Alerts + Paging Vendor Comparison

Status: research-only. This document does NOT constitute legal or tax advice. Before signing any annual contract or enterprise agreement, consult a CPA about the deductibility and timing of SaaS commitments. Before any data-processing agreement with a non-US vendor, consult an attorney licensed in relevant jurisdictions. Last updated: 2026-06-10. Sources as of that date — verify freshness.

TL;DR

PagerDuty's free tier is legitimately usable for a single operator (5-user cap, 100 SMS/phone/mo), but lacks maintenance windows and phone escalation on free. Better Stack is the strongest all-in-one value at $29/mo for one responder: unlimited phone/SMS, uptime monitoring, heartbeats, status page, and log ingestion included. Opsgenie is end-of-sale and cannot be used by new accounts. The "stay with Sentry alerts only" option loses on-call scheduling, phone escalation, and maintenance windows — the specific gaps that matter for a solo operator.

Opsgenie — Disqualified

Atlassian closed new Opsgenie sales on June 4, 2025. New accounts cannot be created. Existing customers run until April 5, 2027. This vendor is not a viable option for Raxx.

Facts (with citations)

PagerDuty

• Free tier: up to 5 users, 1 on-call schedule, 1 escalation policy, 750+ integrations, push + email + SMS/phone (100/month international), API access. No maintenance windows on free.
• Professional: $21/user/month (annual) / $25/user/month (monthly). Unlimited notifications, advanced ITSM integrations, maintenance windows.
• Business: $41/user/month (annual). Custom fields, workflow automation, 3 custom incident types.
• No per-incident charges — purely per-user billing.
• Native Sentry integration (webhook-based): Sentry alert rules trigger PagerDuty incidents with severity mapping. Source: https://sentry.io/integrations/pagerduty/
• Heroku integration: Sentry's Heroku integration is deprecated as of October 28, 2025 — deploy tracking via webhook only going forward. Source: https://sentry.io/integrations/heroku/
• 650+ integrations including GitHub, Cloudflare (via webhook), Slack.
• Switching cost: high. PD uses proprietary incident routing DSL; escalation policies, schedules, and service configs are not portable YAML.

Better Stack

• Free tier: 10 monitors + 10 heartbeats, 1 status page, Slack/email alerts, 100k exceptions/mo, 3 GB logs (3-day retention), push notifications. No phone/SMS on free.
• Responder (paid): $34/month or $29/month (annual). Includes unlimited phone call alerts, unlimited SMS, unlimited push, on-call scheduling with escalation, advanced Slack/Teams workflows, incident management.
• Team members (telemetry access only, no paging): $0/month.
• Additional monitors: $25/month per 50 monitors ($21/yr).
• Additional heartbeats: $20/month per 10 ($17/yr).
• Log management: 3 GB/3-day retention free; paid bundles from ~$0.15/GB ingestion.
• Status pages: 1 included; additional at $15/month.
• SSO (Azure/Okta): $5/user/month extra.
• All-in-one: uptime monitoring + heartbeats + on-call paging + log ingestion on a single platform.
• Switching cost: low. Checks and alert routes exportable; S3/webhook drains are standard.

Grafana OnCall (Cloud)

• Free tier: 3 users, full feature access including OnCall scheduling.
• Pro: $20/active IRM user/month. Active = included in OnCall schedule or performing incident actions.
• OSS version: archived March 24, 2026 — self-hosted Grafana OnCall OSS is no longer viable.
• Push notification relay for OSS also deprecated March 24, 2026.
• Best fit if you are already running Grafana Cloud for observability (dashboards + Prometheus/Loki). Otherwise the IRM feature alone is underweight for the price.
• Sentry integration: available via webhook.
• Switching cost: low for data; medium for alerting rules if heavily invested in Grafana dashboards.

Splunk On-Call (VictorOps)

• Starting price: ~$9/user/month (unsourced from primary — confirm with https://www.splunk.com/en_us/products/pricing.html).
• Cisco acquired Splunk in 2024; pricing and roadmap continuity uncertain.
• Enterprise-tier feel: war rooms, SSO, full-stack analytics. Significant overhead for 1-user operation.
• Best fit: organizations already on Splunk SIEM/ITSI. Not appropriate for pre-launch single-operator SaaS.
• Switching cost: high — deeply coupled to Splunk ecosystem.

ilert

• Free tier: up to 5 users, 100 SMS/voice notifications account-wide per month, 1 on-call schedule, 1 escalation policy, 1 status page. All inbound integrations (alert sources) available on all plans including Free.

