NYC rental alert tools compared: StreetEasy, FirstMover, LeaseSwap and others
Every apartment alert tool is defined by the sources it reads. Most of them read the same ones. Here is what each covers, what it charges, and where it is blind.
We make one of the tools described below, so read this with that in mind. We have tried to be accurate about what everyone else does well, including where they beat us.
The only question that matters
Every alert tool is a pipe with a source at one end. The interface, the pricing and the notification channel are all secondary to a single question: what does it read? Two tools reading StreetEasy will show you the same apartments a few seconds apart. A tool reading something else entirely is not a competitor to them; it is a different product.
StreetEasy's own saved searches
Free, and the correct starting point. Reads the brokered market comprehensively, with price history and days-on-market attached — data nothing else here has.
The limit is delivery. Alerts are batched rather than instant, typically as a digest. On a brokered one-bedroom that is fine. On anything that clears in an hour it is not, which is the entire reason the rest of this list exists. We have written about StreetEasy at more length.
FirstMover
Watches StreetEasy and notifies you the moment a listing goes live, ahead of StreetEasy's own alerts. It charges a one-time price rather than a subscription, which is unusual in this category and worth checking on their site if StreetEasy is your market.
They also publish an open data project on the NYC rental market, which is more public contribution than anyone else in this category makes. If your search is whole apartments on standard leases, this is probably the most efficient thing on this page.
LeaseSwap
Aggregates several sources — StreetEasy, LeaseBreak, NYBits, Reddit, and on the paid tier RentHop and Craigslist — with email alerts on matching listings. A free tier exists.
Broader coverage than a single-source tool, and the inclusion of LeaseBreak and Reddit means it catches some lease-transfer inventory the pure listing-site tools miss. Email delivery rather than SMS.
RentReboot
The most feature-complete of the group: alerts across a large number of sources, including rent-stabilised buildings and Housing Connect lotteries, with text alerts on the paid tiers. Subscription pricing, broadly in the $12–20 a month range depending on plan.
The rent-stabilised and housing-lottery coverage is genuinely distinctive and nothing else here replicates it. If that is what you are looking for, this is the tool.
RentHop, PageCrawl and general page monitors
RentHop has its own alerts over its own inventory. Generic page-change monitors like PageCrawl will watch any URL and ping you when it changes, which works on a management company's vacancy page that has no alerts of its own. Fiddly to set up, but the only option for sources nobody else covers.
HomeMatch
We read one source and it is not a listing site: NYC Facebook rental and roommate groups. Rooms, sublets, lease transfers, small owner-landlords — the inventory nobody pays to advertise, which is therefore invisible to every other tool on this page.
Because group posts have no fields, we parse each one into rent, layout, neighborhood and move-in date, and we say plainly which of those the post never stated. You get one text per match, minutes after it posts, capped at a daily limit you set. Your first 10 are free, then 2¢ per match delivered, with no subscription.
Our gaps, stated directly: we do not see StreetEasy, Zillow, Craigslist or Housing Connect. We have no price history and no days-on-market. We do not verify that a poster controls the apartment they are advertising — that checking is yours to do. And we cover New York City only.
Choosing
- Whole apartment, standard lease, StreetEasy market: FirstMover, or StreetEasy's own alerts if you can live with a digest.
- Rent-stabilised or a housing lottery: RentReboot, which is the only one covering these.
- Widest listing-site coverage in one place: LeaseSwap.
- A room, a sublet, a short lease, or a budget the brokered market does not serve: HomeMatch, because that inventory is not on the listing sites at all.
Most people searching seriously end up running two: one covering the brokered market and one covering the informal one. They are different halves of the city and no single tool reads both.
What to actually compare
Beyond the source, four things differentiate these tools in practice, and pricing is the least important of them.
Latency. Instant, or a digest? On a brokered one-bedroom a digest is fine. On a room it is useless. Ask what the actual delay is, not whether alerts are “real-time”, which everyone claims.
Channel. Email is easy to ignore and easy to batch. SMS and push get looked at within minutes, which is the entire point when the window is an hour.
Filtering. A tool that cannot filter to your budget and neighborhoods sends you noise, and a channel you learn to ignore is worse than no channel.
Volume control. Any instant alert on a busy source needs a cap, or you stop reading it by the third day.
Two questions worth asking any of us
What sources do you read, exactly? Not “30+ sources” — which ones. Tools reading the same listing sites are substitutes for each other; a tool reading something else is not.
What do you do when a listing is missing information? The honest answer is that plenty of listings do not state the lease term or the deposit. A tool that silently fills gaps is worse than one that tells you the gap exists.
What none of these solve
An alert gets you to the listing first. It does not write your message, verify the poster, or make you able to view tomorrow. In a market where response time decides most outcomes, the alert is necessary and nowhere near sufficient.
It also does not check whether the listing is real. Every tool here, ours included, passes along what a source published. That verification remains yours, and on the informal sources it matters considerably more than on the brokered ones.
We watch NYC Facebook rental groups and text you the rooms and apartments in your range. within 30 minutes of the post going up, not the next morning. Your first 10 are free.
