7 Best Catbox.moe Alternatives in 2026: File Hosts Compared

#1

0x0.st

Best for: Developer curl uploads

Visit 0x0.st

0x0.st, known as The Null Pointer, is a temporary file hoster run as a small-scale project with a distinctive plain-text homepage. Uploads work through HTTP POST with curl, for example curl -F'file=@yourfile.png' https://0x0.st, and the service calculates retention from file size: small files last up to a year, larger files closer to the 30-day minimum.

For developers and terminal users who share logs, screenshots and builds, 0x0.st is the closest in spirit to Catbox's simple hosting, though its lack of a browser upload form rules it out for non-technical users. Respect its terms: the operator moderates uploads and blocks IPs for violations, and the site asks client software authors to use identifying user agents, avoid masquerading as browsers, and get user consent before uploading logs. Its management tokens also let you delete a file immediately or shorten its expiry, which is useful when a share was sent to the wrong person.

#2

file.io

Best for: Private one-time shares

Visit file.io

file.io calls itself super simple file sharing, and its model is like Snapchat for files: upload a file, share the link, and after it is downloaded the file is completely deleted. For added security you can set an expiration so the file deletes within a set time even if never downloaded, and all files are encrypted in storage with HTTPS and TLS for transfer.

With uploads up to 4 GB, a REST API and no account required, file.io is the best Catbox alternative for private one-time shares. Just remember the trade-off: if the recipient misses the download, you upload again. Its API also supports direct text sharing and custom expiry values in days, weeks, months or years, so developers can build one-time secret sharing into scripts and tools without storing anything themselves.

#3

Gofile

Best for: Larger free shares

Visit gofile.io

Gofile provides reliable, secure cloud storage with a simple pitch: free for quick shares, with fair and predictable pricing when you need permanence or scale. Uploads from the homepage need no registration, the share link is ready before the upload even finishes, and the file manager adds content imports, recycle bin management, granular permissions, search, tags and descriptions.

With over a decade of operation claimed with zero data loss and no security incidents, Gofile is the best free Catbox alternative for larger files and ongoing sharing. Teams that need permanent storage should look at its premium tier rather than relying on temporary free shares. Its file manager also supports multiple accounts with instant switching, so uploads keep running no matter which account is active, and its privacy-by-design approach uses no tracking and no third-party tools, with every component designed, built and operated in-house.

#4

Uguu

Best for: Tiny quick shares

Visit uguu.se

Uguu is temporary file hosting with a one-line promise: maximum upload size 128 MB and files expire after 3 hours. That short window makes it ideal for sharing a screenshot, a config file or a small build with someone who is online right now, and useless for anything that needs to last the week.

For Catbox users who share small files in chat and want them gone fast, Uguu is the simplest option here by far. For anything larger or longer-lived, use file.io, Gofile or Filebin instead.

#5

tmpfiles.org

Best for: Simple browser uploads

Visit tmpfiles.org

tmpfiles.org, branded as /tmp/files, is a temporary file upload service with a plain upload page: upload files up to 100 MB, with all files deleted after a set period. Its homepage points users to OnlyFiles for permanent file hosting, making the split clear: tmpfiles for quick shares, OnlyFiles for longer storage.

For Catbox users who want a no-fuss browser upload without accounts or settings, tmpfiles.org fits, though its thin homepage means expiry details should be confirmed on the site before sharing anything time-sensitive.

#6

Filebin

Best for: No-registration sharing

Visit filebin.net

Filebin offers convenient file sharing in three steps without registration: select files or drag and drop them into the browser window, wait for uploads to complete, and share the resulting link. Uploaded files can be deleted manually at any time and are deleted automatically 6 days from upload.

That 6-day window sits between Uguu's 3 hours and 0x0.st's 30-day minimum, making Filebin a balanced choice for shares that need to last a few days. Note that uploads cancel if you move away from the page before they complete, so keep the tab open until the share link appears, and use the manual delete option promptly if a link was shared with the wrong recipient.

#7

OnlyFiles

Best for: Simple permanent-style sharing

Visit onlyfiles.com

OnlyFiles is simple file sharing from the same operator as tmpfiles.org, positioned as the option for permanent file hosting where tmpfiles is temporary. Its upload page accepts files up to 100 MB, with all files deleted after a set period according to the page shown.

For Catbox users who want a simple permanent-style host without accounts, OnlyFiles is worth testing, though its thin homepage means retention and management details should be confirmed on the site before relying on it for important files.
