Anomalo (site) monitors your data and flags anomalies and quality issues automatically, so teams find out about problems before stakeholders do. It's freemium with a free tier ("Start for Free"), but paid plan pricing is not stated on its site.

Telmai
Telmai (site) monitors customer data quality in real time, similar territory to Anomalo. It suits data teams who need continuous quality checks rather than one-off audits. Pricing is not disclosed on the site; you book a demo or product tour to learn more. Limitation: with no published pricing or free tier, evaluating cost upfront requires a sales conversation.
Cito
Cito (site) is built for data engineers who already run dbt tests but need something for patterns that change over time, plus incident-style debugging. It suits teams that want a "Datadog meets Incident.io" workflow for data issues. Pricing is not stated. Limitation: no free tier is listed, so trying it likely means contacting the team directly first.
ANODOT
ANODOT (site) is a real-time analytics and automated anomaly detection system aimed at enterprise use cases, with the longest track record here (launched 2017). It suits larger organizations needing broad, scalable anomaly detection across metrics. No pricing information is published; it appears to be a contact-sales, enterprise platform. Limitation: no free tier, so smaller teams or solo users have no low-cost way to test it.
ThresholdIQ Automated Detection Engine
ThresholdIQ (site) runs anomaly detection with a 100% client-side architecture, meaning data never leaves your browser. It suits privacy-conscious teams or those with data residency concerns. It offers a 7-day unlimited free trial, no card required; paid pricing isn't listed. Limitation: as a newer, smaller launch (2 votes), it has less track record than the enterprise options here.
Treeo
Treeo (site) watches your data continuously and reports what changed, using AI. It suits teams that prefer non-subscription pricing: either a fixed "Build and Own" project price agreed upfront, or "Build and Run" with a setup fee plus per-unit charges (per entity/month, per match). There's no free tier. Limitation: without published rate cards, you need to negotiate pricing directly before knowing your cost.
Erao
Erao (site) lets you analyze data without writing code or SQL, which is a broader analytics tool rather than a dedicated anomaly-monitoring product. It suits users who want to explore data themselves rather than get automated alerts. Pricing is not stated anywhere on its page. Limitation: it's not a direct anomaly-detection replacement for Anomalo unless paired with manual review.
StreamSense
StreamSense (site) brings real-time anomaly detection into VS Code, aimed squarely at developers rather than data or analytics teams. It suits engineers who want alerts inside their editor without switching tools. The homepage states it's free, though no pricing page details paid tiers. Limitation: it's a very early, low-traction launch (0 launch-day votes), so maturity and support are unproven.
How to choose
If you want the closest match to Anomalo's automated, always-on monitoring, start with Telmai or Cito. If data privacy or client-side processing matters, try ThresholdIQ's free trial. If you'd rather pay a fixed project fee than a subscription, look at Treeo. For enterprise scale, ANODOT is the established option; for a dev-focused, editor-native tool, consider StreamSense; for general no-code data exploration rather than dedicated anomaly alerts, Erao is the fit.
