| Atlas UI | Kanban boards, an Object Pascal syntax editor and verified update staging | Atlas VCL |
| Atlas Info | Data-aware grid, lookup, filter and rich text controls | Atlas VCL |
| Atlas Plot | General-purpose charts and image export | Nothing |
| Atlas Plot Pro | Statistics, box plots, heat maps, radar plots and analysis series | Atlas Plot |
| Atlas Fin | Financial charts with indicators and multiple panes | Atlas Plot |
| Atlas Virtual Grid | A fast custom-drawn grid over memory, on-demand or chart data | Atlas Plot |
| Atlas Log | Structured, thread-safe logging with sinks and a live viewer | Nothing |
| Atlas Crypto | Hashing, key derivation, encryption and signatures over Windows CNG | Nothing |
| Atlas MQTT | An MQTT 3.1.1 client and a small embeddable broker | Nothing |
The pages describe the code as it is today. Each guide says what is not implemented yet. The Atlas APIs are original: they are not source-compatible with other component libraries, and forms from other libraries do not load into them. See the FAQ for platform scope and licensing questions.
