How do the open source alternatives compare?
| Option | Licence | Really costs | State |
|---|---|---|---|
| Fider | AGPL-3.0 | $6 to $12/mo hosting | Actively maintained |
| LogChimp | AGPL, open core | Hosting, plus $24/mo for boards | Active, thin team |
| ClearFlask | Apache-2.0 | Hosting | Alive, very small |
| Astuto | AGPL-3.0 | n/a | Archived, do not use |
| GitHub Issues | Hosted, not open source | Nothing on public repos | Not going anywhere |
| Docket | Bought, source included | $99 once | Ours |
Licences and prices re-checked against Fider's, Astuto's, LogChimp's and ClearFlask's own licence files on 23 August 2026. Hosting estimates assume one small VPS and a free-tier email sender.
Going through the options
Fider, and start here
AGPL-3.0, 4,475 stars, last pushed 9 August 2026, with v0.36.1 released on 3 July. It gives you voting, a public roadmap, private boards and your own domain. You supply Docker, PostgreSQL 12 or later, and an SMTP, Mailgun or SES sender, which realistically means a small VPS at around $6 to $12 a month all in. Two catches. There is no changelog feature at all, which for a lot of people is half the reason they wanted one of these. And the security work is yours: v0.35.0 fixed a critical authentication vulnerability, v0.36.0 fixed SSRF and cross-site scripting, and v0.36.1 was more of the same, all inside three months. Nobody emails you when one lands.
Best for: A developer who is comfortable running Docker, PostgreSQL and a mail sender, and wants no licence cost at all.
Not for: Anyone who needs a changelog, which Fider does not have, or who would rather not be the one applying security patches.
Astuto, which is dead
The repository was archived and made read-only on 8 February 2026. The maintainer posted his own end-of-life notice and now points people at Fider. The hosted version ran for under a year and shut down, and the last meaningful release was March 2025. It still ranks well and it is still recommended in older roundups, which is exactly why it is worth saying plainly: do not start here in 2026. A Rails and Node dependency stack with no more security patches is a liability, not a saving.
Best for: Nothing in 2026. The repository was archived and made read-only on 8 February 2026 and the maintainer now points people at Fider.
Not for: Any production use at all. A Rails and Node stack with no more security patches is a liability rather than a saving.
LogChimp, which is open core
Genuinely active, last pushed 20 August 2026, and AGPL-3.0 as far as the licence file goes. The catch is what sits behind the paid tier, and it is not a nicety: Boards, Roadmaps and Comments are Pro-only at $24 a month billed yearly, on the self-managed build as well as the cloud. The free self-hosted version gives you posts, customers, one admin role and a custom domain. Calling that a free and open source feedback board is a stretch, since the parts that make it a feedback board are the parts you pay for.
Best for: A team that wants posts, customers and a custom domain self-hosted, and is happy to pay for the rest.
Not for: Anyone expecting a free feedback board. Boards, Roadmaps and Comments are Pro-only at $24 a month billed yearly, on the self-managed build as well as the cloud.
ClearFlask
Apache-2.0, 448 stars, last pushed 5 August 2026. Alive, and a permissive licence rather than a copyleft one, which matters to some buyers. Very small though, and a project this size is a bet on one or two people continuing to care.
Best for: A buyer who needs a permissive Apache-2.0 licence rather than copyleft, and can accept a very small project.
Not for: Anyone who needs to know the project will still be maintained in three years. At 448 stars it rests on one or two people continuing to care.
GitHub Issues and Discussions
Not open source, but free on public repositories and worth including because so many teams try it first. Nothing to host, nothing to patch, GitHub absorbs the spam, and the threaded email is better than most paid tools manage. It has one hard problem as a customer-facing surface: posting requires a GitHub account, which most buyers of a consumer app do not have and will not create. There is also no changelog, no real voting beyond reactions, and every complaint is public, permanent and indexed against your product's name.
Best for: A developer tool whose customers already have GitHub accounts and live in the same repository.
Not for: Any consumer-facing product. Posting requires a GitHub account, there is no changelog and no real voting, and every complaint is public, permanent and indexed against your product's name.
Docket, $99 once
Ours, so read it knowing that. Not open source, but you get the source and you own your copy, on your own domain. The relevant difference from everything above is that there is no database and no server, so there is nothing to stand up, patch or back up, and no CVE to notice. It ships a changelog, which Fider and LogChimp do not, and scheduled jobs that draft the replies and write it for you.
Open it and compare.
Best for: One person or a small team shipping software who wants the board, roadmap, changelog and FAQ on their own domain, paid for once.
Not for: Anyone who wants a vendor to run it for them. There is no hosted version, you set it up in your own GitHub account, and it is newer and smaller than Canny or Productboard.
Which open source alternative should you choose?
Three questions, and they settle almost every case.
- "Free" is a licence, not a bill. A small VPS and a mail sender is $6 to $12 a month, which is $216 to $432 over three years. That is real, and it is still less than every hosted tool here.
- Who applies the security patches? Fider shipped three security releases in three months. If nobody on your side is watching that repository, self-hosting is a risk you are taking rather than a cost you are saving.
- Do you need a changelog? Neither Fider nor LogChimp has one. If telling customers what shipped is half the point, that rules out most of this page.
