If 15 of your 100 engineers handle incidents, Flashduty Professional costs $5,220 a year. PagerDuty Business costs $49,200 a year with 100 full seats. If the other 85 people use read-only Stakeholder licenses, PagerDuty drops to about $10,980 a year, but those 85 people can't be paged. The difference comes from who each vendor counts, not from the seat price.
This post gives you the formula, the 100-person example, a table you can copy, and the cases where the gap is small. Prices are list prices as of October 2026.
Count responders and notification-only users separately
Responders acknowledge, escalate, and close incidents, edit schedules, and read analytics. They need full access.
Notification-only users need to know when their systems are involved. Think developers, QA, DBAs, security, business owners, and managers. They need a phone call, SMS, email, or chat message, not a login. In most organizations, this group is larger.
If every notification recipient needs a full seat, you either pay for everyone or shrink the notification list. Shrinking the list saves money but means the right people miss critical incidents.
How each vendor bills
Flashduty licenses only members who view and handle incidents. Members who only receive notifications don't need a license. Professional lists at $29 per user per month on the pricing page. Standard and Professional don't cap users, schedules, workspaces, or daily alert volume.
| Flashduty item | Standard | Professional |
|---|---|---|
| Free SMS per license per month | 500 | 1,000 |
| Free voice minutes per license per month | 50 | 100 |
| Free emails per license per month | 2,000 | 5,000 |
Quotas pool across licenses. Overage in China is ¥0.05 per SMS, ¥0.12 per voice minute, and ¥0.0018 per email. Webhooks are unlimited. The Free plan allows five users, one schedule, one workspace, and 100 alerts per day. According to the pricing docs, Free silently drops alerts above that limit, so use it only for evaluation.
PagerDuty counts every person in the account as a paid user, including people who only receive notifications or appear in a schedule. That's from the FAQ on its Incident Management pricing page. Professional is $21 per user per month and Business is $41, billed annually ($25 and $49 monthly).
PagerDuty offers a cheaper option for people who don't respond. Stakeholder licenses give read-only access and, on Business, incident subscriptions. They start at $150 per month for 50 users and are sold in tiers of 50, 250, 500, 1,000, and 5,000. Only the first tier's price is public. Stakeholders can't be paged.
Add-ons are separate. AIOps starts at $699 per month and PagerDuty Advance at $415 per month, annual commitment only. Professional includes one external status page with up to 250 subscribers. More status pages and live call routing cost extra. PagerDuty's paid plans include unlimited SMS and phone notifications, according to its billing docs.
The 100-person example
| Person type | Count | Handles incidents |
|---|---|---|
| Frontline SRE and operations on-call | 8 | Yes |
| Core development owners | 5 | Yes |
| Team leads and platform admins | 2 | Yes |
| Other developers, QA, DBAs, security, and business contacts | 85 | No, notifications only |
| Option | Calculation | Monthly | Annual |
|---|---|---|---|
| Flashduty Professional | 15 × $29 | $435 | $5,220 |
| PagerDuty Business, full seats | 100 × $41 | $4,100 | $49,200 |
| PagerDuty Business + Stakeholders | 15 × $41 + 2 × $150 (assumption) | about $915 | about $10,980 |
The Stakeholder row assumes two 50-user packs. If PagerDuty requires the 250-user tier for 85 people, the cost is higher, and that price isn't public. Ask PagerDuty sales for a quote.
The two PagerDuty rows don't cover the same thing. With Stakeholders, the 85 people follow incident updates but can't be paged. With Flashduty, all 100 people can get phone and SMS alerts. So Flashduty costs about 89% less than full seats and about 52% less than the Stakeholder setup. Neither figure includes PagerDuty add-ons or Flashduty communication overage.
With 15 Professional licenses, the pooled Flashduty quota is 15,000 SMS, 1,500 voice minutes, and 75,000 emails per month.
A cost table you can copy
| Row | How to fill it in |
|---|---|
| Total headcount to notify | Example: 100 |
| Responders | People who acknowledge, escalate, close, or configure. Example: 15 |
| Notification-only users | Headcount minus responders. Example: 85 |
| Must notification-only users be paged? | If yes, PagerDuty needs full seats for them |
| Flashduty cost | Responders × license price × 12, plus communication overage |
| PagerDuty cost | Full seats × plan price × 12, plus Stakeholder packs and add-ons |
| Add-ons | AIOps, PagerDuty Advance, status pages, live call routing |
| Currency | If you compare USD with CNY, write down the exchange rate you assume |
When the gap is small
- Everyone responds. A team of 5 to 10 where every person handles incidents pays for everyone on either platform.
- Stakeholders are enough. If notification-only people only need to follow updates and never need a call, PagerDuty with Stakeholder licenses narrows the gap.
- Enterprise contracts. With private deployment, large add-ons, or negotiated discounts, compare actual quotes, including support and rollout.
Your plan choice also changes the cost. Model at least Standard for production on-call with noise reduction and escalation. If you need Feishu, DingTalk, or WeCom integrations, AI summaries, war rooms, or ticketing, model Professional. For plan details, see the pricing page.
Test with your own workload
Run a 14-day trial with a real system. Connect one alert source, set up schedules and escalation, and send SMS, voice, chat, escalation, and close once each. Then compare alert volume, notification volume, responder count, and response times.
