About sub-hunt.com
sub-hunt.com started from a simple, slightly annoying realisation: almost everyone pays for subscriptions they've forgotten about, and the one place that records every one of them — your email inbox — is also the place no tool will search without first asking you to hand over access to it. We thought that trade was backwards, so we built the opposite.
What it does
You export your mailbox to a standard .mbox file and drop it onto the page. sub-hunt reads it and surfaces the subscriptions, recurring charges, one-time payments, invoices, and refunds hiding inside — each with the brand, the amount, the billing cadence, and a link back to the original email. The point is to turn years of buried receipts into one screen you can actually act on.
Privacy is the whole design, not a feature
Every other subscription finder we looked at works by connecting to your Gmail or Outlook account and reading your mail on its servers. sub-hunt has no servers in that loop. Your .mbox is parsed in your browser, inside a Web Worker, using a scanner compiled to WebAssembly. Nothing about your email — not the file, not the senders, not the amounts — is ever uploaded. You don't have to take our word for it: open your browser's Network tab during a scan and watch it stay silent.
How it's built
The mailbox parsing, MIME decoding, and classification are written in Rust and compiled to WebAssembly so they run fast inside the browser tab. Optical character recognition for image receipts runs locally too, from assets served by the same site — no third-party OCR service ever sees your images. The interface is a standard modern web app; the unusual part is simply that the heavy lifting happens on your device instead of ours.
Free, independent, and donation-funded
sub-hunt is free to use and intends to stay that way. It isn't venture-funded, doesn't sell your data (it never has your data to sell), and doesn't charge a subscription to find your subscriptions. Hosting is covered by voluntary donations and, if you accept the cookie banner, a single ad — both entirely optional. Declining the banner loads no analytics and no ads, and the tool works identically either way.
Who it's for
Anyone with an inbox and a nagging sense they're paying for more than they use: people cancelling forgotten streaming services, households auditing shared spend, freelancers and small teams mapping their software costs, or anyone trying to put a name to a mystery charge on a bank statement. If you have email, you have a record — sub-hunt just reads it for you.
