| Developer Free Tier | ✓ Yes 500MB database storage (2 free projects) | ✓ Yes 100% Free MIT Runtime + Free Edge Tier |
| Entry Paid Tier (Monthly) | $25 USD / mo | $10 USD / mo |
| Pricing & Cost Architecture | Free tier offers 2 managed projects with 500MB database storage (~250k vectors). Pro plan starts at $25/mo with 8GB storage and scalable compute add-ons. | Open-source Wasmer runtime is 100% free (MIT license) for self-hosting. Wasmer Edge cloud includes a generous free tier (100k requests/mo) and Pro plans starting at $10/mo. |
| Key Engineering Insight | Allows developers to store relational application state, user authentication (Row Level Security), and high-dimensional vector embeddings inside a single ACID-compliant Postgres database. | Implements WASIX (an extended POSIX standard for WebAssembly), enabling full multi-threaded Python, C, and Rust binaries to run inside cryptographically isolated Wasm sandboxes with 0.1ms startup. |
Strengths & Trade-Offs
Objective engineering evaluation of both platforms
Supabase Vector Evaluation
Key Advantages
- ✓ Combines vector search with full Postgres ecosystem: Row Level Security, ACID transactions, and relational joins
- ✓ Instant auto-generated client APIs (REST, GraphQL, real-time WebSockets) with zero backend boilerplate
- ✓ Permissive open-source stack with official Docker compose deployment for self-hosting on any VPS
Limitations & Trade-Offs
- ✕ Free tier projects pause automatically after 7 days of inactivity (resumed upon dashboard login)
- ✕ Dedicated standalone C++ vector stores can achieve higher raw QPS for multi-million vector datasets
Wasmer Evaluation
Key Advantages
- ✓ Sub-millisecond cold starts (0.1ms): orders of magnitude faster than Linux containers and microVMs
- ✓ Cryptographically isolated sandboxing with zero access to the host filesystem unless explicitly bridged
- ✓ WASIX support allows running complex POSIX multi-threaded applications (including Python and bash) in Wasm
Limitations & Trade-Offs
- ✕ Compiling arbitrary complex native C extensions or dynamic shared libraries to Wasm can require custom toolchains
- ✕ Not designed for running full graphic environments or standard Docker daemon workflows
