Convex vs MongoDB Atlas FAQ
- Which one is cheaper?
- MongoDB Atlas is the cheaper option, starting at $0/mo vs $25/mo for Convex.
- Can I use either one for free?
- Both offer free plans, so you can try each without paying. Start with whichever fits your workflow better and upgrade when you hit the limits.
- How do they charge?
- Different approach here. Convex uses hybrid pricing, while MongoDB Atlas goes with usage-based. That changes the math depending on your team size and usage.
- Which one is a better deal?
- Depends on what you need. Convex: Convex is cheap at the entry point to hook indie devs and small teams, but that $2,500/mo floor for Business & Enterprise puts them in premium territory once you're a real company — there's almost nothing in between. They're winning developers early and betting that switching costs keep them once usage scales into serious money. MongoDB Atlas: MongoDB's undercutting itself at the low end with sub-cent hourly rates to hook indie devs and startups, while quietly pushing everyone toward Dedicated as the 'real' product — that's the tier built to compete with RDS and other managed database plays. Enterprise Advanced exists purely to capture large accounts who'd otherwise walk to Oracle or a self-hosted open-source stack, and hiding the price is a signal they're negotiating deal-by-deal rather than competing on rate card.
