Snappymail vs Cypht: Which Should You Self-Host?
Quick Verdict
Snappymail is the better webmail client for most people. It’s faster, more polished, and handles a single email account exceptionally well. Cypht is the right choice if you need to aggregate multiple IMAP accounts and RSS feeds into one unified inbox — a niche feature that Snappymail and Roundcube don’t offer.

Overview
Snappymail (formerly RainLoop) is a fast, modern webmail client focused on a single-account experience with a clean UI, keyboard shortcuts, and excellent search. It’s the most performant self-hosted webmail option.
Cypht is a lightweight webmail aggregator that combines multiple IMAP accounts, RSS feeds, and ATOM feeds into a single interface. It’s designed for users who manage several email accounts and want a unified view.
Feature Comparison
| Feature | Snappymail | Cypht |
|---|---|---|
| Multi-account | Switch between accounts | Unified inbox across accounts |
| RSS/ATOM reader | No | Yes (built-in) |
| IMAP support | Full | Full |
| SMTP support | Full | Full |
| PGP encryption | Yes (OpenPGP.js) | No |
| S/MIME | Yes | No |
| Search | Fast, server-side IMAP search | Basic search |
| Keyboard shortcuts | Extensive | Basic |
| Theme support | Multiple themes + custom CSS | Light/dark only |
| Admin panel | Yes (web-based) | No (config file) |
| Contacts | Built-in + CardDAV sync | Basic address book |
| Calendar | No (planned) | No |
| Plugins | Yes (extensible) | Modular components |
| Mobile responsive | Yes | Yes |
| Dependencies | PHP 8+ | PHP 8+ (bundled via Docker) |
| Database | None required (file-based) | MariaDB/MySQL |
| Docker image size | ~50 MB | ~200 MB |
| RAM usage | ~30 MB | ~80 MB |
| License | AGPL-3.0 | GPL-2.0 |
Installation Complexity
Snappymail has the simpler Docker setup — one container, no database required. Configuration happens through the web admin panel at /admin. Connect it to your IMAP/SMTP server and you’re done.
Cypht ships as a Docker image with Nginx, PHP-FPM, and MariaDB bundled via supervisord. First-time setup creates an admin account automatically. Adding IMAP accounts happens through the web UI after login. The bundled approach means more components but everything works out of the box.
Performance and Resource Usage
| Metric | Snappymail | Cypht |
|---|---|---|
| RAM (idle) | ~30 MB | ~80 MB |
| RAM (active) | ~60 MB | ~120 MB |
| CPU | Very low | Low |
| Page load time | Fast (optimized JS) | Moderate |
| Large mailbox handling | Excellent | Adequate |
Snappymail is noticeably faster, especially with large mailboxes. Its JavaScript frontend is optimized for performance. Cypht’s multi-account aggregation adds overhead — it queries multiple IMAP servers simultaneously.
Community and Support
| Aspect | Snappymail | Cypht |
|---|---|---|
| GitHub stars | 3,000+ | 1,000+ |
| Active development | Very active | Active |
| Documentation | Good (GitHub wiki) | Adequate (docs site) |
| Community size | Medium | Small |
| Update frequency | Monthly releases | Quarterly releases |
Snappymail has stronger community momentum and more frequent updates. Cypht has a smaller but dedicated user base, particularly among users managing multiple email accounts.
Use Cases
Choose Snappymail If…
- You primarily use one email account
- You want the fastest webmail experience
- You need PGP/S/MIME encryption support
- You want an admin panel for easy configuration
- You prefer a polished, modern UI with keyboard shortcuts
- You need CardDAV contact synchronization
Choose Cypht If…
- You manage multiple email accounts and want a unified inbox
- You also want RSS/ATOM feed reading alongside email
- You prefer a lightweight, no-frills interface
- You want all your information sources in one place
- You’re comfortable with config-file-based administration
Final Verdict
Snappymail is the better webmail client for the majority of users. It’s faster, more feature-rich, and easier to configure. The PGP support, admin panel, and performance optimization make it the go-to self-hosted webmail choice.
Cypht fills a specific niche: if you manage 3-5 email accounts across different providers and also follow RSS feeds, Cypht’s unified aggregation view saves real time. No other self-hosted webmail client does this. But if you only need one or two accounts, Snappymail (or Roundcube for a more traditional experience) is the better choice.
