Free AI Coding Tools (2026)

Copilot Free is our first pick for trying code completion in an existing editor. Cursor Free suits an AI-editor trial, Antigravity CLI offers a quota-limited terminal agent, and ChatGPT Free provides limited Codex desktop access. OpenCode and Ollama are different: the software can be free while model hosting or hardware still costs money.

This ranking compares no-subscription starting points, not our overall paid-tool preferences. A useful free plan should let you finish and review a known task before you decide to pay.

Best Free AI Coding Tools

This ranks no-subscription starting points, distinguishing hosted free tiers from free software and local models. It is not our overall tool ranking. In the main ranking, Claude Code is our number-one pick, Cursor is second and Codex third, while Copilot sits well below them; a generous free tier does not change what we recommend paying for.

Tool	Type of Free Access	Main Limit or Cost	Best Fit
1. GitHub Copilot Free	Hosted free tier	2,000 completions monthly; separate limited chat/agent use	Current editor
2. Antigravity CLI	Hosted free tier	Basic weekly rate limits	Terminal agent trial
3. Cursor Free	Hosted free tier	Limited usage; check account allowance	AI editor trial
4. Codex	Hosted free tier	Limited Luna desktop use	Desktop task trial
5. OpenCode	Free agent software	Selected hosted models temporarily free; other providers may charge	Provider choice
6. Ollama	Local model runner	No per-request local fee; hardware and power costs remain	Local experiments

The ranking gives weight to a useful first hour, clear billing, and a path that doesn't require new hardware. It doesn't rank model intelligence from vendor tests. A free tier that lets you check one known task is more useful than a stronger model available only through a short trial or an unclear meter.

What Does “Free” Mean for AI Coding Tools?

Free AI coding tools offer either a hosted usage allowance, software you can run without a license fee, or local model execution without per-request charges. Those are different promises. A free agent can still call a paid model, and local inference still uses your hardware and electricity.

Copilot Free, Cursor Free, Antigravity’s free tier, and ChatGPT Free provide limited hosted access. OpenCode lets you choose a model provider, including selected free hosted models, while Ollama can run models locally. Check which arrangement applies before connecting a paid account.

Are Any Free AI Coding Tools Unlimited?

Local coding models can run without a hosted provider’s request quota, but their speed and capacity depend on your computer. The hosted free tiers in this shortlist have usage limits, and OpenCode’s selected free hosted models are temporary offers. Free software does not make a paid API unlimited or free.

GitHub Copilot Free for Editors

GitHub Copilot Free adds AI help to an editor you may already use. GitHub's individual-plan page lists up to 2,000 monthly code completions, plus limited chat and agent use through automatic model selection. No paid subscription is required for eligible individual accounts.

That offer works well as a test because the first task can stay familiar. Install Copilot in VS Code, Visual Studio, or a listed editor, then use it on code you already planned to write. Track which suggestions you accept and how much time you spend correcting them.

The limit covers evaluation and lighter personal work. Active daily typing can consume 2,000 suggestions before the month ends, while chat and agent work have their own allowance. Copilot tells you the reset date when you hit the plan limit, so the product itself should settle any dispute with an old article.

Copilot Free isn't designed as an enterprise plan. GitHub's documentation says it lacks organization controls such as audit logs, policy management, and file exclusion. A developer testing a personal repository and a company approving confidential code have different jobs. The free plan answers the first one.

Verified students should check GitHub's current Copilot Student eligibility page. Student access can include unlimited completions and a larger allowance than Copilot Free, but the account must remain verified and the current terms still apply.

Antigravity CLI for Terminal Work

Antigravity CLI is Google's terminal agent, sharing its agent harness with the Antigravity desktop app. It replaced Gemini CLI as the free consumer option on June 18, 2026, when Google stopped serving Gemini CLI to free, Google AI Pro, and Ultra users. Gemini CLI remains available through enterprise licenses and paid API keys. Antigravity CLI suits developers who already understand shell commands and repository diffs.

The free Individual tier costs $0 and provides quota-limited agent access. Editor completion features and terminal-agent model usage are different allowances. Google's current pricing page caps that tier with what it calls basic weekly rate limits and publishes no daily request count.

Because the cap resets weekly instead of daily, one heavy session can use a bigger share of the allowance than a Gemini CLI user would have noticed under the old daily counter. Watch the usage indicator during a repository task before assuming a full week of unattended work.

Cursor Free for an AI Editor

Cursor Free is the useful free option when the question is about Cursor itself. The editor combines Tab completion with an agent surface, and its VS Code roots reduce the move for developers who already know that editor family. Your files and many familiar extensions can stay in place during the trial.

Cursor's official pricing page promises limited Agent and Chat requests for Free. It doesn't publish a stable numeric ceiling there. The dashboard and in-editor warnings show the allowance tied to your account, which makes them safer than a number copied from an older comparison.

Don't turn the unpublished limit into a guess. Cursor has changed its usage model before, and the cost of an agent request depends on the work and model behind it. If the dashboard stops the same useful workflow across several weeks, then you have evidence for a paid-month test.

Codex on ChatGPT Free

Codex works in several apps and interfaces, but ChatGPT Free access is limited to Luna in the desktop app under the current plan. Do not assume the Free plan includes the CLI, editor extension, or cloud tasks. Start with one local task and a clear way to check the result.

