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.

An agentic analytics platform that turns questions into governed, trusted answers
Ask a question in plain language and get a reasoned answer with the SQL, charts and tables behind it, available in the Hex workspace, in Slack and from developer tools.
Write SQL, Python and R side by side in one project, then turn cells into interactive, parameterised data apps and dashboards without a separate BI authoring tool.
Centralise metrics, semantics and corporate definitions so answers stay consistent, and see exactly where the agent lacked grounding so you can fix it.
Run graded, rubric-based test suites against the agent to measure answer quality and catch regressions as your data and context evolve.

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

SpecialistFocuses on hands-on browser-based Linux and DevOps labs with AI guidance, rather than general multi-language programming fundamentals.
Faster for ad hoc statistical analysis and data visualization from natural language, but lacks Hex's robust notebook workflows.

SpecialistKhan Academy's AI tutor and teaching assistant for guided, Socratic learning

SpecialistOffers a spreadsheet-based interface with live data and Python execution, but lacks Hex's structured data app builder.

Simpler plain-English querying and dashboard generation for databases, but lacks Hex's advanced polyglot notebook environment.
SpecialistSpecializes in embedded white-label customer dashboards, but less suited for internal data team ad hoc analysis than Hex.

Focuses heavily on governed semantic layers and audited SQL generation, but lacks Hex's interactive data app builder.

Stronger automated business reporting and governed chat analysis, but less flexible for custom Python coding than Hex.
SpecialistConverts syllabi into interactive computer science labs and exams, but lacks Coddy's casual bite-sized curriculum.
