Crypto all in one
Market intelligence.
One connected world.
Prices, charts, signals and market context — brought together in a deliberately immersive crypto workspace.
Try the sample dashboard below, with no account or installation. It uses fixed example prices. The full app runs locally or in Codespaces with public market feeds.
Built to explore, not just to look at.

Full-size captureThe same workspace, reflowed.
Not tied to a desktop.
Responsive layouts and compact navigation keep the market workspace usable on smaller screens.

Designed on the surface.
Engineered underneath.
Understand the signal.
Rule-based technical analysis combines indicators, volume and available derivatives inputs. It exposes risk levels and source availability; optional AI adds news interpretation.

Handle the real world.
The Worker normalizes public data, caches responses on a five-minute cadence and falls back between providers. Source labels distinguish live, stale and unavailable inputs.

Engineering you can inspect. Tests exercise missing candle coverage, concurrent daily credit claims, wallet isolation and escaped share pages. GitHub Actions runs formatting, lint, type checks, tests and a production build.

A clear boundary
A portfolio project,
not a trading service.
This page combines an interactive dashboard using fixed sample data with real app screenshots. The full runnable app uses example portfolio holdings, anonymous demo credits and browser-local alerts. It has no authenticated accounts, payments or subscription processing.
Technical signals and candle-based outcomes are educational, not executed trades or financial advice. Public providers can be rate-limited; the app makes missing data visible. AI news interpretation is optional and requires your own provider credentials.
