Best free AI for coding projects: work within 30 monthly build credits
Answer in brief
Our best free AI for coding projects workflow pairs editor assistance with a free coding chatbot; Lovable adds app building with five daily build credits, capped at 30 per calendar month. Use Copilot, Cursor or Windsurf only within their current allowances. Keep a small project scope, review generated changes, and run your own tests before deployment.

The existing coding category compares assistants. This guide instead follows a small project from a written requirement to a tested change. The broad 'best free AI for coding' query stays with that comparison; this page covers project workflow and budgeting, not a second ranking of the same tools.

|---|---|---|

| Build an appOfficial source | Lovable: 5 daily build credits, capped at 30/month | Build and chat allowances are separate |

| Debug a failureOfficial source | DeepSeek consumer chat | API billing isn't included in free chat |
Tools for each part of the task
GitHub Copilot Free
Assistance inside your editorUse completions for a contained function, then inspect the code. Chat and agent usage have separate limits; confirm the current plan before planning long sessions.
- Code completions in supported editors
- Chat and agent usage is capped; check GitHub's plan page for the current number
DeepSeek
Explain or debug a small exampleShare a minimal reproducible example rather than private repository contents. Consumer chat is free, while developer API calls are billed separately.
- Free consumer chat, per DeepSeek's app announcement
- No published usage numbers; the app can slow down at busy times
Lovable
Build an app from a written requirementKeep the first task small enough for the five-daily, 30-monthly build grant. Our real invite link is sponsored; the referral doesn't change those recurring limits.
- Build and publish apps and websites by chat
- Daily build credits stop after the 30-credit monthly cap and resume next calendar month
Referral bonus: 10 bonus credits when you sign up through this invite link, on top of the free plan (per Lovable's referral program). Code: IWPF5ET. Referral link; see our disclosure.
Cursor
Try an agent-assisted repository changeFree editor usage is limited. Current subscriptions differ from legacy Hobby and Pro; check the account's actual plan.
- Limited AI usage in the editor
- Cursor doesn't publish a number for free usage
Windsurf
Compare another editorTry the editor, but don't budget around an unverified completion or agent quota. Our available source currently describes Devin rather than a Windsurf-specific allowance.
- Free editor access; confirm current Windsurf-specific allowances
- Limited model choice
Build one complete slice before adding another
For a task tracker, start with adding and completing one task, including invalid input and refresh behavior. Write down what should persist before asking an assistant to generate code. This is an example project method, not a promise that a given credit balance finishes an app.
Inspect changes before accepting them. Run tests for the behavior you requested and try the form with empty and messy input. A screenshot of the happy path doesn't establish data persistence or permissions.
Stop before the allowance becomes the project plan
Track the allowance remaining after each meaningful change. The Lovable daily grant stops at the calendar-month cap; switching between tools doesn't convert their credits into a shared balance.
Use version control and keep a known working revision. When a generated fix fails repeatedly, reproduce the error and narrow the task instead of asking for another broad rewrite. Review data access and deployment settings before sharing the app.
When to stay free
- You're learning or building a small slice and can wait for allowance resets.
- You can review and test the generated code rather than handing off the whole project.
When to consider upgrading
- A verified usage restriction blocks the next defined slice of work.
- You need a specific paid deployment or collaboration feature and have checked its terms.
How these recommendations are made
We compare official plan terms with the task described, not invented benchmark results. Unconfirmed allowances stay qualified. Referral links are marked sponsored and don't establish product quality. Read our methodology and affiliate disclosure.
Questions before choosing a plan
What is the best free AI for coding projects with 30 monthly build credits?
Lovable's free build grant is five daily credits capped at 30 per calendar month. Pair it with review and tests; the balance doesn't guarantee a particular app will be finished.
Where is the general coding-assistant comparison?
The coding category guide compares tools by editor support and task. This guide covers building and checking a small project.
Does free DeepSeek chat include API access?
No. Developer API usage is billed separately from the free consumer chat app.
