Detailed Reviews
CoHabby
CoHabby is the only housemate-matching app that calculates detailed compatibility scores before you message anyone. You answer 40+ lifestyle questions and the app generates a synergy score for every potential match. As a landlord, you see applicants ranked by how well their living habits match yours. As a seeker, you know before you invest time whether someone's sleep schedule, cleanliness standards, and guest policy align with what you need.
The trade-off is scale. CoHabby is newer than Craigslist or SpareRoom, so the user base is still growing. It currently covers major US metros. But if you're in a covered city and want quality over quantity, it's the best tool available.

SpareRoom
SpareRoom is the go-to roommate platform in the UK and has been expanding into the US. Listings are well-structured, and the speed flatmating events are a genuinely useful feature for meeting potential roommates in person. The UK coverage is excellent; the US coverage is spottier.
No compatibility scoring. You filter by basics like budget and location, then read listing descriptions to gauge fit. Better than Craigslist's free-for-all, but you're still doing most of the screening yourself.
Roommates.com
Roommates.com is one of the oldest roommate platforms, with a large US database. Offers basic preference matching. The significant downside: the free tier barely lets you do anything. You can browse listings but can't view full profiles or send messages without paying. In a world where CoHabby offers full access for free (seekers), paying just to see who posted a room feels like a hard sell.
Craigslist
Still the largest room rental classifieds site in most US markets. Craigslist is free to post, free to browse. The problems are well-known: scam listings, no verification, no compatibility data, and the same interface since 2002. It works as a volume play. You'll get responses. Whether any of them are compatible housemates is entirely left to chance.

Facebook Marketplace
Massive reach thanks to Facebook's user base. Free. Also has a documented fraud problem that the FTC warns about. Stolen listing photos, fake landlord profiles, and deposit scams are common. Messaging someone about a room exposes your full Facebook profile. No compatibility matching. It's reach at the cost of safety.
Apartments.com
Professional-grade platform designed for apartment complexes. High listing quality, excellent search tools. But the pricing is prohibitive for individual landlords: approximately $349 for 30 days. That's fine for a 200-unit apartment building. It's absurd for someone renting a spare room. No roommate matching or compatibility features.
Roomi
Roomi was once a popular roommate app, particularly in New York. It offered background checks and some matching features. However, the platform has significantly scaled back operations and active listings are limited in most markets. If it's active in your area, it may still be worth checking, but don't rely on it as your primary search tool.
Diggz
Diggz offers some compatibility matching features and positions itself as a "Tinder for roommates." The matching is less detailed than CoHabby's 40+ question approach but more than what Craigslist or Facebook offer. Coverage varies by market, and the free tier has limitations. Worth trying alongside other platforms.
How to Choose the Right Roommate App
There's no single best platform for every housemate search. Here's a quick decision framework:
- You want compatible matches: Use CoHabby. It's the only platform with deep lifestyle compatibility scoring.
- You want maximum volume: Use Craigslist and Facebook Marketplace. Be prepared to screen heavily and watch for scams.
- You're in the UK: SpareRoom is the dominant platform there.
- You're a landlord on a budget: CoHabby at $1.99/month gives you compatibility-sorted housemate leads for less than a coffee.
- You want to cast the widest net: Use multiple platforms. CoHabby for quality, Craigslist or Facebook for volume.
