ClosaraOpen-source and self-hosted Streak alternatives
Streak is a CRM in a Gmail tab. Closara is a CRM on your server that talks to Gmail.
The open-source CRMs that replace Streak
Streak 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 Streak bills
Per user, grafted directly into Gmail. Tiers unlock mail merge, reporting and sharing, and assume the whole team is on Google.
What keeps you on Streak
Lock-in is almost never a contract clause. It is accumulated work you cannot take with you.
- The CRM lives inside Gmail: if part of the team does not use Gmail, check how they would access it.
- Information sharing depends entirely on Google permissions.
- No self-hosting option.
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 Streak to Closara
Pipelines export to CSV; the attachment to Gmail threads stays in Gmail.
- Read before writing: a full Streak 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 Streak 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 Streak
If your team refuses to open any tab but Gmail, Streak is the only credible answer.
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 Streak?
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 Streak open source?
No. Streak 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 Streak?
No. No edition of Streak 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 Streak to Closara?
Pipelines export to CSV; the attachment to Gmail threads stays in Gmail. 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 Streak?
It depends on your headcount, and we do not quote their prices: they change. Streak 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 Streak?
Pipelines export to CSV; the attachment to Gmail threads stays in Gmail.
When should you stay on Streak?
If your team refuses to open any tab but Gmail, Streak is the only credible answer. We would rather say it plainly: a failed migration costs more than a subscription.
