Every one of these tools will tell you it's free. What they won't tell you is how fast that "free" runs out — and what happens when it does.
, Cursor, and Trae are the three most-talked-about AI IDEs for people just getting started with vibe coding. They all sit on top of VS Code. They all promise AI that writes code alongside you. And they all have a free tier. But the experience of actually using each one for free is very different, and for a beginner that difference matters more than any benchmark.
This comparison has one lens: can you use this tool for free without hitting a wall in week one?
The free tier problem: not all "free" AI IDEs are equal
What counts as "free" in 2026
There are two kinds of free in this space. The first is a time-limited trial — you get full Pro features for a week or two, then you're cut down to a much thinner plan. The second is a sustained free tier — limited in some ways, but usable indefinitely. Knowing which kind you're signing up for changes everything about how you evaluate a tool.
In 2026, leans on the first model. Windsurf and Trae lean on the second, though Trae's free tier went through significant changes in early 2026.
The three contenders at a glance
| | Windsurf | Cursor | | |---|---|---|---| | Free autocomplete | Unlimited Tab | Limited (Hobby) | 5,000 completions/month | | Free AI chat/agent | 5 Cascade sessions/day | 2-week Pro trial, then Hobby | Token-based free allowance | | Top model on free | GPT-4o / Sonnet (limited) | GPT-4o (limited) | Claude Sonnet (limited) | | Setup complexity | Low | Low | Low | | Platform | Windows, Mac, Linux | Windows, Mac, Linux | Windows, Mac only |
Windsurf free tier — what you actually get
Free autocomplete: unlimited vs. limited
Windsurf's biggest free-tier advantage is Tab autocomplete — it is unlimited on the free plan. That means line completions, multi-line suggestions, and next-edit predictions keep working no matter how long you use it. For someone spending most of their time writing code rather than chatting with an AI agent, this is genuinely useful every day.
Unlimited Tab is the headline. Most competing IDEs put autocomplete behind a credit counter or a monthly cap.
Cascade (the agentic feature) on the free plan
Cascade is Windsurf's multi-step agent — you give it a goal, it plans and executes across multiple files. On the free plan, Cascade is credit-limited. Once your monthly credits run out, you either wait for the month to reset or upgrade.
As of March 2026, Windsurf retired its credit system and moved to a refreshing usage quota: the free plan includes 5 Cascade sessions per day. For casual use, that's enough to experiment. For anyone using it daily to build something real, you'll probably notice the ceiling within a session or two.
Who Windsurf free is right for
Windsurf free is the best pick if autocomplete is your main use case and you treat the agent as a bonus. It's also a smart choice if you're likely to upgrade eventually — the paid plan ($20/month) is competitive, and the free-to-paid transition is seamless. Read our full Windsurf review for a deeper look at the overall product.
Cursor free tier — what you actually get
2-week Pro trial, then what?
Cursor opens with a 14-day Pro trial. During that window you get access to premium models, the full Composer and Agent experience, and everything that makes Cursor interesting. It's a good two weeks — and it's specifically designed to let you build a habit before the limits kick in.
When the trial ends, you drop to the Hobby plan.
Hobby plan limits and model access
The Cursor Hobby plan keeps the editor itself — syntax highlighting, the VS Code shell, extensions — but AI features become heavily limited. You get 2,000 completions and 50 slow premium requests per month.
Cursor 3 (released April 2026) introduced significant new features: an Agents Window, Design Mode, and the Composer 2 frontier model running at 200+ tokens/second. All of these — parallel agents, Design Mode, Composer 2, cloud execution, and built-in Git — are Pro-only. Hobby stays at 2,000 completions and 50 slow premium requests.
The practical reality: Cursor free after the trial is underwhelming for someone who got a taste of the Pro experience. It's usable, but you'll feel the gap.
Who Cursor free is right for
Cursor free (really: the Cursor trial) makes sense if you're already living in VS Code and want to test an AI IDE before committing to anything. The two-week window is genuinely enough time to decide whether AI-assisted coding is something you want. If you're comparing Cursor and Trae more directly, see Trae vs Cursor 2026.
Trae free tier — what you actually get
Why Trae is the most aggressive free offering right now
Trae launched in late 2024 as a genuinely unlimited free product — no caps on completions, no credit system, full model access. That changed in February 2026 when ByteDance moved Trae to a token-based pricing model with paid tiers starting at $3/month.
Even after that shift, Trae's free tier remained more generous than Cursor's Hobby plan — 5,000 auto-completions per month, plus 10 fast and 50 slow premium model requests.
Builder Mode and Claude Sonnet access on free
Trae's standout feature is Builder Mode — an agentic mode that handles multi-step tasks, runs a built-in web preview inside the editor, and even includes a UI/UX screenshot-to-CSS agent. This is genuinely differentiated from what Windsurf and Cursor offer at the same price point (free).
Access to Claude Sonnet on the free tier — even in a limited form — is notable. Most tools reserve frontier model access for paid plans. This held true through the February 2026 pricing restructure: Builder Mode and Claude Sonnet remain available to free users within the monthly request allowance.
The catch: ByteDance, data, and trust questions
Trae is built by ByteDance, the same company behind TikTok. For many users this is a non-issue. For others — particularly those working on anything proprietary, client work, or anything they'd rather not have processed on ByteDance infrastructure — it's a real concern worth thinking through before you use it.
The trust question isn't unique to Trae (every cloud IDE sends your code somewhere), but ByteDance's geopolitical profile makes it more salient here. Read our full Trae review for a detailed breakdown of the data and privacy considerations.
Who Trae free is right for
Trae free is the right call if you want the most AI capability for the least money and the ByteDance question doesn't concern you. Builder Mode alone — available to free users — is a feature that competing IDEs charge for.
Head-to-head: the free tier breakdown
Feature comparison table
| Feature | Windsurf Free | Cursor Hobby | Trae Free | |---|---|---|---| | Autocomplete | Unlimited Tab | 2,000/month | 5,000/month | | AI chat | 5 Cascade sessions/day | 50 slow premium requests/month | 10 fast + 50 slow requests/month | | Agent / agentic mode | 5 Cascade sessions/day | Very limited post-trial | Builder Mode (within request allowance) | | Top model available | GPT-4o / Sonnet (rationed) | GPT-4o (limited) | Claude Sonnet (limited) | | In-editor preview | No | No | Yes | | Linux support | Yes | Yes | No | | VS Code compatible | No (own fork) | No (own fork) | Yes (full VS Code) |
Speed and quality on a simple vibe coding task
For a simple vibe coding task — "build me a landing page with a form that submits to an email" — all three tools can get you there on their free plans. The differences show up in how many interactions it takes and whether the agent runs out of credits midway.
Windsurf tends to be reliable on straightforward tasks with good autocomplete filling in the gaps. Cursor's free tier will struggle with multi-step tasks after the trial ends. Trae's Builder Mode often handles the full task end-to-end, including the preview — when credits allow.

