incident.io is a hosted incident-management platform, priced mainly per seat, with Slack workflows and AI-assisted investigations. The alternatives below take two different paths: FireHydrant and PagerDuty cover incident response, while Grafana, Prometheus, Zabbix and New Relic focus on monitoring and telemetry. That distinction matters when you replace it: monitoring can feed an incident process, but it does not automatically replace response workflows. Compare the API surface, operating costs and hosting model against the parts of incident.io your team actually uses.
01Why people leave incident.io
AI still needs human review
Reddit users describe AI notes and summaries as useful drafts, but say responders still need to refine them and validate the underlying causes.
Setup takes engineering time
One incident.io user said a team member was mostly dedicated to setup, a cost to consider alongside per-seat pricing.
You want more control
Teams seeking open-source software or self-hosting may prefer Prometheus or Zabbix, which trade hosted convenience for control over their monitoring stack.
02The alternatives, ranked by fit
- API-first incident workflows
FireHydrantFireHydrantFireHydrant is the closest fit if you want to replace incident workflows rather than assemble them from monitoring tools. Its listed 350+ API endpoints make it the strongest option here for teams evaluating API coverage. Pricing starts at $25 with a free plan; check plan details and production limits before moving workflows or automations.
Trade-off: Pricing and production limits need close review before rollout.

$25/mofree plan - Open-source metrics
PrometheusPrometheusPrometheus is an open-source, self-hostable metrics system with PromQL and local metric storage. It costs $0 on the listed free plan, but your team runs the servers. Pick it to own metric collection and querying, not as a direct replacement for incident coordination; you will need to retain or build a separate response process.
Trade-off: You run the servers; incident workflows are not its focus.

Freefree plan - Self-hosted monitoring
ZabbixZabbixZabbix is an open-source, self-hostable monitoring option for teams that want to avoid per-device license fees. The free plan keeps software pricing at $0, while setup and tuning become your responsibility. It can replace part of an incident.io-adjacent monitoring stack, but teams must account for the separate work of coordinating responders.
Trade-off: Hands-on setup and tuning replace hosted convenience.

Freefree plan - Telemetry dashboards
GrafanaGrafanaGrafana suits teams consolidating telemetry, especially those using OpenTelemetry or Prometheus. It is open source and lists a free plan, with paid pricing from $19. This is a monitoring-platform choice, not a like-for-like incident workflow swap. Model telemetry use in your cost review: bills can grow with usage.
Trade-off: Telemetry costs can grow; incident coordination is a separate concern.
7.6/10from
$19/mofree plan - Broad response coverage
PagerDutyPagerDutyPagerDuty is a direct alternative for teams standardizing incident response, with on-call response, automation and broad integrations. Pricing starts at $21 with a free plan. Compare plan pricing against your expected users and features before migrating, since the platform's pricing needs close review. It is a hosted option, not an open-source route.
Trade-off: Review platform pricing closely as users and features grow.
6.8/10from
$21/mofree plan - Observability with response
New RelicNew RelicNew Relic is a hosted observability platform that includes incident response across application and infrastructure. Pricing starts at $10 with a free plan, and the free ingest allowance may suit teams starting out. Check ingest and user costs as usage scales. Choose it to consolidate observability, not for self-hosting or open-source control.
Trade-off: Ingest and user costs can rise with usage.

Questions people ask
Which incident.io alternative is open source?
Prometheus, Grafana and Zabbix are listed as open source. Prometheus and Zabbix are also self-hostable. Prometheus focuses on metrics and PromQL; Zabbix is infrastructure monitoring; Grafana covers dashboards and telemetry. None should be treated as a drop-in replacement for incident coordination without checking your workflow requirements.
What is the cheapest incident.io alternative?
Prometheus and Zabbix list free plans at $0, but you operate the software yourself; Zabbix also requires setup and tuning. Among the listed hosted options, New Relic starts at $10, Grafana at $19, and PagerDuty at $21, each with a free plan. Compare usage and feature limits, not just starting prices.
Which alternative has the largest stated API surface?
FireHydrant lists 350+ API endpoints, making it the clearest choice in this group for teams comparing published API coverage. Check which endpoints are available on the plan you need, along with production limits, before migrating integrations. The endpoint count alone does not establish whether its API covers your incident.io workflows.
