Pick Authentic8 Silo if

- Makes sense if you need research traffic to come from chosen regions
Look elsewhere if
- Pricey if you are one person: the lowest tier is $1,450 per user a year for one region
- Skip it if you want everyday browsing: Authentic8 says it is not a VPN, VDI or enterprise browser
- Tight if you need AI: Nexus AI is capped at 10 prompts a day on the listed tiers
- Watch out: the price rises with regions, to $3,450 for all of them
- Watch out: the trial has limited egress nodes
Pick Kasm Workspaces if

- Makes sense if your team already runs Docker or Kubernetes servers

- Not for you if you use it commercially on the free tier: Community is for individuals, nonprofits and non-commercial use
- Tight if you need more than 5 concurrent sessions on Community
- Watch out: paid editions require a standard support subscription
- Too heavy if you do not run servers: self-hosting means installing on a Linux server you run

How this page was made
- The verdict at the top follows a fixed rule. When both tools are in the same category and either is in our top three for it, the verdict follows that ranking: the higher-placed tool is our pick. The top three weigh who each tool suits as well as its grades, so a pick can go against the GPA. Otherwise the page does not pick one and says which grades higher: the higher GPA first; on a tie, the one with a free plan, then the one that starts cheaper in dollars a month, counted the same way for both; if they are still level, what the choice depends on.
- The grades are our own, from each tool’s review or report card. The GPA is their average.
- Prices, plans and platforms come from each tool’s listing. The table above says where each price was read and when.
- The differences and the answers to the questions are worked out from those listings.
