Comparison
ChainScreen alternative for teams that need alerts, not just screening
ChainScreen and OFAC Alert both sit around $99/mo, but they solve different halves of the same problem. Screeninganswers “is this address sanctioned right now?” — a check you run. Monitoringanswers “tell me the instant it changes” — a push you subscribe to. If what you need is the second one, here's how OFAC Alert compares.

Where OFAC Alert wins
OFAC Alert is built monitoring-first. You subscribe to the exact (chain, address) pairs or programs you care about, and the moment Treasury adds or removes one, you get a signed change alert pushed to your webhook, email, or Telegram — with delivery retries and a transparent freshness record. For developers, there's a clean REST API with batch screening and a recent-events stream.
When ChainScreen might be the better fit
We'd rather you pick the right tool than the wrong subscription. If your priority today is a broad, multi-list screening UI with a built-in case/audit workflow — and you don't need programmatic push alerts — a dedicated screening product like ChainScreen may suit you better. OFAC Alert is the sharper choice when you need to know the instant something changes on the addresses you watch, delivered into your own systems.
