AI overview
Spike.sh is cheaper for a two or three person team, and it does alerting, on-call and escalations well. Its incident workflow is thin, though. Pagerly adds incident channels, roles, a timeline, an AI SRE agent and AI post-mortems inside Slack, and bills per team, so the cost stays flat as more engineers join the rotation.

What would Spike.sh cost your team?
Spike.sh lists at about $9/user/month, per seat. Pagerly is $39 per team plus $4 per user for paging - same workflows, inside Slack.
That's not a discount - that's how much extra teams pay for the same workflows. Pagerly's side uses published pricing: $39 per team per month on Starter, plus $4 per user per month for paging by call. Spike.sh's paid plan is listed at roughly $9 per user per month, so the figure here is approximate and worth verifying on spike.sh. On price alone it wins for two or three people, where Pagerly is not always cheaper. Pagerly's side uses Starter at $39 per team plus $4 per user for phone paging, which pulls ahead as the rotation grows.
Why teams look beyond Spike.sh
Spike.sh does a lot for little money. You get schedules, escalations, phone and SMS paging, status pages and a long list of integrations, with a free tier and a paid plan around $9 per user. For a small team that mainly wants to be woken up reliably, that is hard to beat.
The gap appears once an alert becomes an incident. Spike.sh is alert-first: it tells the right person something broke. Running the incident itself, with a channel, roles, updates and a write-up, mostly happens somewhere else or by hand.
What teams hit with Spike.sh
- The incident workflow is thin. Alerts reach Slack, but opening a channel, assigning a commander and keeping a timeline are still manual steps.
@oncallstays manual. Nothing keeps a Slack user group pointed at the current responder, so someone edits it every handover.- Post-mortems start from a blank page. There is no AI investigation or draft to work from after the fact.
- Tickets live in another tab. Follow-ups in Jira, Linear or Asana are not synced back to the incident.
- Per-user pricing grows with the rotation. The bill is small at five people and noticeably larger at thirty.
How to move from Spike.sh to Pagerly
- Add Pagerly to Slack. One OAuth click; there is no console to set up.
- Recreate your rotations. Pagerly imports PagerDuty and Opsgenie schedules, not Spike.sh, but a rotation takes a few minutes to build in Slack.
- Point alert sources at Pagerly. Datadog, Grafana, Sentry and CloudWatch connect through webhooks or native integrations. Move them one at a time and keep Spike.sh running in parallel.
- Turn on paging. Phone and SMS paging is a per-user add-on; enable it for the people who carry the pager.
- Turn on
@oncallsync, then retire Spike.sh. Once alerts flow and the group updates itself, there is nothing left for it to do.
When Spike.sh is the better choice
Be honest about the fit:
- You are two or three people. At that size a $9 per-user plan or the free tier is cheaper than a $39 team plan plus paging.
- You only need alerting. If schedules, escalations and phone calls are the whole requirement, a focused tool is enough.
- You want the lowest absolute price. Pagerly is flat and predictable, not the cheapest option at every size.
For a Slack-first team that runs real incidents, none of those usually hold for long.
Which should you choose?
| If you are… | Choose |
|---|---|
| A two or three person team that only needs alerts | Spike.sh |
| A Slack-first team running real incidents | Pagerly - channels, roles and AI post-mortems in Slack |
Tired of editing the @oncall group by hand |
Pagerly - synced on every handover |
| Growing headcount and a growing per-seat bill | Pagerly - flat per team, unlimited users |
| Managing on-call as code | Pagerly - REST API, MCP server and Terraform |
Frequently asked questions
Is Spike.sh cheaper than Pagerly?
For two or three people, often yes, especially on its free tier. Around 10 engineers the two are close, and at 30 engineers Pagerly on Starter with paging for everyone is about $159 a month against roughly $270. Spike.sh pricing is approximate here, so check spike.sh.
Why not just stay on Spike.sh?
If you only need alerts, schedules and escalations, staying is a sound choice. Teams move when they want incident channels, roles, a timeline, AI investigation and post-mortems in Slack instead of stitching those together by hand.
Does Pagerly keep a Slack @oncall group updated?
Yes. Pagerly updates the Slack user group on every handover, so mentioning @oncall always reaches the current responder. Spike.sh does not do this.
Can Pagerly page by phone and SMS like Spike.sh?
Yes. Phone and SMS paging is an optional $4 per user per month add-on, enabled for the people who carry the pager. Slack and push notifications work without it.
Can I import my Spike.sh schedules?
Pagerly imports from PagerDuty and Opsgenie, not Spike.sh. Rotations are quick to recreate in Slack, and you can run both tools side by side while you move alert sources over one at a time.
Does Pagerly charge per user?
No. Plans are flat per team, $19 per month on Basic and $39 on Starter, with unlimited users and incidents. Only optional phone and SMS paging is per user.
What do I get that Spike.sh lacks?
AI SRE investigations, AI post-mortems, Jira, Linear and Asana ticket sync, and a REST API, MCP server and Terraform provider for managing on-call as code.
