Many providers, one login
Add mailboxes from any provider. Each keeps its own folders and color, and one PIN unlocks them all.
Self-hosted webmail
Webmail on your own server, for every mailbox you have.
Peep Web is a PHP webmail suite you install on your own Linux server. It isn't tied to one mail server: Gmail, AOL, Yahoo, iCloud, Outlook.com, your ISP and your own domains all sit side by side behind one PIN.
Why people switch
Built for people who run their own server
Unzip it into your web root, run one setup command and set a PIN. Peep checks your server and tells you exactly what's missing.
Real push mail
A small background service holds an IMAP IDLE connection to every mailbox, so new mail shows up at once and providers see few logins.
Easy on the server
Apache and PHP 8.1 with SQLite built in. No separate database server and no Node.js.
Server check with the fix
Peep checks PHP extensions, the data folder, HTTPS, SELinux and the push service, and gives the exact dnf or apt command for anything missing.
A Windows app that links to it
Peep for Windows can use your server's mailboxes, rules, calendar, contacts and notes, with an offline copy.
More than mail
Calendar with invites, tasks, notes, an address book and rules, all stored on your server.
Side by side
Roundcube or Peep
Roundcube is the best-known self-hosted webmail. Both are PHP, both are free; they're built for different jobs.
| Roundcube | Peep Web | |
|---|---|---|
| Price | Free, open source | Free |
| Mailboxes from different providers in one login | No, one IMAP account per login | Yes |
| New mail pushed without a browser open | No | Yes, with the push service |
| Calendar | With a plugin | Built in |
| Tasks and notes | With plugins | Built in |
| Desktop app that links to it | No | Yes, Peep for Windows |
| Plugin library | Yes, a large one | No |
| Database | MySQL, PostgreSQL or SQLite | SQLite, built in |
| Usually installed alongside | Your own mail server | Any mail provider |
To be fair: Roundcube is the better fit when you run your own mail server for many users and want its plugin library. Peep Web is built for one person or household reading many mailboxes from many providers. For a business, see Peep Enterprise.