• ITSM integrations (ServiceNow, Jira) require Scale+.
• Webhook subscriptions for status page: Scale and Enterprise only.
• European company (Germany-based) — GDPR-native data processing agreement available.
• Minimum 3 users on paid plans makes pricing less attractive for truly single-operator use.
• Switching cost: low — webhook-based integrations, no proprietary lock-in at the config layer.

• Switching cost: low — webhook-in / webhook-out architecture.

Sentry-Alerts-Only (No Additional Paging Tool)

What you have today: Sentry issue alerts → email + Slack notification rules. You can add PagerDuty or others as a Sentry integration.

What you LOSE by staying Sentry-only: - No phone/voice call paging (Sentry does not make phone calls) - No on-call scheduling (Sentry has no concept of "who is on-call right now") - No escalation policy (alert fires once; no retry-to-backup path) - No maintenance windows (Sentry can suppress alerts per-project but not time-window globally) - No heartbeat / cron-job monitoring - No independent status page (Sentry's status page is for Sentry itself, not your app) - No runbook annotation on alerts

What you KEEP: - Error grouping + stack traces - Release tracking + regression detection - Performance tracing (if Sentry Performance enabled) - Zero additional monthly cost

Verdict: Sentry-only is adequate for a developer at a laptop; not adequate for an operator who needs to be woken up at 3 AM if production is down.

Options Compared (Matrix)

Jurisdiction Flags

• ilert is Germany-based — data processing agreement is GDPR-compliant by design. For EU customers, this is a minor plus. For US-only operation, no material difference.
• PagerDuty and Better Stack are US-based entities. Standard DPA available for GDPR compliance.
• Spike.sh: jurisdiction not confirmed from public sources — verify before adding to DPA stack if EU expansion is planned.
• None of these vendors trigger CCPA as data processors on your behalf (they process operations data, not end-user personal data).

Timing / Deadlines

• Opsgenie existing customers: service ends April 5, 2027. If Raxx were already a customer, migration would be required before that date. Not applicable here.
• Grafana OnCall OSS: already archived as of March 24, 2026. Self-hosted path is closed.
• PagerDuty free plan: no time limit — usable indefinitely for pre-launch.
• Annual contracts (Better Stack $29/mo paid annually = $348/yr): locking in at signing. Verify cancellation/refund terms before committing.

Recommended Path — v1 (Pre-Launch)

Better Stack Responder at $29/month (annual) = $348/year is the strongest single-tool choice for a solo operator. It replaces three separate tools (uptime monitor, on-call pager, heartbeat/cron monitor) with one subscription, includes unlimited phone + SMS paging, and adds 3 GB log ingestion as a bonus. The free tier is a legitimate evaluation path before committing.

If cost is a hard constraint and you want $0 at launch: PagerDuty Free works for the paging function but requires a separate uptime monitor and gives only 100 SMS/phone calls per month. That cap becomes a problem if alert noise is high.

Recommended Path — v2 (Post-Launch / First 100 Customers)

Once you have a team (even 2-3 people), the on-call scheduling rotation and escalation policies matter. Better Stack scales cleanly — each additional responder is $29/month. If you are by then running Grafana Cloud for metrics (Prometheus/Loki), Grafana OnCall at $20/active-IRM-user/month makes sense to consolidate. PagerDuty Business becomes relevant only if you need deep ITSM integrations (ServiceNow, Jira Service Management).

Questions for Your CPA

1. Better Stack at $29/month (annual) = $348/year — is this deductible as a software/SaaS business expense in the year billed or the year covering the service period?
2. If you sign a multi-year or pre-paid contract (PagerDuty Business or Splunk On-Call enterprise), how does the prepayment timing affect deductibility for an LLC taxed as a pass-through?
3. Are there any Pennsylvania state tax implications for SaaS subscription expenses that differ from federal treatment?
