- Unified services: auth, storage, realtime, edge functions, vector search, and monitoring are all available under one roof.
- Open-source core with a self-hosting option for teams that need portability or compliance control.
- Developer velocity: automatically generated APIs and fast local-to-cloud iteration streamline the development workflow.
Standout Features
PostgreSQL Core
- Production-grade reliability, backups, and the ability to leverage the extensive PostgreSQL ecosystem.
Built-in Auth & RLS
- Ready-to-use authentication combined with row-level security policies for secure multi-tenant applications.
Realtime & Edge Functions
- Real-time data subscriptions and edge-deployed functions facilitate responsive user experiences.
Vector Support
- Integrated vector storage and similarity search, useful for AI-enabled applications.
Observability
- Built-in monitoring and logs help track performance and troubleshoot issues.
Pricing
| Plan | Cost | Key Details |
|---|---|---|

Pros
- Open-source & self-hostable – full control over data and compliance.
- PostgreSQL foundation – powerful SQL queries, extensions, and ecosystem compatibility.
- All-in-one stack – reduces the need to stitch together separate services for auth, storage, and realtime.
- Generous free tier – lets individuals and startups experiment without upfront cost.
- Vector integration – ready for LLM-driven features and AI workflows.
Cons
- Managed service pricing can become expensive for high-traffic or enterprise workloads.
- Feature parity with Firebase’s ecosystem may still be catching up in certain niche areas (e.g., advanced analytics).
- Learning curve for teams unfamiliar with PostgreSQL or RLS policies.
