One site, five-minute basic connectivity, REST/AJAX, Agent and TLS state, opening/recovery email, and seven days of visible history.
What happens after trial
Without a valid reservation, the workspace falls directly to Free. Excess sites are paused rather than deleted, and AI exhaustion never disables deterministic monitoring.
Plan comparison
Choose by scale—not by hidden monitoring gaps.
Every plan keeps deterministic monitoring authoritative. Paid plans primarily expand site capacity, history, frequency, team access, and diagnosis allowances.
Swipe horizontally to compare every plan.
| Capability | Free | Starter | Pro | Agency+ |
|---|---|---|---|---|
| Monitored sites | 1 | 3 | 10 | 25–50+ |
| Visible history | 7 days | Expanded | Expanded | Expanded |
| Monitoring frequency | 5 minutes | More frequent | More frequent | More frequent |
| AI diagnosis | Not included | Included allowance | Larger allowance | Largest allowance |
| Team and integrations | Not included | Limited | Expanded | Agency scale |
Detailed quotas and advanced monitor entitlements remain visibly labelled in the reservation screen while beta capacity is measured.
Questions
Pricing FAQ
When does the trial begin?
Only after the first successful Firefly Agent pairing—not when you register or create a workspace.
Will I be charged for a reservation?
No. A reservation collects no payment method and grants no future charge authorization.
What happens to excess sites?
They are paused rather than deleted if the workspace falls back to Free.
What if the AI allowance is exhausted?
Deterministic checks and incident monitoring continue. AI never controls basic health monitoring.
Start with one WordPress site.
The beta starts with a 15-day trial, requires no payment card, and falls back to Free.
