Built for real work
Start in Slack. Run in parallel.
Run tasks side by side, start them from the tools you use, and bring your team.
Parallel tasks
Run many tasks at once.
Every task gets its own cloud sandbox, so they run side by side. Hand off five changes before lunch and review five pull requests after.
Integrations
Start in Slack or Linear.
Type /buildful in Slack, or label a Linear issue.
Shared memory
Learns as you merge.
Every merged pull request updates your team's memory and context, so each new task starts with what you've already shipped.
Team workspaces
Bring your team.
On Team, invite teammates to share repos, tasks and memory, and see what everyone is shipping.
Cloud
Cloudmaxxing.
Nothing runs on your laptop. Hand off the work, close the tab, and you're notified when it's done.
BYOK
Use your own keys.
On Pro or Team, pick a model and run it on your own OpenAI, Anthropic, Azure or xAI key.

One task, from the ask to the merged pull request.
Routed, built, checked and tested in a real browser.
Why it costs less
Superintelligence, routed.
Not every task needs a frontier model.
Every task runs on the open-weight model it needs: a fast one for small fixes, the most capable one for hard ones.
A typical task makes hundreds of model calls. Paying frontier prices for all of them is why AI plans cost $200.
Buildful picks the right open-weight model for each task, so $10 covers 1,000 of them. Frontier models like Claude and GPT are available whenever you need them.

questions
What is Buildful?
Buildful is an AI coding agent that works on your GitHub repo. You describe a new feature or a bug fix in plain words, and Buildful picks the right open-weight model for that task, writes the code in a private sandbox, runs your checks and opens a pull request. Pro is 1,000 tasks for $10 a month, about a cent a task.
How much does Buildful cost?
Pro is $10 a month for 1,000 tasks. Team is $40 a month for 3,000 tasks shared by unlimited teammates. On both, every included task runs on the open-weight model Buildful picks for it. You can also pick a frontier model yourself, like Claude or GPT, with prepaid credit, or bring your own API key.
Can I try Buildful for free?
Yes. Your first 3 tasks are free and need no card. They run on Smart Mode, with the same checks, browser test and pull request as the paid plans. When you want more, Pro is 1,000 tasks for $10 a month.
What's the difference between Pro and Team?
Both route every included task to the right open-weight model for you, and both let you pick a frontier model yourself, like Claude or GPT, with prepaid credit, or bring your own API key. On either plan you can add 1,000 tasks for $10 any time, and the Buildful Pass adds $80 of select models a month for $10. Team gives you 3,000 tasks a month instead of 1,000, plus unlimited teammates on one bill.
Is Claude Code free?
No. Claude Code comes with Claude's paid plans, Pro at $20 a month and Max from $100, or with pay-as-you-go API usage (checked October 2026). Buildful Pro is $10 a month for 1,000 tasks, and every task comes back as a tested pull request.
How much does Claude Code cost compared to Buildful?
Claude Code needs a paid Claude plan, from $20 a month for Pro to $100 and up for Max, or API credits. Buildful is $10 a month for 1,000 tasks, about a cent a task, with the right open-weight model picked for each task. On Pro or Team you can also pick Claude yourself, with prepaid credit or your own Anthropic key.
Is there a free Claude Code alternative?
You can try Buildful free: your first 3 tasks cost nothing and need no card. After that, Pro is 1,000 tasks for $10 a month, about a cent a task, with the right open-weight model picked for each task.
Is Buildful an AI code generator?
Yes. Describe a change and Buildful writes the code in your own GitHub repo, runs your checks, tests UI changes in a real browser, and opens a pull request for you to review and merge.
Is Buildful a vibe coding tool?
You describe changes in plain words, like vibe coding. What you get back is real code in your own GitHub repo: a pull request that has been checked, with UI changes tested in a real browser, which you review, then merge.
How is it different from Cursor, Lovable or Replit?
Cursor is an editor you code in, with cloud agents that bill by usage. Lovable and Replit build and host apps in their own workspace. Buildful takes a change you describe to your own GitHub repo and gives back a tested pull request, 1,000 tasks for $10 a month.
Can I choose Claude or GPT myself?
Yes, on Pro and Team. Pick a frontier model from Anthropic, OpenAI and others, like Claude or GPT, with prepaid credit, or bring your own API key. The tasks included in your plan run on the open-weight model Buildful picks for each one.
Can students use Buildful?
Yes. All you need is a GitHub account and a repo. Pro is $10 a month for 1,000 tasks, and every change comes back as a pull request you can read and learn from.
Do I need to know how to code?
No. Describe what you want in plain words. Each change arrives as a pull request, a change you review, then merge. Knowing some code helps you review it, but for UI changes you can watch the test recording either way.
