ClosaraOpen-source and self-hosted Salesflare alternatives
Salesflare reads your inbox from its cloud. Closara reads it from your server.
The open-source CRMs that replace Salesflare
Salesflare is proprietary software offered as SaaS: it does not install on your server. These CRMs do; the licence is read from their public repository.
| CRM | Licence | Language | Source code |
|---|---|---|---|
| EspoCRM | AGPL-3.0 | PHP | github.com/espocrm/espocrm |
| SuiteCRM 8 | AGPL-3.0 | PHP | github.com/SuiteCRM/SuiteCRM-Core |
| Odoo Community | LGPL-3.0 | Python | github.com/odoo/odoo |
| Twenty | AGPL-3.0 (some files under a commercial licence) | TypeScript | github.com/twentyhq/twenty |
| Closara | Proprietary, source code delivered (not an OSI licence) | Node.js, SQLite | - |
Licences checked on 2026-09-24 in each public repository's licence file. All of them install on your own server; so does Closara, but its code is delivered under a proprietary licence.

How Salesflare bills
Per seat, across several tiers, with automatic data capture as the core argument. Check which enrichment and email-finding credits are included or billed on top.
What keeps you on Salesflare
Lock-in is almost never a contract clause. It is accumulated work you cannot take with you.
- Automatic capture depends on full access to your inbox and calendar.
- Enrichment credits are a second currency.
- Vendor-hosted.
What Closara does instead
- On your server, not in their cloud
- No per-seat subscription
- The AI runs locally
- White-label included
- The code and the database are yours
Details, the demo and pricing are on the Closara page.
Migrating from Salesflare to Closara
Data exports; however, the history it rebuilt automatically from your mail does not travel: it will be rebuilt elsewhere, differently.
- Read before writing: a full Salesflare export is loaded read-only into Closara. Nothing is deleted on their side, nothing is irreversible.
- One week in parallel: the team works in both tools for seven days. Deliberately short: beyond that, nobody keeps it up and the data diverges.
- Move the users: accounts move to Closara, running sequences are replayed at the same cadence, meetings follow.
- Cancel, not before: the Salesflare subscription stops once a full week has run without falling back. Keep a dated export: that is your safety net.
When you should stay on Salesflare
For a small B2B team that hates data entry and lives in the inbox, Salesflare saves real time.
We would rather lose a sale than install a tool nobody will use. A migration costs team time, and that time never comes back.
Frequently asked questions
Is there an open-source alternative to Salesflare?
Yes: EspoCRM (AGPL-3.0), SuiteCRM 8 (AGPL-3.0), Odoo Community (LGPL-3.0) and Twenty (AGPL-3.0, some files under a commercial licence) are open source and install on your own server (licences checked in their repositories on 2026-09-24). Closara is not open source: it is a self-hosted CRM whose code is delivered to you, with local AI and unlimited seats.
Is Salesflare open source?
No. Salesflare is proprietary software hosted by its vendor: you can export your data, but you cannot audit the code, install it in-house, or modify its code.
Can you self-host Salesflare?
No. No edition of Salesflare installs on your infrastructure. If self-hosting is your criterion, the answer is not to negotiate with them but to change tool category.
How do you migrate from Salesflare to Closara?
Data exports; however, the history it rebuilt automatically from your mail does not travel: it will be rebuilt elsewhere, differently. The switch happens in four steps: pull the data read-only, run one week of outbound in parallel, move the users, then shut the old tool down. Nobody works in two tools for more than seven days.
Is Closara cheaper than Salesflare?
It depends on your headcount, and we do not quote their prices: they change. Salesflare applies its own model, described on its pricing page; Closara charges one tier plus modules, never the number of users, and hosting it yourself is free. Run the numbers with your seat count on Closara's pricing page, which compares the two models.
What data can you export from Salesflare?
Data exports; however, the history it rebuilt automatically from your mail does not travel: it will be rebuilt elsewhere, differently.
When should you stay on Salesflare?
For a small B2B team that hates data entry and lives in the inbox, Salesflare saves real time. We would rather say it plainly: a failed migration costs more than a subscription.
