The web changes constantly.
You'll know first.

What you get

Precision monitoring, no fluff

Continuous monitoring
Nythra checks your URLs on a schedule you control — every minute, five minutes, or hourly. No gaps, no missed changes.
Real-time
AI diff summaries
Not just "something changed." Nythra reads the diff and tells you what shifted, why it might matter, and what was removed or added.
Powered by GPT-4o
Email + webhook alerts
Get notified by email with a plain-English summary, or fire a webhook into Slack, Zapier, or your own pipeline. Instant delivery.
Multi-channel
Full change history
Every change is logged with a before/after diff and timestamp. Browse months of changes. Export for audits or reports.
Versioning
API-first
Manage monitors, query change logs, and trigger checks programmatically. Nythra fits into your stack — not the other way around.
Developer
2-minute setup
Paste a URL. Set an interval. Done. No config files, no integrations, no agents to deploy. First alert in under 2 minutes.

"Nythra caught a pricing change on our competitor's page before our sales team even knew it happened. That intel was worth 10x the subscription cost."
Sarah Chen Head of Growth, Brightside
"We monitor our job listings, help docs, and legal pages. Nythra alerted us to an accidental rollback within minutes — before any customers noticed."
Marcus Webb CTO, Cascade
"The AI diff summaries are genuinely useful. I don't get a raw HTML blob — I get a plain-English explanation of what changed and why it matters."
Priya Nair Product Manager, Dataview