OpenAI's current plan article covers how Codex draws on your ChatGPT plan's allowance. It doesn't promise a fixed message count. Usage varies with task size, how long the agent runs, and how much project context it must hold.

I use Codex as a second coding agent and as a reviewer, and scope matters more as the agent gets wider access. A task with named files and an exact check produces work you can assess. An open request produces activity that may have little to do with the result you wanted.

OpenCode and Ollama

OpenCode gives you a free agent program with a broad provider list. Its provider documentation says it works with more than 75 model providers, local models, OpenCode plans, and some existing subscriptions. Each connected provider brings its own billing rules and terms.

OpenCode also offers selected free hosted models. Its current model documentation lists Big Pickle, GLM-5.3-Flash Free, and DeepSeek V4.1 Flash Free, among others, as limited-time options. Select the explicitly free variant and check its availability and data terms; the similarly named paid model may still incur charges.

A paid API charges separately, an eligible subscription follows its own terms, and a local model uses your computer. Check the selected provider before treating the entire OpenCode setup as free.

Ollama's Free plan includes local model use, public models, and light cloud access. Ollama states that models running on your own hardware remain unlimited. Speed still depends on model size, computer memory, and hardware tuning.

Local use can keep code on the machine and remove per-request billing. It can also make a small laptop slow, limit which model fits, and turn setup into the main project. Start with a model that fits the hardware you already have. Buying a costly workstation to replace one small subscription puts hardware spending outside the free-tier budget.

Build a Useful Zero-Dollar Stack

A zero-dollar stack works best when each tool has one job. Use Copilot Free for inline suggestions in your current editor. Use Antigravity CLI for a bounded terminal task when you need an agent. Use the limited Codex desktop allowance for a second opinion or one bounded task.

That is enough variety to test completion, editor chat, and agent work without connecting a paid API. Add Cursor Free only when you want to test Cursor's editor. Add Ollama only when local execution answers a privacy, offline, or model-testing need.

Run the same small task in any tools you compare. Record the time spent setting up, reviewing the diff, and fixing mistakes. The output that looked fastest in a demo may lose once review time enters the count.

• Editor job: Copilot Free completes code you already planned.
• Terminal job: Antigravity CLI handles one bounded repository task.
• Second opinion: Codex reviews a short diff within the free desktop allowance.
• Local trial: Ollama runs a small model on existing hardware.

Do not connect four tools to the same repository on the first day. Start with one surface and one task, then add the second only when it answers a different question. Free software still costs attention, and setup time is part of the bill.

Know When Free Costs More

A free tier stops paying when the same limit breaks useful work across several weeks. One busy afternoon can still be misleading noise. A repeated reset wait during known tasks shows that the plan is now part of the job, and a paid month can test whether more capacity changes the outcome.

Review time also belongs in the final cost. An agent that writes a large patch in ten minutes may leave an hour of checking. A smaller completion tool can produce less code while keeping each accepted edit clear. Count finished, checked work instead of generated lines.

API access can erase the saving fastest. OpenCode and other provider-based agents make long model sessions easy to start, while the bill sits in another dashboard. Use a hard account cap, disable automatic reload, and check the meter after the first task.

Local models have a different cost curve. Existing hardware and a fitting model can make local use cheap. New high-memory hardware, extra setup, and slower output may cost more than a year of subscriptions. Privacy or offline access can justify that choice, but subscription avoidance alone often cannot.

Free AI Coding Tools Verdict

Copilot Free wins this free-tier ranking on a boring virtue: it publishes its code-completion allowance. Most free tiers make you discover the ceiling by hitting it, and a limit you can plan around beats a bigger allowance you can't verify. That is also the test to carry to any new free tool: if the vendor won't print the number, treat the tier as a demo, not a plan.

Use Codex's free desktop allowance when it covers the task, and check the usage meter before relying on it for a longer job. OpenCode is worth trying with a currently free model when you want provider choice; Ollama suits local work on hardware you already own. The beginner's AI coding guide covers the first task, while the open coding models guide covers the local path.

FAQ

What is the best free AI coding tool?

GitHub Copilot Free is our first pick for trying editor assistance at no cost; Cursor Free is an alternative for an AI-first editor, and Antigravity CLI is an option for terminal work. Check the current account allowance before a longer task.

Is GitHub Copilot Free really free?

Eligible individual developers can use Copilot Free without a paid plan. GitHub currently lists up to 2,000 monthly code completions plus limited chat and agent use through automatic model selection. The plan lacks the policy, audit, and management controls that paid organization plans provide.

Can I use an AI coding agent for free?

You can use a coding agent for free within a hosted plan’s allowance or with a suitable local model. Antigravity CLI offers quota-limited terminal work, Cursor Free has limited agent access, and ChatGPT Free provides limited Luna access in the Codex desktop app. Do not assume that Codex’s free desktop allowance includes its CLI, editor extension, or cloud tasks.

Is OpenCode free to use?

OpenCode is free software and offers selected free hosted models, but other model providers may charge. Its free hosted models can be limited-time offers; paid APIs, eligible subscriptions, and local models each have different costs and terms. Check the selected model and provider before starting a task.

Are local models cheaper than subscriptions?

Local coding models can be cheaper than subscriptions when your current computer runs the model well and you accept lower speed or a smaller model. Buying a new high-memory machine only to avoid one monthly plan can take years to repay. Local use makes more sense for privacy, offline work, or model testing.
