Built for anyone who needs
to find things on Reddit

Set it up once. Let it run in the background. Get notified the moment a matching post appears.

Freelancers hunting clients

Monitor r/forhire, r/entrepreneur for "need a developer" or "looking for designer" posts the moment they go live.

Apartment hunting

Track r/NYCapartments, r/londonhousing for listings that match your criteria before anyone else sees them.

Hardware deals

Watch r/hardwareswap and r/buildapcsales for the specific GPU or component you're after.

Brand & competitor monitoring

Track mentions of your product, brand, or competitors across relevant communities in real time.

Recruiting

Find talent on r/cscareerquestions, r/forhire — catch "open to work" posts early.

Sales lead generation

Spot "looking for" or "recommendations needed" posts in your niche and reach out at the right moment.

Everything you need,
nothing you don't

Lightweight, private, and dead simple to set up.

Desktop notifications

Get a macOS notification (with sound) the instant a new matching post appears.

No API key needed

Uses Reddit's public JSON endpoint. No accounts, no tokens, no rate-limit headaches.

Multiple monitors

Run separate monitors for different use cases — each with their own subreddits and keywords.

Exact phrase matching

Match full phrases, not loose keywords. "looking for a dev" won't fire on posts about "dev tools".

Configurable intervals

Check every 5, 10, 30, or 60 minutes. Set freshness from 1 hour to 7 days.

Fully local & private

Everything runs on your Mac. No cloud, no sync, no data sent anywhere.

Dark & light mode

Matches your workflow. Toggle anytime from the app toolbar.

No duplicate alerts

Seen post IDs are cached — you'll only ever be notified about new posts.
