MegaRepl is a fast, extensible, multi-language REPL designed to turn ideas into running code in seconds. Whether you’re sketching a quick script, exploring a dataset, testing an API, or teaching a concept live, MegaRepl gives you an interactive, responsive environment that keeps you in flow.
Built for flexibility, it supports multiple runtimes through a plugin system and pairs a smart editor with rich output so you can iterate quickly without leaving your console. Sessions are easy to save, share, and reproduce, making MegaRepl as useful for demos and workshops as it is for day‑to‑day development.
Key features:

- Smart editing: Inline completions, syntax highlighting, quick docs, and signature help.
- Introspection and debugging: Inspect variables, browse objects, and step through snippets without breaking your session.
- Rich outputs: Render tables, plots, and HTML; export transcripts to Markdown or HTML for documentation and sharing.
- Reproducible sessions: Snapshot dependencies and environment settings per project to ensure consistent results.
- Integrations: Connect with Git, containers, and language servers; pipe commands to and from your existing tools.
- Collaboration: Share live sessions for pair programming or teaching with granular permissions.
- Customization: Themeable UI, configurable prompts, and a straightforward plugin API to tailor the experience.
