Evenstamp runs as one compiled Rust binary with embedded SQLite and in-memory Polars. That footprint supports 85–94% gross margins while pricing 60%+ below incumbent list prices. Start free at 25,000 identifications; upgrade when the free cap actually binds.
Start free at 25,000 identifications. Scale without a platform fee. Move the entire engine into your own VPC when regulatory or residency requirements demand it.
Estimates use published overage rates. Annual billing discounts the base plan; overage remains usage-based. Taxes excluded.
Full cross-browser identification for side projects, staging, and proofs of concept.
Five times the volume of the incumbent entry tier at less than half the price.
The full wire-to-kinematics stack for fintech, e-commerce, and high-traffic platforms.
Run the entire Rust + Polars + SQLite + AF_PACKET engine inside your own VPC.
Cloud plans include first-party proxy routes, ECDH P-256 envelopes, single-use nonces, and 99.9% uptime. Sovereign includes a 99.99% SLA and deployment review.

| Tier | Target | Base price | Included / month | Overage | Core capabilities |
|---|---|---|---|---|---|
| Developer | Indie, POC, staging | $0 | 25,000 / month | Hard cap | BrowserID, fuzzy DeviceID, VM/headless checks, 7-day retention |
| Growth | Startups, SaaS | $39/mo · $31/mo annual | 100,000 / month | $0.80 / 10k | WASM steal-time, shader benchmarks, cross-realm checks, canvas traps, 30-day retention, webhooks |
| Scale | Fintech, e-commerce, high traffic | $199/mo · $159/mo annual | 1,000,000 / month | $0.50 / 10k | Polars biometrics, TCP TTL/MSS wire verification, WebGPU probes, CDP traps, first-party CNAME, 1-year retention |
| Sovereign | Regulated enterprise, crypto, iGaming | $999/mo billed annually | Unlimited (4 vCPU nodes) | $199/mo per extra node | Single-binary Rust + SQLite, AF_PACKET sniffer, zero telemetry egress, raw 8D vector export, 99.99% SLA |
Provider credentials stay in the Rust engine. The browser only receives a hosted checkout URL.
Airwallex
Hosted checkout in SUBSCRIPTION mode. The card is stored by Airwallex, renews automatically, and the engine receives a signed billing_checkout.completed webhook before activating the plan.
NOWPayments
Hosted invoice for one monthly or annual term. A confirmed payment extends the plan period; renewal is a fresh invoice, so there is no recurring crypto debit or stored wallet consent.
Fraud and security work is cross-functional. Per-seat pricing suppresses adoption and creates procurement friction, so every plan includes unlimited team access.
Predictable free-tier cost and a clean upgrade trigger. Hobby projects never receive a surprise overage bill; Growth removes the cap and bills overage per 10,000 identifications.
Growth and Scale use an Airwallex hosted billing checkout in subscription mode. After checkout, Airwallex creates the subscription and payment method, and a signed webhook activates the plan in the engine.
NOWPayments issues a hosted crypto invoice for one monthly or annual term. A confirmed payment extends the account period by that term. Renewal is a new invoice; there is no automatic crypto debit.
Enterprise procurement and deployment review require a committed relationship. Monthly self-serve Sovereign would be a support and compliance risk.
Scale overage applies. A custom committed-use contract is available with a volume discount and a dedicated support channel.
Start with the free developer tier, run the integration tests against the real engine, then decide whether the managed edge or the sovereign binary fits your architecture.
