The short version
- Each has a real cost: Gaggle pricing is quoted per student per year with no published rate, and because it is charged on total enrolment rather than on accounts actually monitored, small districts pay a markedly higher effective rate than large ones.; SkySafari the three tiers are separate purchases, so upgrading from Basic to Plus or Pro later means buying again rather than paying the price difference.
- They diverge on capability: Gaggle covers Content scanning, SkySafari covers Tiered editions.
- Prices and features above were last checked on 1 September 2026.

- A buyer choosing Basic first as a cheap star chart with no intention of telescope controlnot Gaggle
Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Gaggle
- Pricing is quoted per student per year with no published rate, and because it is charged on total enrolment rather than on accounts actually monitored, small districts pay a markedly higher effective rate than large ones.
- False positives are structural, not a tuning problem: fiction assignments, song lyrics, health coursework and jokes between friends all trigger review, and each escalation consumes counsellor time the district funds itself.
- The service reads children's private writing on school accounts, and civil liberties groups have documented cases where flagged content led to outing LGBTQ students or to discipline rather than support, which is a governance risk a board must accept explicitly.
- Coverage is limited to district-issued accounts, so a student using a personal phone, a personal email address or an encrypted messaging app is invisible, which is where much of the behaviour the district worries about actually happens.
- Escalation depends on the district maintaining accurate contact lists and staff who answer calls; when a named contact leaves and the list is stale, the service escalates into a void and the district only discovers it after an incident.
SkySafari
- The three tiers are separate purchases, so upgrading from Basic to Plus or Pro later means buying again rather than paying the price difference.
- Even the Basic tier costs more than a comparable free or freemium app like Star Walk 2 for a casual user.
- Telescope control only works with compatible motorised mounts, so it is useless to someone with a manual telescope or no telescope at all.
- Pricing fluctuates with frequent promotional sales, so the list price is not a reliable guide to what most buyers actually pay.
- The interface, particularly on the Pro tier, has a steeper learning curve than a simple AR sky map app aimed at casual users.

Answered from the vendors’ own pages
Gaggle: How much does Gaggle cost?
It is quoted per student per year based on enrolment and requirements. No rate card is published, and effective rates fall substantially with district size.
SkySafari: What is the difference between Basic, Plus and Pro?
Basic is a simple star chart, Plus adds a much larger catalogue and telescope control, and Pro adds an even larger catalogue and advanced planning tools.
Gaggle: Is the tipline an extra charge?
No longer. From 1 July, districts on the full Safety Management solution get SpeakUp for Safety and the web filter safety integration at no additional cost; each previously carried a per-student charge.
SkySafari: Can I upgrade from Basic to Plus later?
Not as a discounted upgrade; each tier is sold as a separate one-time purchase.
Gaggle: Do humans read every alert?
Trained reviewers assess flagged items before escalation. That human layer is the core of the service, not an optional tier.
SkySafari: Does it work with any telescope?
Only telescopes with compatible motorised mounts and a supported connection method can be controlled from the app.
Gaggle: Does it monitor personal accounts or phones?
No. It covers district-issued Google or Microsoft accounts. Personal devices, personal accounts and encrypted apps are outside its reach.
Gaggle: What are the privacy obligations?
Districts sign a data processing agreement covering FERPA and applicable state student privacy law. Negotiate retention and scope in that document rather than relying on the marketing page.
