The open-source data layer for robotics and physical AI
Log, store, and view images, point clouds, 3D transforms, and time series together in one viewer.
Record multi-rate, multimodal data as column-chunks in rrd files, or convert from other formats.
Run full dataframe or SQL queries over robotics data, down into columns, time ranges, and values.
Add derived columns and evolve schemas without breaking history, on the edge or near the data.

Agent Skills that give your coding agent real design taste
Every Skill is designed, written and tested by the Skillry team, with templates and scripts built from a finished piece of work.
Skills cover web pages, slide decks, images, video and reports, so your agent can produce a range of assets.
Install and run Skills inside Claude Code, Codex, Cursor, GitHub Copilot, Gemini CLI and more.
Each Skill page shows a real result it generated, so you can judge the visual style before adding it.
