Crumb vs Fider

A Fider alternative for B2B teams.

Fider is a great open-source voting board. Crumb is open source too, and built for B2B SaaS teams: capture feedback inside your product, see the revenue behind each request, push work to Linear, Jira, or GitHub, and tell customers when it ships.

When Crumb is the better fit

Your customers are companies, not voters

On a public board, every vote counts the same. In B2B, a request from an account paying $48k a year and one from a free trial aren't equal. Crumb attaches each request to the account and its ARR, set by hand or synced from HubSpot or Salesforce, so you can see what's at stake.

You want feedback from inside your product

Crumb's widget is one <script> tag, identified by a short-lived token your server signs. Customers send feedback without leaving your app, and it arrives already tied to their account. Email, Slack's /crumb command, and the API land in the same inbox.

You want the work to reach engineering

Push a request to Linear, Jira, or GitHub as a ticket, and the status syncs back. When it ships, everyone who asked through the widget hears about it.

When Fider is the better fit

If you want a simple public voting board for an open-source project or a consumer app, and don't need revenue context or tracker sync, Fider is lighter to run and does that job well.

Frequently asked questions

Is Fider open source like Crumb?

Yes. Both are AGPL-3.0 and self-hostable with Docker and Postgres. The difference is scope: Fider is a focused public voting board, and Crumb covers the full loop from in-app capture to revenue-based triage to your tracker and back to the customer.

Is Crumb harder to run than Fider?

Not much. Crumb's whole stack (the dashboard, the widget it serves, and Postgres) comes up from one docker compose file. Fider is a single Go service plus Postgres, so it's slightly lighter.

Does Crumb have voting?

No. Customers hear back on the requests they sent and can follow the roadmap initiatives they care about, with a notification when those move. Crumb ranks demand by the accounts and ARR behind a request instead of by votes.

Can I move my Fider data to Crumb?

Yes, though there's no one-click importer. Export your posts with Fider's API, import your accounts under Settings → Account mapping, then post each request to Crumb's Capture API (POST /api/v1/captures). Get in touch if you'd like a hand.
