A desktop data toolkit built for quant researchers
Download, view, export and serve market data — all from one local app. No SaaS, no recurring fees, your data stays on your machine.
Pull, view, export, serve — end to end
Designed around the quant data lifecycle. Everything happens inside one desktop app.
Local database
DuckDBDownloaded data lands in a local DuckDB file — no cloud, no SaaS. Works offline, easy to back up, and moves with your project. You keep full control of your own data.
Multi-source sync
IncrementalPick the interfaces you need and incrementally sync market, fundamental and macroeconomic data from several providers. Yahoo / FRED / Tushare / Binance behind one unified interface — only new data is fetched, never re-downloaded.
Data view
VisualisationBrowse data without context-switching to Python — charts to spot gaps, tables to spot-check fields. Fix issues before they ruin a backtest.
Data export
Multi-formatSlice and dump the local store — CSV, Excel, ready for your Python/R pipeline or to hand off to a teammate.
AI access (MCP)
MCPA built-in MCP server lets desktop AI assistants query your interfaces, search symbols and pull adjusted bars directly — your data never leaves the machine. Off by default, gated by a local token you control.
Local API
REST APIThe desktop client exposes a local HTTP API. Any language that can issue an HTTP request (Python, Jupyter, R, Node) can query your local data with zero network latency.
Three steps from install to local data
No Docker, no Python environment required. Install, configure, sync.
Install & launch
One-click installer for Windows / macOS. No Docker, no Python.
Configure sources
Enter API keys for the data providers you use (or pick a free one).
Sync & use
Pick the universe you need, sync to local store, then use it in charts / exports / API.
