Open-source alternatives to Pipedrive
Pipedrive is a sales CRM for small teams with AI sales assistant features. If you would rather own the software, keep data on your own server or avoid per-seat pricing, these open-source tools tackle the same problem: close more sales. Most deals aren't lost, they're forgotten. Clean pipelines, fast follow-up and frictionless signatures close the gap.

Hosted vs open source: what changes
Open source swaps a subscription for setup time. Pipedrive is hosted, supported and updated for you; with the tools below you (or someone you hire) install, update, back up and secure them. 0 of the 5 with a setup rating here need a developer. Most can also be bought as a hosted cloud plan from the same maintainers, which is a good middle path. Check each licence before you build on it.
