GoCodeo

GoCodeo's app builder turns a framework choice into a ready-to-code workspace. It generates the file structure and config for more than 25 frontend and backend frameworks, so a new project starts with the layout already in place. For developers who lose an afternoon to setup, that's the feature they notice first.

The core agent writes code that runs, not just snippets. You describe a feature in plain language, or attach an image and let the "Use Image" option generate a project structure from it, and GoCodeo produces the files and configs to match. An "Enhance Prompt" step expands a rough idea into a fuller spec with functional and technical detail before the code is written.

GoCodeo connects the backend and ships the frontend in a single step. It auto-connects to Supabase, generates the backend code and deploys to Vercel, with no separate setup pass. For a solo builder, that replaces a string of manual steps that usually involve copying API keys between dashboards.

Through the Model Context Protocol, GoCodeo plugs into more than 100 tools, including GitHub, Notion, Stripe and Perplexity. The agent can fetch live context, raise pull requests, seed databases or run end-to-end workflows inside your existing setup. That breadth is what separates it from extensions that only edit files.

The extension handles testing end to end. Chapter-level features let you generate tests, run them through the built-in test runner, regenerate or expand them, and have AI diagnose failing cases with fixes tied to your code and framework. You can also set the code style, test framework and number of tests per run, so the output matches how your team already works.

GoCodeo gives you a model selector rather than locking you to one provider. You can reach models from OpenAI, Anthropic's Claude, Google Gemini and DeepSeek, and switch between them per task. Premium models like GPT-4o and Claude Sonnet sit behind paid plans, while basic models stay open on the free tier.

You can point the agent at your own code with the @ symbol, which lists files and code symbols in your folder, and pull in outside answers with the @Web search feature. That search is powered by Perplexity and auto-writes queries based on your code, so the references and docs it returns relate to what you're building.

GoCodeo scans your repo and generates a structured README.md or PRD saved to the root directory, which saves the write-up work most developers put off. It also automates repo initialization, commit management and pull request creation, giving you a link to share right after.
