Best Free AI Coding Assistants

How we picked

We picked based on what's actually free — not a trial that expires, but a tier you can use indefinitely without a credit card — and cross-checked pricing directly against each vendor's published plans. GitHub Copilot's Free tier and Cursor's Hobby tier both qualify: Copilot Free gives 2,000 completions per month plus limited chat and agent usage, and Cursor Hobby is free with no credit card required, though Agent requests are limited.

We didn't include tools we can't verify pricing for. A lot of "best free AI coding assistant" roundups pad the list with five or six names and a price for each, but if we haven't checked a vendor's current pricing page ourselves, we're not going to state a number for it. That leaves two options here, both fully documented, rather than a longer list built on secondhand figures.

The shortlist

Two tools make this shortlist because they're the ones with pricing we've verified directly: GitHub Copilot for inline completions inside your current editor, and Cursor for agentic, multi-file editing in a standalone one. Each free tier serves a genuinely different workflow, so the right pick depends on which kind of assistance you actually need day to day.

GitHub Copilot's Free tier runs as a plugin inside VS Code, JetBrains IDEs, Visual Studio, and the GitHub site, so there's zero migration cost to try it — you install it in the editor you already use. The 2,000-completions-per-month cap is generous enough for regular use by most individual developers, and it's free outright for verified students, teachers, and maintainers of popular open source projects, which removes the cap entirely for those groups.

Cursor's Hobby tier takes a different shape: it's a standalone editor forked from VS Code, so your existing extensions and keybindings carry over, but you are working inside a new application rather than a plugin. What you get in exchange is agent mode that makes multi-file edits across the whole repository, which is a materially different capability than Copilot's completions — Agent requests are limited on Hobby, but the feature itself is the real one used on paid Cursor plans, just capped.

Neither of these free tiers includes MCP, skills, hooks, cloud agents, or Bugbot code review at meaningful scale — those live on Cursor's paid tiers — and Copilot's free chat and agent usage draws from the same limited allowance as its completions, so heavy chat use eats into what's available for the month.

It's also worth running both at the same time rather than picking one and committing. Because Copilot installs as a plugin and Cursor is a separate editor, there's no real conflict in trying both on the same machine over a couple of weeks — you can keep your current IDE with Copilot active for everyday completions while spinning up Cursor on a side project to see whether agentic multi-file editing actually changes how you work. Most developers land on a clear preference within a few real coding sessions, faster than any spec comparison will tell you, and that preference tends to stick once formed.

One more distinction worth naming: Copilot's free and Pro tiers price by feature (completions unlimited on Pro, credits for chat and agents), while Cursor's free and Pro tiers price by request volume against one unified agent experience. That means the two tools don't map onto each other cleanly even at similar price points once you're comparing paid plans, so a straight dollar-for-dollar comparison between Copilot Pro at $10/mo and Cursor Pro at $20/mo undersells how differently each one spends that money, and is a reason to trial both rather than pick by price alone.

What to watch out for

The biggest thing to watch for is mistaking a limited free tier for an unlimited one. Copilot's Free plan caps completions at 2,000 per month, and once you're past that, suggestions stop until the next billing cycle — that's plenty for light or exploratory use but tight for someone coding full time. Cursor's Hobby tier similarly limits Agent requests, so if you're running agentic, multi-file edits regularly, you'll hit that ceiling faster than you'd expect from a single afternoon of real work.

Also watch the migration cost if you're testing Cursor: it's a separate editor, not a plugin, so you're evaluating a new application, not adding a feature to your current one. That's a bigger commitment than installing a Copilot extension, even though Cursor's VS Code lineage makes the switch smoother than adopting a truly unfamiliar tool. If you decide the agent-first model is worth it, our Cursor vs GitHub Copilot comparison covers the full pricing ladder on both sides once you're ready to pay.

Finally, don't assume free means risk-free from a workflow standpoint. If you build a habit around Copilot's Free tier and then hit the 2,000-completion wall mid-project, or you get used to Cursor's agent mode on Hobby and then need more Agent requests than the free allowance provides, you'll be making a paid-tier decision under time pressure. It's worth testing both free tiers early, understanding where their limits sit, and deciding in advance which paid tier — Copilot Pro at $10/mo or Cursor Pro at $20/mo — you'd upgrade to before you actually need it, rather than scrambling to compare pricing pages mid-deadline. If you want a broader set of paid options once you outgrow the free tiers, our Cursor alternatives roundup and Claude Code vs Cursor comparison are both good next reads, and Cursor vs Windsurf is worth a look if you're specifically weighing agent-first editors against each other rather than an editor-versus-plugin decision.
