DBaaS / Serverless Databases
The biggest real split between MongoDB Atlas and PlanetScale is lock-in posture: MongoDB Atlas carries medium lock-in (medium — mongodb query language proprietary ( sql), but mongodump standard), while PlanetScale carries low lock-in (low-medium — standard mysql (vitess), but branching = proprietary feature). That single fact shapes the rest of the comparison. MongoDB Atlas is built for apps, global and is not a fit for simple, offline projects. PlanetScale is built for apps, global and is not a fit for simple, offline projects. On the scoring side, MongoDB Atlas rates 5/5 for developer experience and 4/5 for transparency; PlanetScale rates 5/5 and 4/5 respectively. The honest trade-off: with MongoDB Atlas you accept that simple key-value storage needs, while PlanetScale comes with the reality that simple key-value storage needs. Neither side is free. MongoDB Atlas's headline strength in the data is that apps needing managed database. PlanetScale's headline strength is that apps needing managed database.
Quick take
MongoDB Atlas is for apps, global; PlanetScale is for apps, global; decide based on lock-in tolerance.

Medium — MongoDB query language proprietary ( SQL), but mongodump standard
Migration difficulty: medium
Data you keep: mongodump/mongorestore
API standard: MongoDB Wire Protocol
Risk notes: Medium — MongoDB query language proprietary ( SQL), but mongodump standard
💡 Moderate effort required. Export data before canceling
Low-Medium — standard MySQL (Vitess), but branching = proprietary feature
Migration difficulty: low
Data you keep: SQL export
API standard: MySQL-compatible
Risk notes: Low-Medium — standard MySQL (Vitess), but branching = proprietary feature
💡 Standard protocols make switching straightforward
Choose MongoDB Atlas if you are apps, global and can accept medium lock-in (medium — mongodb query language proprietary ( sql), but mongodump standard).
Not for: Simple, Offline projects
Choose PlanetScale if you are apps, global and need low lock-in (low-medium — standard mysql (vitess), but branching = proprietary feature).
Not for: Simple, Offline projects

Both list a hybrid pricing model in our data; MongoDB Atlas has a free tier and PlanetScale does not. We don't have per-seat numbers in this dataset, so 'cheaper' depends on volume. Price both on your actual usage before deciding.
MongoDB Atlas has medium lock-in (medium — mongodb query language proprietary ( sql), but mongodump standard); PlanetScale has low lock-in (low-medium — standard mysql (vitess), but branching = proprietary feature). Migration effort scales with how much state and automation you've built in MongoDB Atlas; plan for data export, config rebuild, and a parallel-run period before cutting over.
Both MongoDB Atlas and PlanetScale score 5/5 on developer experience in our data, so DX isn't the tiebreaker here. Decide on fit, pricing, or lock-in instead.
PlanetScale is built for apps, global and explicitly not for simple, offline projects, so it's a fit only if your workflow matches its stated audience. If you were using MongoDB Atlas for apps, global, the switch is reasonable; outside that scope, look elsewhere.
