StreetFerret Review: Is It Worth $4 a Month in 2026?

StreetFerret calls itself "the every-street game for runners and cyclists", and that sentence is doing more work than it looks. Almost everything people get wrong about this tool, in both directions, comes from skipping past it.

This is a review of what it actually is, who it is genuinely good for, and the one requirement that decides whether you can use it at all.

One disclosure before any of it: we make Fogbreaker, which clears fog off a map as you walk, so we compete with StreetFerret in the broad sense. We think StreetFerret is a good tool and this review says so. We also think a lot of people arrive at it wanting something it was never built to do, which is the more useful half of the article.

What StreetFerret actually is

Checked on 9 September 2026, because all of this moves.

It is a website, not an app. There is no iPhone or Android version, and no App Store or Google Play link anywhere on the site. You use it in a browser, including the live tracking feature.

It does not record anything. StreetFerret reads your Strava history. You connect Strava once, your activities sync automatically, and StreetFerret checks those GPS traces against OpenStreetMap to work out which streets you have covered, city by city. No Strava account, no map. There is no other way in: no Garmin, no manual upload, no built-in tracker.

What you get on top of that:

• Completion Map. Street-by-street coverage per city, showing what is done and what is still open.
• Live Ferret. Your route in real time, so you can pick up streets you missed before you head home. This is the standout feature and the one with no obvious equivalent elsewhere.
• Leaderboards, both local and global, so your city progress sits against other athletes'.
• Activity Calendar and a per-city calendar, for training history and consistency.
• Data export as CSV or GeoJSON, which is rarer than it should be and worth real credit.

The site also says plainly: "No ads. Never sold." For a service reading your full location history, that is the right posture, and it is stated rather than buried.

The requirement that decides it

Are you already a Strava person?

If yes, StreetFerret is close to free money. Your existing history gets read on connection, so the map is populated the moment you sign up, and nothing changes about how you record.

If no, understand what you are agreeing to. Using StreetFerret means signing up for a fitness social network, remembering to hit record before every run, ride or walk, and accepting a second company in the chain between your feet and your map. That is not a dealbreaker for a runner who was going to open Strava anyway. It is a genuine obstacle for someone who just wanted to see their neighbourhood fill in.

The second half of the sentence matters too: runners and cyclists. Strava does record walks, and walked streets do count, so nothing blocks a walker technically. But the framing, the leaderboards and the training calendar are all built around athletes with a training habit, and a walker will feel it.

Free versus Pro

The free tier is unusually generous. Live Ferret, the leaderboards, the calendars and the data export are all there, and the tier includes a 30-day trial of the rest. The wall is the 10 city map limit, which most people will never touch. Ten cities is a lot unless you travel constantly or live somewhere carved into many small municipalities.

At $4 a month Pro is inexpensive, and more to the point the free tier is a usable product rather than a demo. How StreetFerret lines up on price and features against CityStrides, Wandrer and Squadrats is a longer comparison, and we did that one separately in apps like CityStrides.

The honest downsides

• The browser dependency. Live Ferret is the best idea here and it lives in a mobile browser, which is a worse place for a real-time tracking screen than a native app. Screen wake, backgrounding and battery all behave less predictably.
• Strava is a hard requirement, not a convenience. If Strava changes its API terms, every tool in this category is affected at once.
• The community is smaller than CityStrides'. The leaderboards and local rivalries that make this genre addictive are thinner, which matters more than it sounds when the whole point is competitive completion.
• It is aimed at athletes. If you are not training, you are using a training tool sideways.

Use it if

• You already use Strava and you want your existing history turned into a completion map today.
• You run or cycle with a training habit and want a clearer goal than distance.
• You want live route feedback mid-activity, which nothing else in this category really does.
• You care about getting your own data back out. The CSV and GeoJSON export is a genuine reason to prefer it.

Do not use it if

• You do not use Strava and do not want to. There is no path in. Nothing else on this list matters if this one applies.
• You want an app on your phone. There isn't one, and there is no sign of one coming.
• You want walking to be the point rather than a recorded activity type.
• You want a map that fills in without you remembering to press record.

Those last two are the group we built for, so here is the disclosure in full, including the part that does not flatter us.

Fogbreaker does not do street completion. We do not tick named streets off a list, and we never will in the way StreetFerret does. Our number is area coverage: real land area uncovered divided by the area's total size, across five levels from country down to neighbourhood, with boundaries from Overture Maps. If what you want is a named street marked complete, StreetFerret is genuinely the better tool and we are not going to pretend otherwise. We wrote up the difference between the two ways of counting in what percentage of your city you have walked.

What we do differently is the recording. Fogbreaker is a phone app on iOS and Android that records for itself, so there is no Strava account, no browser tab and nothing to press before you leave. Your city starts hidden, walking clears it, and the fog is tuned so a walk around your neighbourhood is a visible event. On top sit XP, levels, daily quests, streaks and a friend leaderboard. It is free, with an optional Pro subscription that is never required, and it speaks eight languages.

The honest limits on our side: the free tier only clears fog at walking speed, so a bike ride will not fill your map the way StreetFerret's will, and lifting that is a Pro feature. The app needs an internet connection to track. And we are far newer and far smaller than anything else named here. On data: we are Teratis Solutions GmbH, a German company, your data sits on EU servers under GDPR, we do not sell it or share it for advertising, and you can delete your account and everything in it yourself.

If you want the concept explained rather than shopped, that is fog of war for real life.

The verdict

StreetFerret is the best-value tool in the every-street category, and the requirement it puts on you is the whole review.

If you have a Strava habit, install nothing, connect it, and see your map populate from years of history for free. Ten cities will cover most people indefinitely, and $4 a month is a fair price for unlimited if it does not. Live Ferret alone justifies a look, and the data export earns trust that most of this category has not.

If you do not have a Strava habit, the honest answer is that StreetFerret is not the tool you are looking for, and no amount of liking the idea changes that. The question then becomes whether you want street completion badly enough to build a Strava habit for it, or whether what you actually wanted was to watch your own neighbourhood fill in as you walk. Those are different products, and it is worth knowing which one you came for.

If it is the first, we lined up the whole category, including how StreetFerret compares with CityStrides, Wandrer and Squadrats, in apps like CityStrides. If it is the second, start with how to walk every street in your city.
