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, 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. 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 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, dashboard, widget, 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?
Customers can follow the requests and roadmap initiatives they care about and get notified when those move. Crumb ranks demand by the accounts and ARR behind a request rather than by vote count alone.
Can I move my Fider data to Crumb?
Crumb has a public API for importing items, accounts, and votes, and Fider has an API for exporting. A guided migration is on the roadmap; get in touch and we'll help.
