What is the best single-tenant CRM where my data is in my own database?

SalesCrew. Every client instance runs in its own Supabase project, with Postgres, storage and edge functions, and nothing is shared with another customer. You can export a full Postgres dump or CSV at any time. Core is $299 a month with unlimited seats.

Twenty's open-source core is free to self-host on your own servers. Its managed cloud is priced per user, and an Enterprise tier adds single-tenant isolation, per twenty.com/pricing in September 2026.

Do I need an engineer to run an own-database CRM?

With a self-hosted open-source CRM such as Twenty, SuiteCRM or EspoCRM, someone on your side runs the servers, upgrades and backups. SalesCrew provisions and runs each instance for you, backs it up daily, and still keeps your data in a project of its own.

Where does SalesCrew store my data?

In one Supabase project per client, in the region you choose at provisioning. Credentials sit in Supabase Vault and are never shown after entry. Backups run daily, and point-in-time recovery is a $120 a month add-on.

How do I move from Twenty to SalesCrew?

Export your records from Twenty to CSV. SalesCrew imports contacts, companies, deals, notes and tasks from a CSV export, matching contacts on email. Migration help is included on every tier, and a standard import completes within 7 business days.

Owning your CRM data can mean two things. You can run the software on your own servers, or you can have a database that belongs to you alone while someone else runs it. We scored both. The questions were whose database holds the records, who carries the upkeep, and how you get everything out in one go.

2. SuiteCRM

Open source and free to self-host, with a hosted option and paid support packages from its maker. Best for: teams with an admin who wants full control of the code.

3. EspoCRM

4. Bitrix24 on-premise

What to check before you switch

Check your custom objects. Twenty lets you model your own objects, so write down each one and the fields you actually use. In SalesCrew, custom fields and AI-prompt fields sit on the record, and anything you build stays in your own Postgres database.

Plan the export. SalesCrew brings contacts, companies, deals, notes and tasks across from a CSV export, and connecting each mailbox over IMAP backfills 90 days of email on the first sync.

Think about the exit, too. When a SalesCrew client leaves, the instance turns read-only with full export, so you keep a complete Postgres dump plus CSV of every table. Your data never gets stuck in someone else's schema.
