Open source vs paid sales pipeline software

Paid cloud products usually win on polish, mobile apps, automatic bank connections and support. Open source wins on running cost as you grow, data ownership and the freedom to customize. The real cost of open source is hosting, backups, updates and your own time, so count those honestly. Several of these projects also sell hosting or support if you would rather not run a server yourself.

How to choose the best sales pipeline software

• You want a modern board: Twenty.
• You want a Pipedrive-style tool you host: warpdrive (young project).
• You are a developer: Atomic CRM.
• You want maximum features: SuiteCRM.

Mistakes to avoid

Keep stages few and clear, and review the pipeline weekly. A pipeline is only useful if it reflects reality.

Where to host it

All of these tools can be self-hosted. A small VPS or a web hosting plan from a provider such as Hostinger is enough to get started with most of them. Check each project's requirements first, and read our security and backup checklist before you add real data.
