A competitor teardown from Ruzuku put the premise better than I can, so I will just quote it.
“Your subscribers, your content, and your community history are tied to the platform. Before you build there for three years, test the exit.”
That sentence is the whole post. What follows is the test, run against every major platform's documentation and support record as of July 2026. As far as I can tell, nobody has published this comparison before, which is itself informative... export is the feature every platform hopes you never ask about.
The scorecard
| Platform | Member list | Posts + comments | Courses | How you get it |
|---|---|---|---|---|
| Skool | CSV with emails, self-serve | No path at all | No path at all | Dashboard export (members only) |
| Circle | CSV, self-serve | Support-assisted CSVs, images excluded | Partial via support | Ask support, sometimes for weeks |
| Mighty Networks | .xlsx on Launch and up | No bulk export | Tricky at best | Dashboard (members only) |
| Facebook Groups | Nothing sanctioned | Nothing | n/a (Units deprecated) | There is no door |
| Heartbeat | CSV on request | CSVs on request | On request | Support ticket only |
| Nas.io | None documented | None documented | None documented | We could find no documented path |
| Discourse | Full | Full | n/a (forum) | One-click full site backup + REST API |
| Seedly Communities | Yours already | Yours already | Yours already | You hold the database |
Compiled from each platform's help documentation and review record, July 2, 2026. Export policies change quietly, re-verify before betting a migration on any row.
Skool, the one-way door
Skool exports a members CSV with email addresses, including for paid groups, and credit for that. It is the end of the list. Posts, comments, community history, and course content have no export path at all, and there is no public API to build one with. Third parties sell scraping tools for exactly this reason. Years of discussion and coursework live behind a door that does not open. Full pricing context in the Skool teardown and the vs page.
Circle, best of the big three
Circle earns a genuine concession here. Member CSV is self-serve, and support will assemble a fuller export of members, spaces, posts, and comments as CSVs on request. Two caveats from the record. Post images are excluded, and some creators describe chasing support for weeks to get the export delivered. An exit that depends on a support queue is a real exit with a real asterisk. Costs and add-ons are covered in the Circle teardown and the vs page.
Mighty Networks, members only
Mighty exports a member .xlsx on Launch plans and up. Posts and discussions have no bulk export, and moving course material is widely described as tricky. The sharper story came out of the UK, where a host dealing with Online Safety Act compliance reported being locked out of the network they created without being given a simple admin-only export route before being cut off. An export you cannot reach when it matters is not an export. The Mighty vs page has the full comparison.
Facebook Groups, nothing
There is no sanctioned way to export member emails, content, or anything else. Scrapers violate the terms of service. Meta owns the group, the list, and the relationship, a fact the June 2025 mass bans made expensive for thousands of admins in one night. See also the Facebook Groups vs page.
Heartbeat and Nas.io, the fine print tier
Heartbeat will export posts, comments, docs, and members as CSVs, but only through a support ticket. Not self-serve, so factor the dependency in. Nas.io is the one that should stop you. We could find no documented export path of any kind as of July 2026. I am phrasing that carefully, absence of documentation rather than confirmed absence of the feature, but if the exit exists, they have chosen not to write it down.
Discourse, the gold standard
Praise without reservation. Discourse offers one-click full site backups, a complete REST API, and an open-source codebase. You can take everything, any time, no ticket, no permission. This is the bar every platform in this table should be measured against, ours included.
The honesty section
Two concessions before the pitch paragraph. First, Circle really is meaningfully better than its big-three peers here, and if you are choosing between rented platforms, its export story should weigh in its favor. Second, the Seedly Communities row deserves scrutiny too. “You hold the database” is only as good as your own habits. When you own the deployment, backing up your Convex data and keeping your deploy keys safe becomes your responsibility, and nobody is coming to do it for you. Ownership is not a magic word, it is a chore list. A short one, but real.
With that said, the structural point stands. On Seedly Communities there is nothing to export because nothing ever left your control. Members, posts, courses, and payment relationships live in your database, under your accounts, from day one.
How to test the exit before you commit
- Ask support for a full export in writing before you sign up, and keep the reply.
- Search the help docs for the word “export” and read what is actually offered, not what the sales page implies.
- Search Trustpilot reviews of the platform for “export” and read what happened to people who tried.
- Confirm exactly what happens to member emails, since the member relationship is the asset everything else hangs off.
FAQ
Can I export my Skool posts and courses?
Does Circle's export include images?
Can Facebook group admins get member emails?
Before you build there for three years, test the exit. If the answer to “can I leave” is a support ticket, a scraper, or a shrug, you already know what you are renting. The version of this where the exit door is your own database is covered in the ownership pillar guide.
