Portals
- RE/MAX
- Sreality.cz
- Bezrealitky.cz
- + more soon
RE/MAX is watched right after you install. Sreality and Bezrealitky you turn on yourself when you set up a profile, after seeing what their terms say about automated reading.
rentczecher is not affiliated with, endorsed by or connected to any of these portals.
A notebook for your home search
The portals are where listings live and where you talk to the seller. rentczecher keeps notes alongside: what is new, what you have already seen and how prices moved. To read an advert, it always sends you back to the portal it came from.
One list
The same flat from several portals shows up once, with a link to each of its postings.
Memory
It remembers what you've seen, what you liked and how the price changed.
Back to the portal
Every listing links to its advert. You read it there and contact the seller there.
Privacy
It runs only on your computer. No account, no cloud.
Free
No subscription and no paid version.
How it works
Everything stays with you.
rentczecher has no server. Your profiles, saved listings and price history live only on your computer. No account, no tracking. And because the code is open, you can check that yourself.
Open source
Built in the open on GitHub.
All of the code is public. Read it, report a bug, suggest a feature or contribute directly. Every star helps more people find the project.
The app is not code-signed yet, so Windows and macOS warn you on first launch. What to do?

What's coming
The plan follows what people need. Missing something? Say so on GitHub.
In progress
- The first release Installers for Windows, macOS and Linux, then a signed Windows installer so it opens without a warning.

Later
- Notifications A notice on your computer when something new turns up, and if you like, an email to your own inbox.
- More portals Each one checked first for what it asks of apps.
- On another computer Run the watching on one machine and connect to it from your other devices.
Devlog
How rentczecher gets made: what worked, what didn't and what I learned along the way.
Is it legal to release this? Before going further I checked whether publishing rentczecher is safe. The answer shaped the tool: local, free, linking back to the portals, and licensed GPL. Read → A welcome and a choice of language The app learned light and dark, Czech and English, and a welcome wizard that asks for both on the first launch. Read → Each flat once The same flat on two portals used to be two rows in the inbox. Now it is one, and what you have seen follows the flat, not the posting. Read →
Questions
Is it really free?
Yes. No subscription, no ads, no paid tier.
Which portals does it watch?
RE/MAX, Bezrealitky and Sreality. RE/MAX is on from the start. Sreality and Bezrealitky are off by default, and you turn them on yourself in a profile after seeing what the portal asks. More portals will follow, each one checked first for what it asks of apps. rentczecher is not affiliated with, endorsed by or connected to any of these portals.
Does it watch while my computer is off?
No. It checks the portals when you press Run scan, with your computer on and the app open. Scans in the background are on the way. Whatever appeared in the meantime shows up on your next scan.
Is the code really open?
Yes, all of it is on GitHub under the GPL-3.0 licence. Report bugs and ideas via Issues.
Why do Windows and macOS warn me?
The app is not code-signed yet. On Windows, choose More info, then Run anyway. A signed Windows installer is on the way. On macOS, signing requires Apple's developer program, which costs €99 a year. I don't earn anything from the app, so I have no reason to spend that. You can still run the app, it just takes a little more work. Open System Settings → Privacy & Security and choose Open Anyway next to rentczecher.
