Open Science Desktop and Synthetic Sciences OpenScience are both open-source AI-for-science workbenches. The names are similar, but the product focus is different enough that researchers can choose by workflow.
- Choose Open Science Desktop if you want a local-first desktop app for macOS, Windows, and Linux, with local files, notebook-style work, artifact provenance, and reproducible run records.
- Choose Synthetic Sciences OpenScience if you want a browser workspace and a
CLI-driven research loop with its
opensciencecommand, TypeScript SDK, agents, and built-in science skills.
| Dimension | Open Science Desktop | Synthetic Sciences OpenScience |
|---|---|---|
| Positioning | Local-first desktop research workbench | Browser workspace / research-agent workflow |
| Primary surface | macOS, Windows, and Linux desktop app | Browser workspace and openscience CLI |
| Technical stack | Tauri 2, React, MCP, OpenCode sidecar, agent skills, local provenance | TypeScript workspace, agents, skills, MCP/plugins, TypeScript SDK |
| Data/workspace model | Local workspace folders, local notebooks, files, previews, provenance, and run records | Browser workspace with file tree, editor, terminal, session history, and scientific renderers |
| Reproducibility focus | Artifact provenance, append-only run logs, SQLite run index, local/remote run records | End-to-end research loop: literature, hypothesis, code, experiments, analysis, write-up |
| Platform fit | Researchers who want a desktop app, local files, private workspaces, and macOS/Windows/Linux support | Researchers who want browser workspace and CLI-first extensibility |

This is a neutral comparison, not an endorsement or criticism of either project. Both projects are independent and open source. The practical difference is product surface: Open Science Desktop emphasizes a desktop, local-first workflow; Synthetic Sciences OpenScience emphasizes a browser workspace and CLI-driven research loop.
