Detailed reviews
1. CoHabby
CoHabby starts where SpareRoom stops. SpareRoom shows you who has a room; CoHabby also tells you whether you'd actually want to live with them. You answer 40+ questions about how you live — sleep schedule, cleanliness standards, noise tolerance, guests, cooking, work-from-home habits — and every potential match gets a synergy score based on how your answers line up.
The economics are also different. SpareRoom's free tier lets you browse, but starting new conversations means premium at roughly $10.99 a week to $24.99 a month. On CoHabby, messaging is free for seekers with no caps. The only people who pay are those listing a room, at $2.99 a month.
The honest trade-off: CoHabby is newer and doesn't match SpareRoom's UK dominance or its 17 million registered users. It covers major US metros, and it has no equivalent of speed-flatmating events. If you're searching in London, stay on SpareRoom. If you're searching in the US and care who you end up living with, this is the gap CoHabby was built to fill.
Strengths
- 40+ lifestyle dimensions with synergy scoring
- Free, unlimited messaging for seekers
- In-app chat keeps your contact info private
- Listing a room costs $2.99/mo
- Native iOS and Android apps plus web
Limitations
- Newer platform, smaller user base than SpareRoom
- US metros only — no UK coverage
- No in-person events like speed flatmating
2. Roomies
Roomies is one of the more established US-focused roommate platforms. Listings are structured, you can filter by lifestyle basics, and optional background checks add a screening layer SpareRoom doesn't offer in most US markets. Coverage across American cities is broader than SpareRoom's, which makes it a practical pick outside the big three metros.
The catch is the messaging model. The free tier caps you at around five new contacts, and an active search burns through that in an afternoon. There's also no compatibility scoring — lifestyle filters narrow the pool, but you're still guessing about day-to-day fit. And it's web-only, with no native mobile app.
Strengths
- Broad US coverage
- Lifestyle filters on listings
- Optional background checks
Limitations
- Free tier caps new messages (~5)
- No compatibility scoring
- Web-only, no native apps
3. Diggz
Diggz takes a similar shape to Roomies: US-focused, structured profiles, lifestyle filters, and optional background checks. Its profile prompts go a little deeper on habits and preferences than a plain listing site, which helps you pre-screen before reaching out. It's most active in larger US cities.
Like Roomies, though, the free tier limits you to roughly five new conversations before you need to pay, it's web-only, and the lifestyle data feeds filters rather than any scored match. You can exclude obvious mismatches, but the platform won't tell you which of the remaining fifty profiles you'd actually coexist with.
Strengths
- Detailed lifestyle-oriented profiles
- Optional background checks
- Active in larger US cities
Limitations
- Free messaging capped (~5 contacts)
- Filters, not scored compatibility
- Web-only, no native apps
- Thinner outside major metros
4. Roomi
Roomi's standout feature is government-ID verification — a stronger identity check than most roommate platforms offer, and a real comfort when you're messaging strangers about where you'll sleep. For a while it was one of the most visible roommate apps in the US.
The platform has scaled back in recent years, and listing volume is noticeably lower than it once was. In the handful of large cities where it stays active, the verified profiles are still worth a look. Elsewhere, you may find more empty search results than matches. There's no habit-based compatibility scoring.
Strengths
- Government-ID verification
- In-app messaging
- Still useful in some large cities
Limitations
- Scaled back; lower listing volume
- Coverage inconsistent by city
- No compatibility scoring
5. Craigslist & Facebook groups
For sheer volume, nothing beats the free classifieds. Craigslist's housing section and city-specific Facebook housing groups exist everywhere, cost nothing, and turn over constantly. If you're in a small market where no dedicated platform has traction, they may be your only realistic option.
The trade-off is well documented: no identity verification, no screening, and a persistent scam problem — fake listings, stolen photos, deposit theft. If you go this route, read our guides to Craigslist roommate scams and Facebook Marketplace rental scams first, never pay before seeing a room, and assume nothing about the person behind the post.
Strengths
- Highest raw listing volume
- Completely free
- Available in every market
Limitations
- Well-documented scam problem
- No verification or screening
- No compatibility data of any kind
Why people look for SpareRoom alternatives
SpareRoom is a genuinely good platform — that's worth saying plainly. Staff-screened listings, speed-flatmating events, and the Buddy Up co-search feature are real strengths that most competitors haven't matched. With 17+ million registered users, it's the standard in the UK for a reason. The reasons people go looking elsewhere are specific:
- US coverage is uneven. SpareRoom's American footprint is strongest in New York, Los Angeles, and Chicago. In secondary markets, search results thin out fast, and a platform is only as useful as the listings near you.
- Starting conversations costs money. The free tier lets you browse and reply, but initiating new messages requires premium — roughly $10.99 a week to $24.99 a month. Over a six-week search, that adds up.
- The best listings are paywalled first. "Early bird" access shows fresh listings to paying users before everyone else. In fast markets, free users are often responding to rooms that are already spoken for.
- No habit-based matching. You can filter by budget, area, and move-in date, but SpareRoom won't tell you whether a night-owl smoker with weekly house parties is behind an otherwise appealing ad. Compatibility is left entirely to your judgment from a short bio.
None of these are reasons to write SpareRoom off — especially in the UK or in its strong US metros. They're reasons to run a second platform alongside it, or to switch if you're searching somewhere SpareRoom is thin.
