Both platforms let you build apps with AI, but they differ in important ways.
Key differences
Backend
Maris AI includes Express + MongoDB backend automatically. Bolt.new generates frontend only — you need to set up your own backend.
Pricing model
Maris AI uses credits that never expire. Bolt.new charges a monthly subscription — unused credits are lost.
Cost per app
Maris AI: €0.11-0.13 per credit, apps cost 3-10 credits. Bolt.new: $20/month subscription regardless of usage.
Code ownership
Both let you export code. Maris AI exports to GitHub with one click.
AI agents
Maris AI uses 11 specialized agents (Researcher, Architect, Designer, Frontend, Backend, API Integrator, QA, Testing, PM, Image, Visual Evaluator). Bolt.new uses a single AI model.
