Bytky: find your next flat or house to rent or buy, anywhere in the Czech RepublicFind your nextflat.

Yes. Reading never needs an account: the map, every listing and area page, the paste box and the extension are free. A free account adds two saved searches with alerts, a commute place, the flat-hunt board and extension sync. Bytky Plus, for heavier searches, is coming and isn't on sale yet.

From public property listings across the Czech Republic, which Bytky checks around the clock, recording a new version whenever the price, the charges, the status or the listing itself changes. Timetables come from PID open data, places from OpenStreetMap and the national school and healthcare registers, and addresses and boundaries from the state register (RÚIAN).

From comparable listings: the same kind of property, a size within 25 % and a similar layout, live or listed in the last 90 days. Bytky looks within 500 m first and widens to 1 km, 2 km and then the district until it has enough, then takes their weighted typical price per m², with the middle half of them as the typical range. Where the listing sits in that spread gives the verdict, from Good deal to Pricey, and fewer than 8 comparables means no verdict. These are asking prices, not sale prices: Bytky has no transaction data.

Bytky runs OpenTripPlanner on the PID timetables. For each place you save, it works out how long the trip takes by public transport to arrive at the time you choose, door to door, including the walk to and from the stops. Times are computed for small hexagonal cells a few hundred metres across, so listings in the same cell share a time. They cover Prague and Central Bohemia, by public transport only.

How far you can get in 10, 20 and 30 minutes from a listing, or from any point you right-click (or long-press) on the map, drawn as three bands. Choose public transport (all of it, metro only, or metro and tram), walking or cycling, and when you leave: weekday 8:00 or 17:30, weekday 22:30 or Saturday 10:00. Each band counts the places inside it: groceries, food and drink, schools, kindergartens, health, parks, playgrounds, sport and services.

Listings, price history, fair prices and nearby places cover the whole of Czechia. Transit scores, live departures, commute times and the reach map cover the PID area: Prague and Central Bohemia. Every region, district, town and municipal part has an area page, and so do 231 neighbourhoods in eight cities, Prague and Brno among them.

New listings on both sites usually reach Bytky within a quarter of an hour, and both sites are swept in full every few hours, which catches price changes, reservations and removals. Fair prices are rescored when a price changes and refreshed every night; market statistics and area pages update daily.

Each listing is placed from the source GPS or the state address register (RÚIAN) and graded by how exact it is: exact address, street, area or municipality. Commute times, reach and nearby places are measured from that point, so they are only as exact as the location.

No. Everything is on the website: the map, every listing and area page, and the paste box for a link someone sent you. The extension brings the same report to the listing sites themselves, in a panel beside every listing and as badges on search results. It's free and needs no account.

Yes. Bytky runs an MCP server that Claude, ChatGPT, Cursor and other assistants connect to with your Bytky account. Ask in plain language and the assistant can search listings, read a listing's history and fair price, look up an area's market and work out reach, with the same data as the site. The AI assistants page has the steps for each app.
