Where each one falls short

Acunetix

  • AWS Marketplace lists Acunetix Online Premium, published by seller Invicti Security, at $7,000 per year for 5 targets under a 12 month contract, where a target is one fully qualified domain, website, web app, API or web service
  • AWS Marketplace's Invicti listing shows Premium Support priced separately at $150,000 per year and Premium Support with Guided Success at $300,000 per year, on top of the base scanning licence

AI21 Labs

  • The free allowance is $10 of credit lasting 7 days rather than an ongoing free tier
  • Jamba Large is $2 per million input tokens and $8 per million output, so output-heavy work costs four times as much as input
  • Volume discounts, private cloud hosting and higher rate limits require a custom plan
  • Standard rate limits are not published
