Hey Product Hunt! 👋 I'm the creator of The AltStack.
We built The AltStack because the SaaS landscape has gotten out of control. Teams are paying hundreds of dollars per seat for communication tools, CRMs, and project management platforms that they don't actually own. When prices go up, you just have to pay.
There is a massive, thriving open-source ecosystem building enterprise-grade tools that run on a fraction of the hardware cost. The problem isn't that the tools don't exist; it's that discovering them, comparing them accurately, and figuring out how to deploy them securely is a massive headache.
So we built the engine we wished existed:
🔍 Discover: 460+ open-source tools across 30 categories.
⚔️ Compare: Unbiased, side-by-side comparisons (e.g., Slack vs. Mattermost).
💸 Calculate: A built-in Savings Calculator to see how much you're bleeding to SaaS.
🐳 Deploy: 59+ tools (and growing) have production-ready, one-click Docker Compose configurations.
100% of our tool data is open-source on GitHub too.
We'd love to hear your thoughts! What's the proprietary SaaS tool you're most desperate to replace? Let me know in the comments! 👇
