The short version

  • Only Termly has a free tier, so it costs nothing to try first.
  • Each has a real cost: GNAT Pro no pricing published on website; requires contacting AdaCore directly for quotes; Termly a standard plan licenses one website, so an agency or a business with several brand domains multiplies the headline price by the number of sites and the cheap option stops being cheap at four or five domains.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

GNAT Pro

  • No pricing published on website; requires contacting AdaCore directly for quotes
  • Vendor indicates per-user, per-year subscription model but does not disclose specific costs

Termly

  • A standard plan licenses one website, so an agency or a business with several brand domains multiplies the headline price by the number of sites and the cheap option stops being cheap at four or five domains.
  • Generated policies are templates conditioned on questionnaire answers, so they describe the data practices you claimed rather than the ones your code performs, and a regulator comparing the policy to actual tracking finds the gap not the vendor.
  • Banner view limits apply on the lower tiers, and a site that spikes in traffic can exhaust its allowance mid month, which is the worst possible moment for consent handling to degrade.
  • It covers websites well but has little for mobile apps, so a company with an iOS and Android app alongside its site needs a second consent mechanism and a second consent record.
  • There is no data mapping, subject rights automation or vendor inventory, so any company that grows into real privacy programme obligations outgrows Termly entirely rather than upgrading within it.

Answered from the vendors’ own pages

GNAT Pro: How much does GNAT Pro cost?

GNAT Pro pricing is not published on the website. Customers must request a pricing quote by contacting AdaCore directly or speaking with a GNAT Pro expert.

Source
Termly: Does one Termly plan cover all my websites?

No. A standard plan licenses one website. Multiple domains need multiple licences or an agency arrangement, and this is the single most common surprise on the bill.

GNAT Pro: What is GNAT Pro licensing model?

GNAT Pro is sold on a per-user, per-year basis with no license locks. Customers can request pricing for their specific needs.

Source
Termly: Are the generated policies legally sufficient?

They are templates conditioned on your answers and are not legal advice. They are proportionate for a simple site and inadequate where actual data flows are complex or regulated.

Termly: Is there a genuinely free plan?

Yes, one basic policy, one site, 10,000 monthly banner views and quarterly cookie scans, with no card required.

Termly: Does it handle US state privacy opt-outs?

Yes, including a do not sell or share mechanism and regional rule sets, alongside GDPR consent for EU visitors.
