Pythagora vs Roo Code: How They Actually Differ
Roo Code fits a developer who lives in VS Code and wants an open-source, bring-your-own-key agent with multi-mode workflows and the freedom to inspect the code. Pythagora fits a builder who wants full-stack scaffolding — backend, database, and tests — generated in the browser without any local install.
Compiled 2026-08-27 from our catalogue entries for Pythagora and Roo Code.
The short answer
- Pick Roo Code if
- You use VS Code, want an open-source agent, and already have (or are willing to supply) your own API keys for Claude, GPT, or Gemini.
- Pick Pythagora if
- You want full-stack app scaffolding — backend, database, and tests — generated end-to-end in a browser with no local install, and a free tier to start on.
- Cheapest way in
- Roo Code is free to install and open-source, though you pay your LLM provider directly. Pythagora's starting price is not recorded, but it offers a free tier as part of its freemium model.
- What we could not compare
- Neither tool has verified plans on file, and neither lists docs. The specific starting price for Pythagora is not recorded, so a direct dollar-to-dollar comparison is not possible from the sheet.
Roo Code is an autonomous coding agent that runs as a VS Code extension. It is open-source, forked from Cline, and adds multi-mode workflows for different kinds of coding tasks. The extension uses a bring-your-own-key model across providers like Claude, GPT, and Gemini, so you decide which model and which account is billed. It is limited to VS Code — there is no JetBrains or other IDE extension — and you supply your own API keys rather than getting bundled inference.
Pythagora is a web-app builder agent that generates full-stack applications — backend, database, and tests — in a single workflow. It runs in the browser with no local install, operating as an autonomous agent that handles production-grade scaffolding end-to-end. Pricing is freemium, with a free tier to start, though that tier typically caps generated apps or sessions. It is web-only, with no local IDE or editor extension, and the underlying model is not self-hostable.

Where Pythagora is the better fit
- Generates full-stack web apps — backend, database, and tests — in a single workflow.
- Runs entirely in a web browser with no local installation required.
- Freemium pricing with a free tier available to start.
Where Roo Code is the better fit
- Released as open-source under a permissive license, with a public repo at github.com/RooCodeInc/Roo-Code.
- Runs as a VS Code extension and adds multi-mode workflows on top of the Cline fork.
- Supports bring-your-own-key for multiple LLM providers, including Claude, GPT, and Gemini.
Which one should you pick?
It is open-source, runs in the editor you already use, and lets you swap between modes and providers without leaving VS Code.
It produces a full-stack app — backend, database, and tests — in one workflow, runs in the browser, and has a free tier to start.
Frequently asked questions
- Does Roo Code actually cost anything?
- The extension itself is free and open-source under a permissive license, but you pay your LLM provider directly via the API keys you supply.
- Do I need to install anything to use Pythagora?
- No. It runs in a web browser with no local installation.
- Can I use Roo Code outside VS Code?
- No. The fact sheet lists it as limited to VS Code, with no JetBrains or other IDE extension available.
- What limits does Pythagora's free tier have?
- The sheet only states that the freemium tier 'typically imposes usage limits on generated apps or sessions.' Specific limits are not on file.

## Pythagora (/tools/pythagora) Tagline: Web-app builder agent that generates production-grade apps with backend, DB, and tests. Category: AI Coding Agents Pricing model: freemium Starts at: Not recorded Platforms: web Public repo: https://github.com/Pythagora-io/gpt-pilot Docs: none listed Verified plans: none on file Strengths on file: Generates full-stack web applications including backend, database, and tests in a single workflow.; Runs as an autonomous agent that handles production-grade app scaffolding end-to-end.; Accessible directly through a web browser without local installation.; Offers a free tier as part of its freemium pricing model. Limits on file: Freemium tier typically imposes usage limits on generated apps or sessions.; Generated output depends on the underlying model, which is not self-hostable. Pythagora is a web-app builder agent that generates full-stack applications — backend, database, and tests — in a single workflow. Its pitch is end-to-end scaffolding: an autonomous agent that handles the whole build and runs entirely in the browser, with no local install. It's for people who want a full app scaffolded without setting up a local environment, with a free tier to start. Two limits: it's web-only — no local IDE or editor extension — and the freemium tier caps generated apps or sessions. It's a browser-based, generate-the-whole-app agent, next to the CLI scaffolder smol developer and distinct from the in-editor coding agents. ## Roo Code (/tools/roo-code) Tagline: Open-source autonomous coding agent for VS Code, forked from Cline with multi-mode workflows. Category: AI Coding Agents Pricing model: free Starts at: Free Platforms: vscode-ext Public repo: https://github.com/RooCodeInc/Roo-Code Docs: none listed Verified plans: none on file Strengths on file: Open-source AI coding agent released under a permissive license.; Runs as a VS Code extension that integrates directly with the editor.; Forked from Cline while adding multi-mode workflows for different coding tasks.; Supports bring-your-own-key for multiple LLM providers including Claude, GPT, and Gemini. Limits on file: Limited to VS Code with no JetBrains or other IDE extension available.; Requires users to supply their own API keys rather than bundling inference. Roo Code is an open-source autonomous coding agent for VS Code, forked from Cline and adding multi-mode workflows for different kinds of coding tasks. Its angle is flexibility and openness: a permissively licensed VS Code extension with bring-your-own-key across providers like Claude, GPT, and Gemini, and modes you switch between for different jobs. It's for VS Code users who want Cline's inspectable, open approach with more workflow structure. Two limits: it's VS Code only — no JetBrains or other IDE extension — and you supply your own API keys rather than getting bundled inference. It's the multi-mode fork of Cline, in the same open, BYOK, in-VS-Code lane.
