FAQ

Questions about these comparisons.

Who writes these comparisons?

The MoonDive team, the engineers who build with these frameworks, clouds and databases on client and in-house projects. Each comparison sets out the trade-offs we look at when we choose a stack for a product.

How should I use a comparison?

Start with the scenario that matches your situation in "Which one fits", then read the feature table for the details that matter to you. The strengths and trade-offs show what you give up with each option.

Is one option always the better choice?

Rarely. Most of these options are good at different things, so the right pick depends on your team, budget, timeline and users. Each comparison gives a recommendation per scenario rather than one winner.

Can MoonDive help us choose a stack for our product?

Yes. Tell us what you are building and we can walk through the options with you, usually as part of scoping a project. Send us a short project brief to start.
