Pricing

The provenance layer your
knowledge stack is missing

Run locally for free, or use the managed API. Either way, you only pay for what you use. No base fee, no seat licenses.

Self-Serve
Free
Install locally and run on your own hardware. Same Rust engine, same API, no limits. Like SQLite — it's just a file.

Attest fits into your existing stack

Attest is the provenance and verification layer. It enriches the tools you already use — not a replacement for any of them.

Neo4j
Graph queries + traversal
Pinecone / Weaviate
Vector search + RAG
Postgres / DuckDB
Relational + analytics

Frequently asked questions

How is Attest different from a graph database?
Graph databases store relationships. Attest stores claims about relationships — with provenance, confidence scores, source tracking, and contradiction detection. You can use both together: Attest verifies and scores claims, then you export high-confidence edges into Neo4j, Postgres, or whatever your app queries.
Is the self-serve library really free?
Yes. pip install attestdb gives you the full Rust engine, 24 REST endpoints, the audit chain, all 12 connectors, and snapshot/restore. It runs on your laptop, your server, or in a container. No account, no license key, no telemetry.
What happens if I stop using the managed API?
Cancel anytime via the Stripe billing portal. You keep read-only access for 30 days, then your data is archived to S3 cold storage. You can export your data at any point during the grace period.
How is storage measured?
Your .attest database file size, measured daily. The Rust engine's binary format is compact: 1 million claims typically use under 500 MB. Sidecars (audit chain, tokens) are included in the measurement.
Can I migrate between self-serve and managed?
Yes. Export your .attest file with db.snapshot() and import it on the managed API, or vice versa. Same file format, same engine.
Do you offer volume discounts?
Not yet. Contact hello@attestdb.com for custom terms if your workload exceeds 10M claims/month or you need a dedicated instance.
