Splynx is one of the better-known commercial ISP management platforms — mature, feature-rich, with cloud and on-prem options and a module/subscription pricing model. ISP Boost takes a different angle: a fully self-hosted, all-in-one platform that's free to start and licensed once per server. Here's where each shines.
Pricing model: subscription vs one license
Splynx typically charges an ongoing subscription that scales with your customer count and the modules you enable. That's predictable for some, but it grows as you grow. ISP Boost is free for your first 50 users, and paid tiers are a single flat license per server — the whole product, not a per-seat meter. If you're cost-sensitive or scaling fast, the difference compounds.

Hosting & ownership
Both can run on your own infrastructure. ISP Boost is built to be yours end-to-end — one command installs the full stack (PHP, MySQL, Redis, nginx, FreeRADIUS) on a plain Ubuntu box, on any cloud or bare metal, anywhere in the world. Your data never leaves your server, and there's no seat meter phoning home.
Self-hosted means the subscriber database, invoices and RADIUS logs live on your server. Back it up, move it, own it.
Who each is for
Splynx is a solid pick if you want a large established vendor with a broad module marketplace and are comfortable with subscription pricing. ISP Boost is the better fit if you want the complete business suite included, a genuine free tier to start, self-hosting without per-user fees, and a one-click path off legacy systems like SAS Radius.
