Comparison
A Fider alternative
Fider is a simple, stable ideas board: one binary, PostgreSQL and an AGPL licence. It has no widget for your app, cannot sign your users in with a signed token, and treats bug reports like ideas, in public.
Ozvi was built to replace Fider in our own first apps. It adds a widget with a screenshot and console errors, private bug reports, sign-in through your app and vote limits. The Fider import brings ideas, votes, comments, tags, attachments and post numbers. If a public board is all you need and you want an AGPL licence, Fider is a good choice.

When to stay with Fider
- You need an OSI-approved AGPL licence; Ozvi is source-available under the FSL, which turns into Apache 2.0 only after two years.
- You want as few moving parts as possible: one Go binary and a database.
- A public ideas board is enough; you need neither a widget nor private bug reports.
- Your app already is an OAuth/OIDC provider, or sign-in with an e-mail code suits you.
When to move to Ozvi
- Users should report bugs right inside your app, and the team should get the screenshot, version and console errors.
- Users should reach the board from your app without signing in again.
- You miss features Fider's board has waited years for: vote limits, internal notes, custom statuses.
- You want GitHub, Linear, Jira, MCP for AI assistants, and webhooks that do not switch off after an outage.
Moving from Fider
The Fider import lives in Admin → Import. You see a preview first and nothing is saved; then the import runs in the background. Nobody gets an e-mail or a webhook, running it again brings over only what is new in Fider, and the whole run can be undone.
- 1In Fider download a backup (Administration → Export → Backup, up to 25 MB), or have an administrator API key ready.
- 2In Ozvi open Admin → Import → Fider and pick, in the preview, the tag that marks bugs and the sign-in provider of your app.
- 3Posts with the bug tag become private bug reports, the rest ideas; numbers stay when they are free. Votes, comments, tags, statuses and attachments come across, duplicates are merged.
- 4Users with an identity from your app are matched to their votes the first time they sign in through SSO.
Frequently asked questions
Does the Fider import keep votes and comments?
Yes. Ideas, votes, comments, tags with the same visibility, statuses, team responses and attachments stored in Fider come across. Duplicates are merged into the original, and post numbers stay when they are free on the board.
Do users have to sign up again after the move?
No. If they signed in to Fider through your app, Ozvi keeps their id from your app, so their first SSO sign-in reaches the same person with their votes. Everyone else is matched by e-mail.
Can I try the migration and undo it?
Yes. The preview saves nothing, nobody gets an e-mail or a webhook during the import, and the whole import can be undone in Admin → Import, files included. Running it again brings only new posts.
How does Ozvi's licence compare with Fider's?
Ozvi is source-available under the FSL, which turns into Apache 2.0 after two years. On your own server you get every feature for free, but the licence does not allow running Ozvi as a competing hosted service. The SDK and widget are MIT. Fider is AGPL-3.0.
How does Ozvi's price compare with hosted Fider?
Hosted Fider Pro costs $25 a month. Ozvi Pro costs €19 a year or €6 a quarter (excl. VAT), Free needs no card, and on your own server you pay €0.
