Splynx Alternative: How PyroRadius Compares on ISP Billing and Management

Splynx has been a default choice for small-to-mid WISPs and FTTH operators for years — it's a known quantity, with a large installed base and a mature feature set. ISPs searching for alternatives are usually not doing so because Splynx is bad; they're doing it because they've hit a specific limitation: integration friction with existing FreeRADIUS setups, per-subscriber pricing that scales awkwardly, or a feature gap around a specific piece of network hardware they run.

Why ISPs Look for a Splynx Alternative

The recurring themes in ISP operator forums and WISPA (Wireless Internet Service Providers Association) community discussions tend to cluster around a few specific pain points rather than a general dissatisfaction:

• Billing and RADIUS/AAA living in systems that don't integrate cleanly, requiring manual reconciliation
• Monitoring for specific hardware (Huawei OLTs, MikroTik routers) needing a separate tool bolted on
• Per-subscriber pricing that gets expensive as the subscriber base grows past a few thousand
• CRM and support ticketing living outside the billing platform entirely

Direct Comparison

Capability	Splynx	PyroRadius
Billing + invoicing	✅ Mature, widely used	✅ Built-in
RADIUS/AAA integration	Via FreeRADIUS module, some setup overhead	Native, designed around FreeRADIUS from the ground up
Network hardware monitoring	Partner/plugin dependent	Built-in for common ISP hardware (OLT, router)
CRM + support tickets	✅ Included	✅ Included, same data model as billing
Pricing structure	Per-subscriber tiers	Per-unit, transparent — see PyroRadius pricing
Installed base / maturity	Large, long-established	Newer, purpose-built for the FreeRADIUS-first gap

Splynx's maturity and installed base are real advantages — a larger ISP with an already-working Splynx deployment and no acute pain point has little reason to migrate. The case for PyroRadius is strongest for ISPs specifically frustrated by billing/RADIUS integration friction or by needing several separate tools (billing, monitoring, CRM) to run day-to-day operations.

What "One Platform for ISP Ops" Actually Means

The core pitch of any all-in-one ISP platform lives or dies on whether the pieces genuinely share data or are just bundled under one login. The test worth applying to any platform, PyroRadius included:

1. Does a subscriber's billing status automatically reflect in their RADIUS session — i.e., does non-payment actually trigger a real disconnect without manual intervention?
2. Does network hardware monitoring feed into the same subscriber record as billing and support?
3. Can a support ticket see billing and connection history without switching tools?
4. What does migration off the platform look like — is subscriber and billing history exportable in a usable format?

FAQ

Is switching from Splynx to another platform disruptive? Any billing platform migration carries real risk — subscriber data, active RADIUS sessions, and billing history all need careful migration. This should be planned as a project, not a weekend switch, regardless of destination platform.

Does PyroRadius support the hardware most WISPs already run? PyroRadius is built around common ISP hardware including Huawei OLTs and MikroTik routers — worth confirming specific model support directly for a given deployment.

Is per-unit pricing actually cheaper than per-subscriber tiers? It depends on subscriber count and growth trajectory — per-unit pricing tends to scale more predictably as a subscriber base grows, but the specific numbers should be compared directly against current Splynx tier pricing for an honest answer.

Does PyroRadius replace a separate CRM and ticketing tool? Yes — CRM and support ticketing run on the same data model as billing and RADIUS, rather than as a bolted-on separate system.
