Start with GitHub Copilot Free if you want help inside an editor. Use Codex with GPT-5.6 Terra if you want an OpenAI coding agent on a Free or Go account. For a free API, Qwen 3.8 27B on Groq has the clearest published allowance. OpenRouter gives you more model choice, while NVIDIA lets you prototype with Kimi K3. None of these free routes is a production plan.
- GitHub Copilot Free includes 2,000 completions and 50 chat or agent requests per month.
- Amazon Q Developer Free includes 50 agentic requests per month in its IDE plugins and CLI.
- OpenAI gives Codex Free and Go users access to GPT-5.6 Terra.
- Groq's free plan gives Qwen 3.8 27B up to 30 requests per minute, 1,000 requests per day, and 200,000 tokens per day.
- OpenRouter lists more than 25 free models and limits a normal free account to 50 requests per day.
- NVIDIA lists Kimi K3 as a hosted trial service for prototyping.
- Replit Starter includes daily Agent credits and one free published app that expires after 30 days but can be republished.
- Cursor still has a free Hobby plan, but its current public page does not promise the old 2,000-completion and 50-request allowance used in the previous version of this article.
The April version of this article compared ten free tiers as if their limits stayed fixed. They did not. Copilot reopened paid upgrades, Replit replaced checkpoints with daily Agent credits, OpenAI brought GPT-5.6 Terra to free Codex users, and model hosts added better free APIs.
I removed any number I could not confirm on an official pricing or limit page. That leaves eight routes worth checking now.
Eight free routes compared
Pick an editor, an agent, or an API. They solve different problems.
Free access checked September 1, 2026
| Tool or route | What is free | Where it runs | The catch |
|---|---|---|---|
| GitHub Copilot Free | 2,000 completions and 50 chat or agent requests per month | VS Code, JetBrains, GitHub, CLI | The request allowance is small for daily agent work |
| Amazon Q Developer Free | 50 agentic requests per month | IDE plugins and CLI | A Builder ID or AWS identity is required |

Free help inside your editor
Copilot is the easiest start. Amazon Q gives you a separate monthly agent allowance.
GitHub Copilot Free
Copilot Free gives you 2,000 completions and 50 chat or agent requests each month. It works across the common editors, so you can install it without replacing your setup.
The earlier version of this article said paid Copilot upgrades were paused. GitHub's current pricing page offers Pro at $10 and Pro+ at $39, so that warning is gone. Free remains useful for autocomplete and occasional questions, but 50 agent requests will not carry a full month of daily repo work.
Amazon Q Developer Free
Amazon Q's current free tier includes 50 agentic requests per month across its IDE plugins and CLI. AWS defines an agentic request as either Q&A chat or an agentic coding interaction. The same tier includes 1,000 lines of Java transformation work per month.
Amazon Q makes more sense if you use AWS or want a second agent allowance beside Copilot. It requires an AWS identity or Builder ID, which is extra setup if none of your work touches AWS.
Cursor Hobby
Cursor still offers a free Hobby plan. I would use it to test Tab, Agent and the editor itself before buying Pro. I would not repeat the old 2,000-completion and 50-slow-request limits because Cursor's current public pricing material no longer promises those exact numbers. Check the usage dashboard attached to your account.
Free coding agents and model APIs
The useful new options are hosted models, not another autocomplete extension.
Codex with GPT-5.6 Terra
OpenAI's GPT-5.6 launch page says Free and Go users get Terra in ChatGPT Work and Codex. Paid plans can choose Sol, Terra or Luna. That gives you a real coding agent without paying on day one, although the account still has usage limits.
Qwen 3.8 27B on Groq
This is the cleanest free API option I found. Groq publishes the exact allowance: 30 requests per minute, 1,000 requests per day, 8,000 tokens per minute and 200,000 tokens per day. The model accepts text and images, supports tools and JSON, and runs at roughly 450 tokens per second on Groq.
Building on a tight budget? See the complete stack behind a live product.
