Learn to code free with hands-on lessons and instant playgrounds
Short, practice-first coding lessons that run directly in your browser, so you can start learning without installing a compiler or development environment.
Dedicated playgrounds for Python, JavaScript, C, C++, Java, SQL, React, Go, Swift and many other languages let you test snippets and experiment immediately after each lesson.
Structured curricula such as Software Engineer, Frontend, Full Stack, Backend, Data Analyst, Data Scientist, DevOps and game development bundle the skills employers actually ask for.
Streak-style daily coding challenges and progress tracking help learners build a consistent habit and stay motivated between longer courses.

Open-source control plane for orchestrating coding agents
Run Claude Code, Codex, Antigravity, OpenCode, Cursor and Grok sessions side by side in one workspace.
No resold tokens or quota caps — connect the credentials and plans you already pay for, and switch models mid-thread.
Manage branches, automate commits and pushes, and handle pull requests with inline diff review before accepting changes.
Open-source and MIT licensed, so you can run it on your own infrastructure and modify it for your team.

SpecialistWrite code with precision, hand bigger jobs to agents, and keep working from anywhere


Delivers structured data science and coding courses with interactive playgrounds, but focuses heavily on data analytics rather than general software engineering.

An agentic coding platform that ships real software

SpecialistTeaches computer science and logic through visual interactive puzzles and an AI tutor, but lacks traditional text-editor coding playgrounds.


SpecialistThe coding agent that learns your coding taste
SpecialistFocuses on hands-on browser-based Linux and DevOps labs with AI guidance, rather than general multi-language programming fundamentals.
Free / Open-sourceRuns multiple CLI coding agents in parallel using git worktrees, offering a robust open-source multi-agent developer environment.
Orchestrates parallel AI agents to plan and ship code, though with a different UI and workflow setup.

SpecialistKhan Academy's AI tutor and teaching assistant for guided, Socratic learning
SpecialistYour personal AI tutor — generate a course on anything in seconds
Acts as a collaborative control plane for local and cloud AI agents, sharing a strong multi-agent workflow focus.
