| Billing Architecture | usage based | free |
| Developer Free Tier | ✓ Yes 500 scrape credits / mo | ✓ Yes 100% Free (PostgreSQL license) |
| Entry Paid Tier (Monthly) | $16 USD / mo | Free / Custom |
| Pricing & Cost Architecture | Monthly credit quota: Free tier provides 500 scrape credits/mo (1 page = 1 credit; 1 crawl = 1 credit per discovered page). Starter plan is $16/mo for 3,000 credits ($0.0053/page). Growth is $99/mo for 100,000 credits. | 100% Free and open-source under the PostgreSQL License. Pre-installed and available with zero license fees on Supabase, AWS RDS, Neon, Azure, and self-hosted Postgres. |
| Key Engineering Insight | Created after developers struggled with fragile Puppeteer scripts for RAG; its scraping cluster processes millions of web pages weekly with automated proxy rotation and stealth headers. | Changed the vector landscape by demonstrating that 90% of RAG architectures do not need a standalone vector database; they can simply execute vector queries on their existing Postgres tables. |
Strengths & Trade-Offs
Objective engineering evaluation of both platforms
Firecrawl Evaluation
Key Advantages
- ✓ Converts complex JavaScript-rendered SPAs and shadow DOM into clean, structured markdown optimized for LLM tokenization
- ✓ Includes built-in automated anti-bot bypass, residential IP rotation, and captcha handling with no external proxy configuration
- ✓ Official Model Context Protocol (MCP) server support and official SDKs for Python and TypeScript
Limitations & Trade-Offs
- ✕ AGPL-3.0 copyleft license requires open-sourcing modifications when self-hosting in proprietary environments
- ✕ Credit consumption scales rapidly on deep recursive crawls across multi-page domains
pgvector Evaluation
Key Advantages
- ✓ Runs directly inside PostgreSQL: eliminates data synchronization pipelines, extra microservices, and network hops
- ✓ Full ACID compliance, transactional integrity, relational SQL joins, and row-level security on vector tables
- ✓ Supports exact flat search, approximate IVF-flat, and HNSW graph-based similarity indexes
Limitations & Trade-Offs
- ✕ HNSW index build times and memory usage on Postgres can be slower than specialized standalone C++/Rust engines
- ✕ Lacks out-of-the-box multimodal vectorization wrappers or automatic reranking pipelines found in dedicated vector DBs
