Local databaseDuckDB

All your data in a local DuckDB file you own

Downloaded 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.

  • Single-file DuckDB — columnar storage, fast queries
  • Everything stays on your machine, works offline
  • Back up, copy or move it with your project
  • No subscription, no cloud lock-in — the data is yours

Multi-source syncIncremental

Incrementally sync from multiple providers into local storage

Pick 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.

  • Pick by interface, ticker universe or date range
  • Incremental sync — only fetches what's new
  • Unified interface across providers, schemas normalized
  • Background tasks that don't interrupt your research

Data viewVisualisation

Validate completeness and correctness in-app

Browse data without context-switching to Python — charts to spot gaps, tables to spot-check fields. Fix issues before they ruin a backtest.

  • Price / candlestick chart view
  • Paginated tabular browsing
  • Jump-to-date and ticker search
  • More detail as we publish per-feature docs

Data exportMulti-format

Export to whatever format your scripts use

Slice and dump the local store — CSV, Excel, ready for your Python/R pipeline or to hand off to a teammate.

  • CSV and Excel for analyst hand-off
  • Filter-driven subset exports
  • Saveable export jobs that re-run on a schedule
  • Or take the whole DuckDB file into your pipeline

AI access (MCP)MCP

Plug your local data into Claude, Cursor and other AI apps via MCP

A 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.

  • One-click enable, copy-paste config for Cursor / Claude Desktop / Cline
  • Honest adjustment metadata — the AI is told whether bars are adjusted
  • Local-only and token-gated — off by default, you control access
  • No extra install — the stdio bridge reuses the app runtime

Local APIREST API

Built-in HTTP server, called directly from your scripts

The 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.

  • localhost HTTP — no network round-trip
  • Language-agnostic — anything that can fetch works
  • JSON responses with stable schemas
  • More detail as we publish per-feature docs
