Is there a cheaper alternative to Splynx?

Yes. Splynx's entry license is $255/month, sized for up to 400 subscribers regardless of how many you actually have. ISPbox bills per subscriber from a $25/month minimum - $1 each for your first 50, $0.40 to 500, $0.30 beyond - so a 40-subscriber ISP pays $40 instead of $255.

Can I migrate my Splynx data to ISPbox?

Yes. Upload a Splynx ZIP backup, run a dry-run preview to see exactly what will be created, then import clients, services, finance, tickets and leads. If anything looks off, roll the import back with one click.

Which Splynx paid add-ons are included in ISPbox plans?

Network maps, monitoring, IPAM, inventory, alerts, messaging and the REST API are plan entitlements in ISPbox, not separate purchases. Splynx sells several of these as paid add-on modules on top of the license.

Does ISPbox support MikroTik like Splynx does?

Yes. ISPbox manages MikroTik RouterOS for PPPoE and Hotspot with RADIUS authentication, live speed changes via CoA without dropping sessions, WireGuard tunnel management and IPv6 prefix delegation.

Is there a subscriber limit on the $25 plan?

No. $25 is simply the monthly minimum and covers your first 25 subscribers. Beyond that you pay $1 per subscriber, dropping to $0.40 after 50 and $0.30 after 500 - a 100-subscriber ISP pays $70/month. Every feature is included at every size.
