When a free tier still wins

To be fair, a free tier can be the right call. If your usage is small, steady, and sits comfortably inside the cap forever, free is genuinely free for you, and there is no reason to pay. The model only turns expensive when you outgrow the cap or your volume swings. The point is not that pay-per-use beats free everywhere; it is that you should price your own pattern before assuming free is cheapest.

Frequently asked questions

Do AI agent platforms have a free tier?

Most do, but not all, and they take different shapes. Checked 30 July 2026: MindStudio gives 1,000 runs per month on one agent, Gumloop gives 5,000 credits per month on one seat, Zapier gives 100 tasks per month on two-step Zaps, and Gravity gives a free tier covering one agent. Two exceptions matter: Lindy has no free plan at all, only a 7-day trial, and Relay.app is shutting down, with free accounts closing 15 August 2026. Each free tier caps something different, so check the vendor's current pricing page before comparing.

What is the best free AI agent platform?

There is no single winner, because each platform meters a different unit and you will hit whichever cap matches your workload first. On raw hosted allowance, MindStudio leads with 1,000 runs per month as of 30 July 2026. For multi-step automations across many apps, Gumloop's 5,000 monthly credits go further than Zapier's 100 tasks, though Zapier connects to far more services. For unlimited runs with no vendor cap, self-hosted n8n community edition is the only real option, paid for in hosting and maintenance rather than fees. Match the metered unit to your own workload rather than ranking the tiers against each other.

Is there a truly free AI agent platform?

Only self-hosted open source comes close. The n8n community edition has no license fee and no run cap, but you pay in hosting, setup time, model API calls, and maintenance. Every hosted free tier is free only up to a cap: 1,000 runs on MindStudio, 5,000 credits on Gumloop, 100 tasks on Zapier. So nothing capable is free without trade-offs, and the honest question is which cost you would rather carry, money or your own time.

What are the limits of free AI agent plans?

Caps on runs, credits, tasks, or steps per month, plus gated features, fewer connectors, and single-seat limits. Concrete examples checked 30 July 2026: Gumloop's free plan allows one active trigger and two concurrent runs, and Zapier's free plan limits every Zap to two steps regardless of task count. Many free plans also jump sharply at the first paid step, with Gumloop going from free to $37 per month. Read the limits before you build anything important on the plan.

Is a free tier or pay-per-use cheaper?

It depends on your volume. A free tier wins if your usage stays inside its caps forever. Pay-per-use wins when usage is uneven, because you pay only when an agent runs and carry no fixed monthly cost. Gravity takes a third path: a free tier that covers one agent, then subscription plans from $20/month that include $20 of usage, with more usage available as you grow.

Can you run AI agents for free?

You can run small experiments for free on chat tiers or self-hosted open-source tools. Running real, repeated work for free is rare, because runs cost compute and most platforms cap free usage. For occasional work, pay-per-use can be cheaper than a paid plan, since you pay only when an agent actually runs.
