# Headstarter — Full Documentation > Headstarter (www.headstarter.co) is the agentic engineering platform. Work across repos, talk to your code, and let AI agents ship PRs for you. 1,000+ engineers from Google, Microsoft, Meta, Amazon, Apple, JPMorgan, Adobe, Stanford, Harvard, CMU, Waterloo, and Toronto. Members have been accepted to Y Combinator, raised $4.5M in funding, and sold companies to YC startups. ## Community URL: https://www.headstarter.co/network Headstarter is building the #1 community for software engineers. Members prove their skills by building real projects with AI-native tools. - 15,000+ software engineers from companies like OpenAI, Perplexity, Google, etc. - Members work at Google, Microsoft, Meta, Amazon, Apple, JPMorgan, Capital One, Adobe, and more - Universities include Stanford, Harvard, CMU, UT Austin, UIUC, Waterloo, and Toronto - 79% have completed multiple software engineering internships - Members have been accepted to Y Combinator, raised $4.5M in funding, and sold companies to YC startups - Searchable directory by company, university, or location URL: https://www.headstarter.co/about Founded by Yasin Ehsan & Faizan Ahmed. Through building in public, getting off localhost, and working on real-world problems, the community has produced YC acceptance, venture funding, and acquisitions. --- ## Headstarter Agent URL: https://www.headstarter.co/repo Connect any GitHub repository and work with an AI coding agent that reads, edits, and ships code for you — in any language, any framework. ### Talk to Your Code Real-time voice AI mentor that guides you through debugging, architecture decisions, and code reviews. Uses Socratic questioning so you learn while you build. Tracks your live code changes and adapts the conversation in real time. ### Agentic Code Editing The agent reads files, makes edits, creates new files, searches your codebase, runs shell commands, and validates its own work. If something breaks, it self-corrects. Works with JavaScript, TypeScript, Python, Go, Rust, Java, and more. ### One-Click GitHub Create pull requests or commit directly to any branch from the browser. Auto-generated commit messages and PR descriptions. ### System Design Diagrams Auto-generate architecture diagrams from your codebase showing component dependencies and data flow. Edit the diagram and the agent writes the corresponding code. --- ## Multi-Project Workspace URL: https://www.headstarter.co/workspace Open multiple GitHub repos in one browser tab and let an AI agent coordinate changes across all of them at once. - **Split View**: Edit two projects side-by-side. Switch between repos with keyboard shortcuts. - **Workspace Agent**: A single AI agent that sees all your projects and makes cross-repo changes in one conversation — sync types, add features, fix tests across services. - **Floating Agent Panel**: Detach the agent panel, drag it anywhere, and prompt it while you browse code. @-mention files from any project. - **Project Tabs**: Each repo is a tab with status indicators. Add repos from GitHub or by URL. - **Activity Feed**: Real-time log of edits, commits, and PRs across all projects. --- ## Autonomous Build Agent URL: https://www.headstarter.co/replay Give it an idea and the agent builds a complete full-stack application from scratch — architecture, code, deployment, and quality validation — all autonomously. - **Idea to Deployed App**: The agent generates the architecture, writes all the code, deploys to a live URL, and validates the result in a real browser. - **Quality Iteration**: After deployment, the agent screenshots the live app, scores it on design, layout, content, and functionality, and iterates with fixes until it meets quality standards. - **Full Replay**: Every decision, file edit, command, and commit is logged. Replay the entire build to learn from the agent's architecture and coding decisions. - **Delivered Artifacts**: Every build produces a GitHub repository with full commit history and a live deployed URL. - **Idea Generation**: Generates project ideas across 30+ categories by combining free public APIs into data-rich applications. --- ## Developer Tools ### ProfileRank URL: https://www.headstarter.co/rank AI-powered skill scoring that analyzes your LinkedIn and GitHub profiles. Get scored across technical skills, experience, education, activity, and projects with an S/A/B/C/D tier grade. Includes per-repository quality analysis with complexity, completeness, and originality scores. ### Browser-Based IDE Full VS Code editor (Monaco) in the browser with syntax highlighting, IntelliSense, real-time diagnostics, and Tokyo Night theme. ### Code Execution Run Node.js directly in the browser with StackBlitz WebContainers, or spin up cloud sandboxes for Python and multi-language projects with E2B. ### Interactive System Design Draw architecture diagrams with Excalidraw, and the AI understands the components, connections, and data flow to generate or modify code. --- ## Workshops URL: https://www.headstarter.co/workshops Hands-on workshop series where you build real AI systems with step-by-step video tutorials and interactive Jupyter notebooks. ### Build Your Own GPT Model Follow Andrej Karpathy's Neural Networks: Zero to Hero course. Each lecture is a self-contained Jupyter notebook you can run directly in the browser. - **Lecture 1 — Micrograd & Backpropagation**: Build an autograd engine from scratch. Covers derivatives, computation graphs, the chain rule, and training a multi-layer perceptron. - **Lecture 2 — Bigram Language Model**: Build a character-level language model. Covers bigram statistics, maximum likelihood estimation, softmax, and next-character prediction. - **Lecture 3 — Word Embeddings & MLPs**: Build a GPT model from scratch using character-level bigram, trigram, and MLP models. Covers word embeddings, cross-entropy loss, and hyperparameter tuning. --- ## Blog URL: https://www.headstarter.co/blog - [Prompts Are the New Architecture Decisions](https://www.headstarter.co/blog/prompts-are-the-new-architecture-decisions) — The 5-step framework for shipping production code with AI agents. - [True Alpha Lives in the Agent Harness](https://www.headstarter.co/blog/true-alpha-lives-in-the-agent-harness) — Why the infrastructure wrapping the LLM matters more than the model itself. - [The Last Line of Code](https://www.headstarter.co/blog/the-last-line-of-code) — The future of engineering is orchestrating agents. - [The End of Next-Token Prediction](https://www.headstarter.co/blog/the-end-of-next-token-prediction) — How diffusion-based language models are changing code generation. - [Death by a Thousand Handshakes](https://www.headstarter.co/blog/death-by-a-thousand-handshakes) — Why persistent connections cut AI agent latency in half. - [Draw Your Architecture, Ship Your Code](https://www.headstarter.co/blog/draw-your-architecture-ship-your-code) — Turn architecture diagrams into working code. - [1 Year in AI is 7 on the Internet](https://www.headstarter.co/blog/one-year-in-ai-is-seven-on-the-internet) — Field report from Stanford, Harvard, CMU, Waterloo, and Toronto. --- ## Links - Homepage: https://www.headstarter.co - Network: https://www.headstarter.co/network - About: https://www.headstarter.co/about - Blog: https://www.headstarter.co/blog - Workshops: https://www.headstarter.co/workshops - X / Twitter: https://x.com/faizan_a1 - Privacy Policy: https://www.headstarter.co/privacy-policy - Terms of Service: https://www.headstarter.co/terms-of-service
