Moving from Zenduty to Oppex: from faster response to resolution

Zenduty is a solid alerting and on-call tool, and it promises up to 60% faster MTTR. (It is now sold as Xurrent IMR.) Oppex is built for the goal beyond that: every incident resolved in under 10 minutes.

The difference is where the AI stops. A suggestion still leaves an engineer to check it and act on it. Oppex brings the evidence, proposes the fix, and runs it once your engineer approves.

Zenduty helps you respond. Oppex helps you resolve.

Four things that change

From suggestions to evidence. A root-cause suggestion still leaves your engineer opening dashboards to check it before anyone acts. Oppex Nova shows the evidence behind every finding — the deploy, the error, the matching past incident — and a confidence level, so the check takes seconds.

From manual fixes to one approval. Once the cause is known, someone still runs the rollback or the runbook by hand, often at 2 a.m. With Oppex you approve the fix in Slack and Oppex runs it, or automated runbooks act where your policy allows. One approval instead of a checklist.

From plan limits to no caps. Zenduty Growth stops at 50 users, 5 teams and 5 integrations per team; beyond that you need a custom Enterprise quote. Oppex Business has no caps on users, teams or integrations, with one published price per user.

From hand-written updates to automatic ones. Stakeholder updates still depend on someone writing them mid-incident. Oppex sends executives plain-language updates automatically: what is affected, who owns it, and when the next update arrives.

Your engineers stay in control throughout. Low-confidence findings are labelled as such, nothing runs automatically on a guess, and a wrong finding can be marked so Oppex learns from the correction.

What it costs

Zenduty (Xurrent IMR) prices and limits from its public pricing page, October 2026. See the full Oppex vs. Zenduty comparison and Oppex pricing.

The real saving is time. Oppex customers report 5× faster MTTR and 50% less on-call effort. For a 20-person team, a few hours saved per engineer each month is worth far more than the difference in licence price.

How to switch without the risk

1. Week 0 — free noise audit. Send one week of alerts; we show you your noisiest services and agree a success target, for example 50% fewer pages and MTTR halved.
2. Week 1 — shadow mode. Zenduty keeps paging as normal. Oppex receives a copy of every alert, groups and investigates it, and pages nobody.
3. Weeks 2–3 — side by side. Oppex pages for your pilot services, with Zenduty still on as a backup.
4. Week 4 — your decision. We review pages, noise, MTTA, MTTR and hours saved against the target. If we miss it, you keep Zenduty exactly as it was.
5. After week 4 — migration complete. Oppex becomes your primary incident management platform.

Our team imports your users, teams, services, on-call schedules and escalation policies from Zenduty, and builds any integration you need that is not there yet.

"Oppex has been easy to adopt, simple to get started with, and straightforward to integrate with our existing systems. It also gives us a lot of flexibility in managing on-call operations." — Umapathy Manohar, Principal Architect, Hector AI
