# What Is LuxAlgo? (/platform/getting-started/what-is-luxalgo)



LuxAlgo is a trading technology company. We built Vela, our next-generation charting platform: state-of-the-art charts for every market, with Quant, our coding agent, built in, and the largest indicator library in trading. LuxAlgo was founded in 2020 and is headquartered in Boston. It's free to start at [luxalgo.com](https://www.luxalgo.com).

* **[Vela](/platform/charts/introduction)** runs in the browser at [vela.luxalgo.com](https://vela.luxalgo.com/chart). Its charts are engineered in-house and cover crypto, US stocks and ETFs, forex, and commodities on every plan, including Free, plus live CME futures on every paid plan.
* **[Quant](/platform/quant/introduction)** is our coding agent and the intelligence inside LuxAlgo, built into Vela. It reads your chart, writes and repairs indicator and strategy code, proves it against history, and runs what you approve. Ask in your own words; no code required.
* **[The Library](https://www.luxalgo.com/library/)** is the largest indicator library in trading, with 800+ indicators. Free indicators come with every plan, and the full Library with every paid plan.
* **[Orderflow](/platform/charts/order-flow/introduction)** is built from real trades on every plan, including Free: footprint and TPO charts, volume profiles, delta, and more. What scales with your plan is Orderflow lookback, from 1 day on Free to full history on AI Ultra.
* **[Plans](/platform/account/plans)**: Free, Essential, Premium, Ultimate, and AI Ultra. Monthly credits, Orderflow lookback, strategy alerts, and chart history grow with each tier.
* **Open source**: we started in the open and have published free, open-source indicators since 2020. [PineTS](/developers/pinets), our open-source Pine Script® runtime, is how Pine Script® runs on LuxAlgo. The open-source core of Vela by LuxAlgo, the charting library behind Vela, lives at [velacharts.dev](https://velacharts.dev), with its [developer docs](/vela) on this site.

## How it fits together [#how-it-fits-together]

The platform is layered: in Vela, a **workspace** is your saved setup, **charts** live inside it, and **Quant** operates on whichever chart is active.

1. **[Workspaces](/platform/workspaces)**: your saved setup. It holds charts, layout, drawings, indicators, and [panels](/platform/workspaces/panels) like the [watchlist](/platform/workspaces/watchlist). Everything autosaves, and a workspace can be shared as a copy. The [Journal](/platform/workspaces/journal) sits beside that setup and keeps trades on your account.
2. **[Charts](/platform/charts/introduction)**: symbols, timeframes, multi-chart layouts, [drawings](/platform/charts/drawings), [indicators](/platform/charts/indicators), and native [order flow](/platform/charts/order-flow/introduction) (footprint and TPO chart types, volume profiles, and delta tools).
3. **[Data](/platform/charts/data)**: LuxAlgo market data. Crypto, US equities, forex, and commodities on every plan, including Free; live CME futures on every paid plan. Candles everywhere, plus order-flow footprints on crypto, US equities, and CME futures. No exchange accounts or API keys needed.
4. **[Quant](/platform/quant/introduction)**: our coding agent. It writes and repairs [indicator](/platform/quant/indicators) and [strategy](/platform/quant/strategies) code for the active chart, working from a written request or a screenshot, and backtests strategies against the chart's history. It also sets up the chart and [marks it up](/platform/quant/drawing) at prices read from the chart's own bars. The code is real Pine Script® you can inspect and edit, and it runs on LuxAlgo through PineTS, our open-source runtime.

## Strategy Screener [#strategy-screener]

[Strategy Screener](/platform/ai-backtesting/introduction), previously called the AI Backtesting Assistant, sits beside Quant on LuxAlgo. Use it to find strategies built from LuxAlgo toolkit conditions and inspect their backtests. It shares Quant's credit balance.

[Strategy Alerts](/platform/ai-strategy-alerts/introduction) send live notifications for Strategy Screener strategies. Alert allowances depend on your plan; webhook automation is included with Premium, Ultimate, and AI Ultra.
