CryptPad vs Seafile
Both are alternatives to Google Drive. Here's how they stack up — verified facts, no spin.
Also searched as Seafile vs CryptPad — same comparison, one verdict.
CryptPad keeps your data local by default and Seafile keeps it in the vendor's cloud — for most teams that single fact decides it.
CryptPad
End-to-end-encrypted collaborative documents where the server never sees your content.
CryptPad is a privacy-first collaboration suite built around end-to-end encryption: documents, spreadsheets, presentations, and more are encrypted in your browser, so a self-hosted or public server stores only ciphertext and cannot read your content. It supports real-time co-editing, shared folders, and a range of app types, and it is AGPL-3.0 licensed and self-hostable via Docker or a Debian install. Developed by XWiki SAS with public-interest funding, it also runs a free public instance at cryptpad.fr. It is the strongest choice when confidentiality is the priority; the trade-off is that it is a distinct web workspace rather than a drop-in Microsoft-format editor.
Seafile
Fast, reliable self-hosted file sync and share.
Seafile is an open-source file-sync-and-share platform known for fast, reliable syncing and client-side encryption options. Its Community Edition is self-hostable and a strong choice when raw sync performance matters.
Side by side
10 points of comparison, every one read from a verified field. Green marks the side that wins a row outright. A dash means we do not hold that fact — never that it is zero.

| Sovereignty ScoreOur transparent 0–100 composite for data ownership and exit cost. | 92 | 86 |
| Open source | Yes | Yes |

| Pricing | Free / self-host; free public instance at cryptpad.fr | Free self-host (Community Edition); paid Pro tier |
| RAM to run it wellThe figure that actually matters, not the vendor's minimum. | 2 GB for a small instance | 4 GB |
| Realistic running costWhat the box costs each month if you run it yourself. | $12–20/mo on a small VPS | $18–30/mo, against Dropbox Business per-seat pricing |
| Setup timeHonest first-install estimate, not the marketing quickstart. | 2 hours, and the two-domain requirement is the hard part | 2 hours |
| Ongoing maintenanceThe part nobody budgets for. | Moderate. Version pruning is a job you have to schedule. | Moderate. Its garbage collector must be run periodically or deleted data never actually frees space. |
CryptPad edges it on the Sovereignty Score, but the right pick depends on the trade-offs below.

CryptPad
Strengths
- +AGPL-3.0 licensed and self-hostable via Docker or Debian, so you can own the whole stack
- +End-to-end encryption means the server stores only encrypted data and cannot read your documents
- +Real-time collaborative documents, spreadsheets, presentations, and shared drives in the browser
- +A free public instance (cryptpad.fr) lets you try it with no setup
- +Actively maintained by XWiki SAS with sustained public-interest funding
Trade-offs
- −It is a browser-based encrypted workspace, not a full desktop suite or a drop-in Microsoft-format editor
- −Compatibility with complex Microsoft documents is more limited than ONLYOFFICE or LibreOffice
- −The encryption model means account recovery and some integrations work differently from conventional suites
- −Self-hosting requires running a server, and encrypted real-time editing is heavier than plain document storage
Seafile
Strengths
- +Fast, reliable sync engine
- +Client-side encryption option
- +Mature clients
Trade-offs
- −Some features are Pro-only
- −Smaller app ecosystem than Nextcloud
Which one fits you
The trade-offs above, turned into a decision. Find the line that describes your team.
Choose CryptPad
if your data should stay on machines you control, and aGPL-3.0 licensed and self-hostable via Docker or Debian, so you can own the whole stack.
Choose Seafile
if fast, reliable sync engine.
Neither, yet
if both carry a real cost you should weigh first — it is a browser-based encrypted workspace, not a full desktop suite or a drop-in Microsoft-format editor, and some features are Pro-only. If either of those is a dealbreaker for your team, the shortlist is wrong rather than the choice.

CryptPad vs Seafile — common questions
Is CryptPad a better fit than Seafile for cloud storage & sync?
It depends on what you are optimising for, and the honest split is this: CryptPad scores 92 to Seafile's 86 on data ownership and exit cost, so it is the safer choice if you care about being able to leave. Seafile earns its place on a different axis — fast, reliable sync engine. Neither is a wrong answer for every team; the table above is the actual comparison.
What happens if we want to switch later?
CryptPad keeps its data local or in open formats, so leaving is an export rather than a negotiation. Seafile is still self-hostable, so the files stay on your server either way — but it is not local-first by design, so check what its export produces before you rely on it.
Can I self-host CryptPad or Seafile?
Both can be self-hosted. The difference is what it costs you in time rather than whether it is possible — see the setup and maintenance rows above.
Are CryptPad and Seafile both alternatives to Google Drive?
Yes — both appear in our Google Drive comparison, which is why they are worth putting side by side. People usually arrive here already having decided to move off Google Drive and now choosing between the two replacements, which is a narrower and much easier question.
