Most popular Heroku alternative. Teams switch for free tier (Render has one, Heroku doesn't), similar simplicity, and active development. Gain: free static sites, preview environments, managed databases included. Trade-off: fewer add-ons, smaller ecosystem.

Developers switch for modern DX and free tier. Gain: usage-based pricing, fast deployments, monorepo support, active feature development. Trade-off: newer platform, smaller community, some features still maturing.

Teams switch for global edge deployment. Gain: deploy close to users worldwide, Docker-native, generous free tier. Trade-off: steeper learning curve, Postgres has had issues, smaller support team.

Teams switch for buildpack compatibility and pricing. Gain: familiar workflow, managed databases, predictable costs, strong documentation. Trade-off: less polished than Heroku, fewer add-on integrations.

Frontend teams switch for Next.js/React optimization. Gain: zero-config frontend deployment, excellent DX, generous free tier for static sites. Trade-off: limited backend support, expensive at scale.

Teams switch for backend-as-a-service with predictable pricing. Gain: Parse-compatible, AI agent support, free tier available. Trade-off: different paradigm from PaaS, less flexibility for custom backends.
