Zero G
A competent technical user can build a useful self-hosted replacement using existing open-source trading/backtest projects and libraries; Zero-G's pages provide no evidence of durable moats or unique data.

Open-source builds that already do this
Every project below is open source and already does this job today. Fork one, self-host it, or take the parts you need - the build prompt further down assumes an empty file, and this is the shortcut past that. Licences differ; check the one on each card before you ship. All Zero G alternatives, with the arithmetic →
What a replacement has to do
- Ingest market data, visualize a market-map, backtest strategies, and send orders to an exchange/broker.
What it still won’t have
- polished commercial UI/UX and product polish
- SLAs and uptime guarantees for live order routing
- customer support and onboarding
- any proprietary models, datasets, or integrations Zero-G may bundle
- regulatory/compliance assurances or insurance
What remains hard
- Product polish and ongoing maintenance

Runnable build prompt
Build a minimal self-hosted trading map web app using Python FastAPI, Postgres, Celery, and React + D3 for the frontend. Core features in scope: 1) ingest live market data (exchange REST/websocket) and store normalized ticks/ohlc in Postgres; 2) simple backtester that replays historical OHLC from Postgres and outputs PnL metrics; 3) broker integration using CCXT for live order placement, cancels, and position sync; 4) interactive market-map UI showing symbols, metrics, and allowing strategy parameter edits and paper/live toggles; 5) simple auth, logging, and audit of orders. Out of scope: mobile app, institutional compliance/custody, advanced risk engine, high-frequency low-latency execution. Require: error handling for all external calls, unit and integration tests for ingestion, backtest, and order flows, Docker-based deployment manifests, and basic CI pipeline.
How we checked
How the score was reached
- Partly verdict base52
- An open-source build was found+5
- 3 cited sources+3
- Evidence score60
The base comes from the verdict. Everything under it is a check that either happened or did not, and each one is a fact frozen in this record rather than a judgement made at render time - so the same evidence always produces the same number.
