Crunchy Bridge and Rivestack are both flat-priced dedicated Postgres — the difference is focus. Rivestack ships with pgvector pre-installed and HNSW-tuned for production, EU-first data residency in Germany, and a product built for RAG and AI teams rather than general Postgres ops. First month free on Solo. Migration help is free.
Both are solid flat-priced dedicated Postgres. The gap is product focus.
Crunchy Bridge ships pgvector as an available extension — you enable it and tune it yourself. Rivestack ships with pgvector pre-installed and HNSW indexes tuned for production: ~1,000 QPS at recall@10 0.93 on 250k × 1536-dimension vectors on a $35 node, on local NVMe. For AI teams who want managed vector search in Postgres without the ops overhead, that difference shows up in day one latency, not after a week of tuning.
Managed pgvector →Rivestack runs in Falkenstein, Germany. EU data and backups never leave the EU, we are an EU company, and Data Processing Agreements are available on request. For EU AI startups building GDPR-compliant products on Postgres, compliance is a given — not a region dropdown to get right at project creation.
Managed PostgreSQL overview →Crunchy Bridge is excellent for DBA teams and enterprise Postgres — one of the most credible flat-price managed Postgres options in the market. Rivestack is narrower: dedicated pgvector hosting for small and mid AI teams who want managed RAG-ready Postgres without running infrastructure. Solo is $15/month flat, first month free. If you are evaluating Crunchy for an AI workload specifically, the product focus is the real difference.
PostgreSQL for AI →Two flat-priced dedicated Postgres hosts — same model, different focus.
| Rivestack | Crunchy Bridge | |
|---|---|---|
| Product focus | pgvector + RAG for AI teams | General-purpose managed Postgres |
| Compute model | Dedicated VM per database | Dedicated VM per database |
| Entry price | $0 shared / $15 dedicated (1st month free) | ~$10/mo smallest dedicated instance |
| Pricing model | Flat per node, no surprises | Flat per instance (genuinely comparable) |
| pgvector | Pre-installed + HNSW-tuned | Available extension, tuning on you |
| Embedding workflow | Managed auto-embed support for RAG | Not included |
| Data residency | EU by default (Germany) | Multiple regions, US-based company |
| DBA tooling & maturity | Lightweight — pgvector focus | Deep DBA tooling, more established |
| Scale ceiling (vectors) | ~1M × 1536d hot on Scale node | Standard Postgres limits |
| Best fit | Small/mid AI teams on dedicated pgvector | Enterprise/DBA-heavy Postgres workloads |
Crunchy Bridge is a well-regarded managed Postgres with strong DBA tooling and a lower entry price — it is not a bad choice. If your team is DBA-heavy or you need general-purpose enterprise Postgres, consider it seriously. Rivestack is the focused choice for AI and RAG teams who want pgvector ready to go in a GDPR-ready EU environment, without having to tune it.
Standard Postgres on both ends — usually a few hours, and we help, free.
Row counts, vector dimensions, and your current Crunchy Bridge plan. We reply within ~48 hours with a plan recommendation, expected QPS and latency, and a side-by-side cost comparison. Both platforms are flat-priced dedicated Postgres, so the comparison is usually straightforward. If Rivestack is not a better fit for your workload, we say so in the same reply.
Crunchy Bridge is standard Postgres, so pg_dump / pg_restore moves smaller databases in minutes. For always-on production we set up logical replication and cut over with under a minute of write downtime — your read traffic stays online throughout. Your pgvector indexes, schema, and queries move over unchanged.
Standard PostgreSQL over SSL on port 5432. Your driver, ORM, pgvector queries, and application code work unchanged. You get pre-tuned HNSW and EU data residency from the first query.

What AI teams ask when evaluating flat-price dedicated Postgres options.
Crunchy Bridge is a well-built managed Postgres and a genuine flat-priced competitor — one of the few honest alternatives in the market. The reasons teams look at Rivestack instead are usually focused: they want pgvector ready to go without manual tuning, they need EU data residency for GDPR compliance without thinking about it, or they are a small AI team who wants a product built for RAG workloads rather than a general Postgres platform. If any of those apply, Rivestack is worth comparing.
Crunchy is actually cheaper at the very entry tier — their smallest instance runs around $10/mo versus $15/mo for Rivestack Solo. Both are flat pricing with no usage metering, so neither has a billing surprise problem. The practical difference is that Rivestack Solo includes the first month free, and the pricing climb from entry to production is similar on both. For most AI teams the $5/mo entry gap is less significant than product focus and data residency.
Three things: pgvector ships pre-installed and HNSW-tuned — we measure ~1,000 QPS at recall@10 0.93 on 250k × 1536-dimension vectors on a $35 node, on local NVMe, without any tuning work on your end. EU-first data residency by default: all data and backups stay in Falkenstein, Germany unless you choose otherwise. And a managed embedding workflow for RAG teams who want auto-embed support in Postgres without building the pipeline themselves.
If you are running serious DBA workloads, need a more established platform, or Postgres is your core infrastructure rather than a vector store, Crunchy Bridge earns its reputation — they have strong Postgres pedigree and tooling. Similarly, if you need a very low-entry price and pgvector is not your primary concern, their ~$10/mo entry is cheaper. Rivestack is focused on small and mid AI teams specifically; if you are an enterprise DBA team, Crunchy is probably the better fit.
Both platforms are standard Postgres, so this is one of the simpler infrastructure migrations you can do. pg_dump / pg_restore handles most databases in minutes; for larger always-on systems we use logical replication and a sub-minute cutover. Your pgvector schema, indexes, and queries move unchanged. Migration help is free — email rescue@rivestack.io or see the Switch offer page and we will plan it with you.
Yes, and without any setup work. pgvector is pre-installed and tuned: HNSW indexes are built with production settings and we measure sub-4ms p50 latency at ~1,000 QPS recall@10 0.93 on 250k × 1536-dimension vectors. The Scale node (16 GB RAM) serves 1M × 1536d hot. Your existing pgvector schema, indexes, and queries move over unchanged from any standard Postgres host.
Your data is encrypted in transit and at rest, backed up daily to separate S3-compatible storage within the EU with point-in-time recovery, and HA clusters run Patroni-managed automatic failover. We are an EU company, so GDPR obligations are built-in rather than a compliance add-on. DPAs are available on request. And because it is vanilla PostgreSQL, you can pg_dump your entire database and leave at any moment — no lock-in.
Yes. The free tier gives you a Postgres database with pgvector in about a minute, no credit card. Load a sample of your vectors, run your real queries, and measure latency before you commit. Solo is the first month free if you want to run a production workload in parallel and compare directly.
