About OumaShu
Last updated:
OumaShu (櫻滿集) is a free directory of 35 online tools that open directly in a web browser. The tools are grouped into 12 “lines”, drawn like a train map, so you can find an image compressor, a screen recorder or a Markdown editor without installing anything or creating an account.

How are tools chosen?
A tool is listed only if it meets all three conditions:
- It is free to use.
- It works in a web browser, with nothing to download or install.
- You can try it without signing up.
29 of the 35 tools are Rollkey’s own projects, most of them on oumashu.top subdomains such as imghub.oumashu.top. The other 6 are established third-party sites; their cards are marked “3rd Party” and they follow their own terms and privacy policies. Each entry is checked when it is added or changed, and the date of that change is recorded.
