Charts for the numbers you'll be held accountable for.

Five reasons Sextant beats roll-your-own.

*A product is one application you ship, with all of its environments and releases — dev, staging, and production together count as one. An internal tool counts as one. Launch rates · subject to change as the catalog grows. Indie is a single charge that does not renew and installs updates for 12 months. The annual tiers renew automatically at the price shown every 12 months until you cancel; cancel anytime using the link on your receipt, effective at the end of the paid period. Either way, widgets already in your repo stay yours to use and ship — see the license. Every purchase is covered by our 14-day money-back guarantee. All prices in USD.

Questions, answered.

What is Sextant?

Sextant is a paid shadcn/ui component registry of intelligent chart widgets for React across product, growth, finance and ops — conversion funnels, retention curves, revenue and NRR waterfalls, cash runway, forecasting, and anomaly detection. Every widget ships with built-in loading, empty, error and stale states and a one-sentence narrative that explains the chart automatically. Install any widget with `npx shadcn add @sextant/<widget>`.

How do I add a cash runway chart to a React or Next.js app?

Run `npx shadcn add @sextant/fpa-cash-runway`. The CLI copies a typed React/Recharts component into your project that renders monthly cash balance, a projected depletion line, a runway-in-months figure, and an auto-generated narrative. Pass your own data through the typed prop — no chart wiring required.

How is Sextant different from Tremor or raw shadcn charts?

Tremor and the built-in shadcn chart primitives give you generic chart shapes — you still build the domain logic, the loading/empty/error states, and the explanation yourself. Sextant ships domain-specific widgets across product, growth, finance and ops with the math, production states, and a deterministic narrative already baked in, so a retention curve or cash-runway card is one install instead of a day of work.

Do Sextant charts need an LLM or API key to generate insights?

No. Every narrative — anomaly callouts, forecast bands, variance drivers, cohort highlights — is computed by pure, deterministic TypeScript (z-scores, Holt linear forecasting, waterfall bridges). There is no LLM, no API key, no network call, and no hallucination risk — which is what teams shipping production dashboards need.

Which stack does Sextant work with?

Sextant targets React 19, Next.js, Tailwind CSS v4, Recharts 3, and shadcn/ui. Widgets install through the standard shadcn CLI, resolve their dependencies automatically, and inherit your existing shadcn theme tokens — plus a chart-first theme builder for tuning the chart palette.

Can AI coding agents like Cursor or Claude Code install Sextant widgets?

Yes. Sextant ships an MCP server so AI agents can search the catalog, inspect a widget's data contract, bind your data, and emit a ready-to-paste `npx shadcn add @sextant/<widget>` command. The widgets are also fully documented for agents that read `/llms.txt`.

Why a subscription if the code installs into my repo?

You're not paying for the code — you own that after one install. You're paying for it to stay correct: new widgets, refinements, and fixes as React and Next change underneath you. Cancel anytime and you keep every widget you've already installed, frozen at its current version; the subscription only gates pulling new and updated ones. Solo devs and single products can instead buy the Indie tier once — no subscription, and it installs updates and new widgets for 12 months, after which the widgets in your repo stay yours and are frozen the same way.
