Pythagora

Pythagora is an AI development platform (home of GPT Pilot) that builds production-ready apps with you through structured, step-by-step agent workflows.

Overview

Pythagora grew out of GPT Pilot, one of the earliest open-source AI developer agents, and turns app development into a structured conversation: the agent interviews you about requirements, drafts a plan, writes code file by file, runs tests and debugs its own output. Rather than a one-shot generator, it works like a developer you supervise — each milestone is reviewable, and you can steer architecture decisions as the codebase grows. The result is meant to be real, editable code in your own repository, not a black-box prototype.

A build session begins with the agent interviewing you about users, constraints and stack preferences, then proposing a milestone plan you approve before code is written. Each milestone ends with runnable software and tests, so drift is caught early rather than after weeks of generation. Developers keep ownership throughout: the output is a conventional repository you can open in any editor, and the open-source GPT Pilot core means self-hosters can run the same pipeline with their own model keys.

Key Features

• Requirement interviews that convert vague ideas into implementable specs
• Milestone-based development with human review at each stage
• Self-debugging loop: the agent runs code, reads errors and fixes them
• Test generation and execution as part of the build process
• Output is standard code in your own repo, ready for manual editing
• Open-source roots (GPT Pilot) with a hosted platform on top
• Milestone gating with human approval before each build phase
• Self-debugging loop that runs and repairs generated code

Pricing

Pythagora offers a free trial with starter build credits and paid plans metered by development hours or agent usage. The underlying GPT Pilot project remains open source for self-hosting with your own model API keys.

Who Is It For

It suits developers and technical founders who want an AI agent to handle scaffolding and boilerplate while keeping full ownership and understanding of the resulting codebase.

FAQ

Is Pythagora free to use?

The open-source GPT Pilot is free to run with your own API keys; the hosted Pythagora platform offers limited free usage then paid build credits.

Does Pythagora offer an API?

Pythagora is primarily an interactive development environment; automation is available through the CLI and the open-source project.

How does Pythagora compare to alternatives?

Compared with one-shot app generators, Pythagora’s milestone structure produces codebases that are easier to understand and extend, at the cost of a slower, more deliberate workflow.

What tech stacks can Pythagora build?

Pythagora targets common web application stacks — typically JavaScript/Node-based front ends and back ends with databases — and continues to expand framework support on its hosted platform.
