Live · 35 tools watched

For indie devs & small teams paying for 5+ AI tools

Save $480/yr on AI tools — we watch every price change.

When Cursor bumps a plan from $20 → $24, when Claude adds a tier, when Replit deprecates a feature — you find out here, not when your card gets charged at the new rate. The radar logs every published price and feature change across the AI stack so you can switch, downgrade, or cancel before it costs you.

// 02 — How it works

3 steps · zero setup

Snapshot, diff, surface.

  1. 01Step

    Snapshot

    Every 24h the radar opens each tracked tool’s published pricing page and stores the exact plan tiers, currency-amount-period for each price, and the feature list each tier advertises.

    → cursor-ai · pro · $20.00/mo · captured 2026-05-15T03:00Z
  2. 02Step

    Diff

    When a price moves, a tier appears or disappears, or a feature is added or removed, we log the change with a timestamp — verbatim from the vendor, no editorial.

  3. 03Step

    Surface

    You see what moved on the live radar feed, on the public RSS, and (soon) in a Friday email digest — so you can switch, downgrade, or cancel before it auto-bills.

// 04 — What it tracks

Three signals, captured cleanly.

Every day the radar opens each tool’s published pricing page and pulls the same three signals — the plan tiers on offer, the price for each (currency, amount, billing period), and the feature list each tier advertises.

When a price moves, a tier appears or disappears, or a feature is added or removed, the change is logged. The feed below is the running record.

Nothing here is marketing copy — only what the vendor publishes, stored verbatim.

// 08 — How we use this internally

Built on Elofyn Dev API

The radar ships on the primitives we sell.

The social card on every tool page is rendered by the same engine that backs POST /v1/og. We rewrote the six small primitives every developer rewrites once — OG image, PDF, diagram, screenshot, sitemap, OpenAPI mock — and shipped them as the Dev Snippets API. Same auth header, same endpoints any team can call.
