Open source isn't just free software. It's freedom from vendor lock-in, artificial limits, and surprise price hikes.
With SaaS, your data lives on someone else's servers under their terms. With open source, your stack runs on a VPS you control. If we disappear tomorrow, your system keeps running. That's the opposite of vendor lock-in.
SaaS tools punish growth: more contacts = higher tier, more users = more seats, more automations = more tasks. Open source has no built-in limits. You pay for infrastructure, not artificial scarcity.
Every tool in our stack is open source. You can inspect the code, verify security practices, and know exactly how your data is processed. No black-box algorithms or hidden data sharing.

Open source tools are maintained by global communities, not single companies that can pivot, raise prices, or shut down. Mautic, Twenty, Chatwoot, Activepieces, and Metabase all have active, growing communities.
Open source is free to download, but expensive to maintain. You need someone to:
That's where SourceStack comes in. We handle the infrastructure so you can focus on your business.
