Suprascribe is an open-source subscription tracker that finds recurring charges by scanning your email inbox, then gives you one dashboard to audit, group, and cancel them. Its pitch is direct: subscriptions silently multiply, so discovery should be automatic and the upgrade to PRO should be a one-time payment, not another subscription.[1][2]
Quick verdict
Open-source inbox-driven subscription tracker with a one-time PRO upgrade. Suprascribe is an AGPL-3.0 licensed subscription tracker that automatically discovers recurring charges from Gmail, Outlook, iCloud, or any IMAP inbox and manages them from a dashboard with spend views, history, and renewal reminders. A free tier covers manual tracking while a one-time PRO payment unlocks auto-discovery, and the Next.js plus Supabase codebase can be self-hosted with documented setup.[1][2][3]
What Suprascribe does
Suprascribe connects to Gmail, Outlook, iCloud, or any IMAP provider and scans for subscription payments, renewals, and cancellations. The README documents a two-model pipeline over OpenRouter: one model screens fetched emails for subscription content and a second extracts subscription details, with an option to bring your own AI key instead.[1][2]
Subscriptions land in a dashboard with active and past states, monthly and annual spend views, upcoming renewals, grouping and search, a calendar view, and renewal email reminders sent a configurable number of days ahead. Quick unsubscribe links jump to each service's cancellation page.[1][2]
The free Basic tier covers the dashboard with insights, unlimited manual subscription creation, multi-currency support, and bring-your-own AI key discovery. The PRO upgrade, sold once via Stripe, unlocks auto-discovery, complete subscription history, search/sort/grouping, quick unsubscribe, renewal reminders, calendar view, and email support.[1]
Who it fits
Suprascribe fits individuals who suspect they pay for forgotten subscriptions and want inbox-driven proof before cancelling. Per-user OAuth connections, per-user row-level security, and renewal reminders all point at personal use rather than team administration.[1][2]
It fits self-hosters comfortable creating a Supabase project, running SQL migrations, and registering OAuth clients, who want subscription data in a database they control under an AGPL-3.0 codebase.[1]
Limits to weigh
Auto-discovery depends on third-party AI models over OpenRouter by default, or on a user-supplied key. No offline capability is documented, and the app requires its Supabase backend, so an internet-connected deployment is assumed.[1]
The managed service's data locations are undisclosed on the observed pages, and no enterprise SSO or SLA is documented: sign-in is consumer OAuth via Google, Microsoft, or Apple, and support is the PRO email channel. Buyers with residency or SSO requirements should treat these as open questions.[1][2]
Suprascribe tracks subscriptions only; it is not a general finance manager. People wanting budgets, bank accounts, and double-entry accounting alongside subscriptions should compare it with a broader tool such as Firefly III rather than expecting Suprascribe to cover all finances.[1][2]
Questions worth asking
Is Suprascribe free, and what does PRO cost?
Suprascribe has a free Basic tier with a subscription dashboard, unlimited manual entries, multi-currency support, and bring-your-own AI key discovery. The PRO upgrade, which adds inbox auto-discovery, full history, renewal reminders, calendar view, and quick unsubscribe, is sold as a one-time Stripe payment rather than another subscription.[1]
Can I self-host Suprascribe?
Yes. The repository documents running Suprascribe against your own Supabase project: clone the repo, install with Yarn, run the SQL migrations, register Google or Microsoft OAuth clients for email discovery, configure environment secrets, and start with yarn dev or build for production. No Docker image is documented.[1]
