ClosaraOpen-source and self-hosted Brevo alternatives
Brevo hosts in Europe. Closara installs at YOUR place, on your server.
The open-source CRMs that replace Brevo
Brevo 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 Brevo bills
By email volume sent rather than per contact; the CRM is one brick among several, and each brick (marketing, conversations, transactional) has its own meter.
What keeps you on Brevo
Lock-in is almost never a contract clause. It is accumulated work you cannot take with you.
- Deliverability runs through their infrastructure: switching means warming a domain elsewhere.
- Bricks are sold separately and add up.
- Vendor-hosted: check the region in its documentation.
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 Brevo to Closara
Contacts and lists export well; deliverability history does not travel.
- Read before writing: a full Brevo 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 Brevo 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 Brevo
If email volume is your business and European hosting is enough, Brevo is solid and good value.
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 Brevo?
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 Brevo open source?
No. Brevo 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 Brevo?
No. No edition of Brevo 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 Brevo to Closara?
Contacts and lists export well; deliverability history does not travel. 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 Brevo?
It depends on your headcount, and we do not quote their prices: they change. Brevo 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 Brevo?
Contacts and lists export well; deliverability history does not travel.
When should you stay on Brevo?
If email volume is your business and European hosting is enough, Brevo is solid and good value. We would rather say it plainly: a failed migration costs more than a subscription.