Which free AI IDE should you start with?
If you want the most AI power for free right now: Trae
Trae's free tier — even after the February 2026 changes — gives you more agentic capability than either alternative at no cost. Builder Mode, in-editor preview, and access to frontier models on the free plan are genuinely hard to match. The trade-off is the ByteDance data question and Windows/Mac-only support.
If you plan to pay eventually and want to test first: Windsurf
Windsurf's free tier is the most sustainable long-term free experience. Unlimited autocomplete keeps the tool useful every day, and if you decide to upgrade, you're already familiar with the product. Use the trial period to evaluate Cascade properly, then decide. Try Windsurf
If you're already in VS Code and just want to try: Cursor trial
The Cursor 14-day Pro trial is one of the best ways to experience what a fully-featured AI IDE feels like. If you're curious about the category but not ready to pick a tool, start here — just know that the free experience after the trial is significantly weaker.

From the comments

Honest question since all three have free ceilings: could you just run all three side by side and bounce between them to never pay anything? Or is that a recipe for chaos?
You technically could, since the free tiers reset on different schedules — Windsurf's is 5 Cascade sessions per day, Trae's is a monthly request allowance, and Cursor's real value is the one-time 14-day trial. But the article's framing is the honest one: the question is whether you hit a wall in week one, not how many accounts you can juggle. Windsurf's unlimited Tab is the one piece that stays useful indefinitely without rationing.
So Cursor is the odd one out cost-wise — once that trial's gone it's basically a habit you've paid for?
That's close to how the article puts it. The trial is described as specifically designed to build a habit before the limits kick in, and after it you drop to Hobby — 2,000 completions and 50 slow premium requests a month, with the Cursor 3 features like parallel agents and Composer 2 all Pro-only. The piece calls the post-trial free experience underwhelming for anyone who got a taste of Pro.
None of these are open source or self-hostable, right? The piece says every cloud IDE sends your code somewhere. Is there a free option here that keeps the code on my machine?
Not among these three — the article treats all of them as cloud IDEs and explicitly says every cloud IDE sends your code somewhere. It doesn't cover any self-hosted or open-source alternative, so I can't point you to one from this piece. What it does flag is the trust dimension: Trae is built by ByteDance, and the article says that's a real concern worth thinking through for proprietary or client work, even though the send-your-code-somewhere issue isn't unique to Trae.
And two of them aren't even real VS Code, so I can't bring my own setup?
Per the comparison table, Windsurf and Cursor are their own forks rather than full VS Code, while Trae is listed as fully VS Code compatible. So of the three, Trae is the one that lines up with a standard VS Code setup.
Taking notes here. If I start free on one of these and outgrow it, how locked in am I? Like can I move to another tool later without redoing everything?
The article doesn't walk through migrating between them, so I'd be guessing on the mechanics. What it does note is relevant though: Windsurf and Cursor each run their own fork, while Trae is full VS Code compatible. A standard VS Code base generally means your extensions and config travel more easily, which is worth weighing if portability matters to you early on.
Got it. And which one's least likely to box me in on what I can build for free while I'm learning?
For learning specifically, the article's split is useful: Windsurf gives you unlimited Tab autocomplete that stays useful every day, while Trae's free tier is called the most generous for agentic work — Builder Mode and limited Claude Sonnet access included free. Cursor's strength is the 14-day Pro trial to feel the full experience, but it weakens a lot after that. So if you want something that doesn't ration the everyday writing, Windsurf's autocomplete is the piece that keeps working without a counter.
