| Billing Architecture | usage based | hybrid |
| Developer Free Tier | ✓ Yes 1 hour of browser runtime / mo | ✓ Yes 500MB database storage (2 free projects) |
| Entry Paid Tier (Monthly) | $20 USD / mo | $25 USD / mo |
| Pricing & Cost Architecture | Developer free tier includes 1 hour of browser runtime per month. Standard paid plan is $20/mo for 20 browser hours ($1.00/hour), with auto-scaling concurrency. | 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. |
| Key Engineering Insight | Operates an enterprise-grade disposable browser fleet that circumvents bot protection by generating realistic human-like mouse trajectories and genuine TLS fingerprint handshakes. | Allows developers to store relational application state, user authentication (Row Level Security), and high-dimensional vector embeddings inside a single ACID-compliant Postgres database. |
Strengths & Trade-Offs
Objective engineering evaluation of both platforms
Browserbase Evaluation
Key Advantages
- ✓ Dedicated cloud-hosted headless Chrome fleet with persistent session cookies and residential IP proxy routing
- ✓ Advanced fingerprint randomization specifically designed to bypass Cloudflare Turnstile, DataDome, and bot challenges
- ✓ Live interactive remote inspector allowing developers and agent operators to visually debug browser sessions in real time
Limitations & Trade-Offs
- ✕ Proprietary cloud infrastructure with no self-hosted on-premise container edition available
- ✕ Significantly higher cost per operational hour compared to headless HTTP scrapers for static pages
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