Groq hosts a 131K context window with 16K maximum output. Paid usage is $0.80 input and $4 output per million tokens. The model is still marked Preview, so use it for prototypes, tests and low-risk internal tools before trusting it with production traffic.
Kimi K3 on NVIDIA
NVIDIA added Kimi K3 to its hosted model catalog on August 20. The model card describes a 2.8-trillion-parameter mixture-of-experts model with 104 billion active parameters, image input and a 1M-token context window. NVIDIA treats the hosted route as an API trial under its trial terms.
Use the trial to see whether K3 handles a long repo or document set better than the smaller free models. Do not design a production budget around a trial endpoint whose limits can change.
OpenRouter free models
OpenRouter lists more than 25 free models and exposes them through the same OpenAI-compatible API. You can choose a model ending in :free or send the request to openrouter/free and let the router select one.
A normal free account gets 50 free requests per day. That rises to 1,000 after purchasing at least $10 in credits, even when you continue using free models. The router can switch models between calls, so select a specific free model when repeatable behavior matters.
Privacy check
Free model hosts can use different inference providers with different data policies. Check the provider and logging settings before sending private code, customer data, keys, or production logs.
Free browser builder
Replit is useful for a small build, not an unlimited agent.
Replit Starter
Replit Starter now includes daily Agent credits up to a monthly cap, Lite build, a database and one published app. The deployment expires after 30 days, but you can publish it again. Full build, third-party connectors and additional published apps require Core or Pro.
The old article described ten one-time checkpoints and tiny fixed hardware limits. Those are no longer the current product description, so I removed them.
A useful $0 stack
Start small enough to learn what deserves money.
The setup
- 1Install Copilot Free for autocomplete and short questions inside your normal editor.
- 2Use Codex with GPT-5.6 Terra when the task needs repo-wide edits or terminal work.
- 3Create a Groq key and use Qwen 3.8 27B for your own scripts, prototypes, image input, or tool calls.
- 4Keep OpenRouter as a fallback when you want to compare several free models through one API.
- 5Try Kimi K3 on NVIDIA only for work where its long context could make a visible difference.
This setup costs nothing and covers autocomplete, an agent and an API. Do not install all eight products. Start with one editor tool and one API. Keep the one that survives a real week of work.
Where free stops working
The limit is not always a neat monthly number.
Copilot and Amazon Q cap requests. Groq caps requests and tokens. OpenRouter caps daily calls and can change the model behind its free router. NVIDIA calls Kimi a trial. Replit limits the build mode and deployment. Cursor's exact allowance belongs in the account dashboard instead of an old blog table.
Free access is enough for learning, a side project, a benchmark or the first version of an internal tool. It is a bad foundation for a customer-facing service that needs predictable latency, model availability, privacy terms and support.
When to pay
Pay when the limit interrupts work you already repeat. Copilot Pro is $10 per month. The common paid coding-agent tier starts around $20. Until the free limit blocks real work, keep the money.

FAQ
Which free AI coding tool is easiest to start with?
GitHub Copilot Free. It works inside common editors and includes 2,000 completions plus 50 chat or agent requests per month. If you want an API instead, start with Qwen 3.8 27B on Groq.
Can I use a capable AI model through an API for free?
Yes. Groq publishes a free allowance for Qwen 3.8 27B. OpenRouter offers more than 25 free models. NVIDIA has a Kimi K3 trial endpoint. All three are suited to learning and prototypes, not guaranteed production traffic.
Is GitHub Copilot still free in 2026?
Yes. Copilot Free includes 2,000 completions and 50 chat or agent requests each month. The old April warning about paid upgrades being paused is no longer current.
Can I code full-time using only free tools?
You can learn and build small projects. Daily agent work will eventually hit a request, token, speed or availability limit. Pay only after one of those limits interrupts a workflow you already use.
Does Claude Code have a free tier?
Claude Code is included with paid Claude plans and can also use API billing. For a no-cost terminal agent, Codex with GPT-5.6 Terra is the clearer official route for Free and Go users today.
