Bubble and Lovable are often mentioned in the same breath: “the two big no-code options for SaaS”. Spoiler: that is not true. It is like comparing a bicycle and a Tesla because both move.
Technical comparison — the essentials
| Aspect | Lovable | Bubble |
|---|---|---|
| Stack under the hood | React + Node.js + PostgreSQL | Proprietary (Bubble bytecode) |
| Future exit | ✅ Exportable, standard code | ❌ Rewrite required |
| DB scalability | ✅ PostgreSQL = unlimited | ⚠️ Known limitations |
| Custom backend logic | ✅ Native JavaScript / SQL | ⚠️ Limited plugin system |
| Hosting | ✅ Vercel, AWS, Heroku | ❌ bubble.io only |
| Performance | ✅ A+ (optimised React) | ⚠️ B- (overhead) |
| Long-term engineering cost | ✅ Low (standard code) | ❌ High (rare expertise) |
✅ solid · ⚠️ watch out · ❌ deal-breaker
Use cases — where Bubble still wins
Let's be honest. Bubble has not lost every battle.
- Ultra-fast MVP (48-72h) for a prototype
- Simple multi-tenant site
- Agencies billing by the hour
- Landing pages with dynamic data
Example: an SME that wants a marketplace to test an offer — Bubble can deliver it in 6-8 weeks.
Trap #1: the low-code illusion
Trap #2: the cost of scaling
| Platform | Pricing | What it means |
|---|---|---|
| Bubble | Starter $25 · Pro $99 · Business $349 · Enterprise $1,299+/mo | ⚠️ Tier jumps forced by the architecture |
| Lovable | €150/mo workspace + €50-150/mo hosting = €200-300/mo | ✅ From 1 to 100k users, predictable costs |
Trap #3: architectural resilience
Trap #4: migration is a nightmare
Quick summary — when to choose what
| Situation | Tool |
|---|---|
| In a hurry (2-3 months max) | Bubble |
| 12-24 months of product ahead | Lovable |
| Scaling beyond 1,000 users | Lovable |
| You have a dev team | Lovable |
| Very tight year-one budget | Bubble |
| Architectural flexibility matters | Lovable |
Real case
- Fintech startup, 6 months on BubbleStarted on Bubble to test the market.
- 3,000 usersLimitations became obvious.
- Migration to Lovable8 weeks of work.
- Cost€50k of engineering.
- LessonBubble = good POC, poor long-term product.
