Explore Splynx capabilities

A closer look at what broadband businesses use in Splynx every day.

Configure every CPE from your desk

With the TR-069 ACS add-on, Splynx provisions a new router on its first connection, upgrades firmware on selected devices in one action, and lets subscribers reboot their own router from the portal. Fewer trucks. More uptime.

RADIUS that works with your equipment

FreeRADIUS ships bundled and pre-configured with Splynx: PPPoE, IPoE, MAC authentication and IPv6 delegation work with RADIUS-compatible hardware from any vendor. When an invoice goes unpaid, the customer can be blocked automatically and redirected to a page where they can pay.

Bill subscribers on every continent

Splynx integrates with 17+ payment gateways, including Stripe, GoCardless, SEPA, Safaricom M-PESA, PayFast, Paystack and Moneris, plus accounting sync with Xero, QuickBooks, Sage, NetSuite and Zoho. Prepaid, usage-based and VoIP charges can go on one invoice.

Pricing you can check before you call

Splynx publishes its prices: $255 per month for up to 400 active subscribers, including hosting, updates, technical support and every feature. The license grows in steps of 100 subscribers, and paying yearly takes 10% off the license. Estimate your cost in the pricing calculator.
