Pricing

Free to start. Cheap to scale. Yours to run.

One lookup or a million, the response is the same one we'd want ourselves: the vendor, the reasoning, and nothing held back for a higher tier.

Early access: every request needs a free API key (auto-created when you sign up). Requests/minute and monthly lookup limits below are enforced for every plan; Growth and Scale get a 20% overage grace before pausing. See the docs for how to send your key.

Self-hosted

Don't want MAC addresses leaving your network? Run it yourself.

The API and the IEEE sync engine, the two binaries behind every lookup, are licensed for your own infrastructure. Install them and every lookup stays there: no third-party API in the request path, no per-query billing, no rate limits but your own hardware's. The public website stays ours to run; this license is for teams building their own tooling on top of the API.

  • Unlimited local queries
  • Installable via .deb package
  • Scheduled IEEE registry updates, same sync engine we run
  • Fits air-gapped and compliance-sensitive environments

Starting at $999/year per deployment. Built for network access control, IoT fleet management, and MDM vendors who need this at the core of their product. Not sure it's worth it yet? See what you're actually buying.

Live, not stale

Synced from source, not snapshotted once

Our sync service pulls IEEE's own registries on a recurring schedule. A lot of lookup tools ship a database someone downloaded once, years ago, and never touched again.

Free means free

No paywall on the depth

Randomization confidence, IEEE 802c classification, EUI-64/IPv6 derivation: every plan gets the full response. Paid tiers buy volume, not features.

Your call

Hosted or self-hosted, same engine

The API you'd call over HTTPS is the same binary you can run on your own servers. Start hosted, move to self-hosted later, or skip straight there.
