If you run MikroTik routers in India and you are looking for a Splynx alternative, the short answer is Centipid: a hosted billing platform for MikroTik networks, with UPI collection through Razorpay, SMS on India's DLT rails, and PPPoE, hotspot and static IP billing from one account against the same routers. This guide explains where the two differ and how to move across without dropping a subscriber.
Why Indian operators look for an alternative
Splynx describes itself as an all-in-one ISP platform: billing, CRM, network management and helpdesk in one system. For an Indian operator whose network runs on MikroTik, three things tend to get in the way.
You pay in licence steps. Splynx prices by active customers in steps of 100, from an entry licence of up to 400 subscribers, in US dollars. Growth arrives one subscriber at a time; a stepped licence charges for the whole block.
Configuration is billed by the hour. Its pricing page includes two hours of setup help and sells more in five-hour packages. That is fair for a platform with that much surface, but it adds to the bill before the first subscriber has paid.
The Indian rails are the operator's problem. UPI reconciliation and DLT-registered SMS are what make billing work in India, and an operator should check that any platform handles both before signing, not after.
Centipid is built around the billing loop on MikroTik: the payment arrives, the subscriber is reconnected and the ledger is written, with nothing for you to host or maintain.
What Centipid does on a MikroTik network
Centipid sits between your payment rails and your routers. The router asks RADIUS whether a subscriber may connect; Centipid decides the answer from the subscriber's package, balance and expiry, and changes it the moment a payment lands.
- PPPoE subscribers on monthly plans, suspended on expiry and restored on payment, with speed profiles applied through RADIUS.
- Hotspot vouchers sold in bulk, through agents or per session from a captive portal, in the same ledger as your monthly customers.
- Static IP customers billed on the same cycle as everyone else.
- Unlimited routers and staff accounts on every plan. Nothing is charged per device, per seat or per site.
- Router health over SNMP, with an alert the moment a router stops answering and the lost minutes credited back to the subscribers behind it. See router monitoring.
You keep configuring your MikroTik the way you do today. Centipid drives the same RouterOS features over RADIUS and adds invoicing, payment matching, reminders and a subscriber portal around them.
The two things India needs that most platforms leave to you
UPI that reconnects the subscriber
Indian subscribers pay by UPI. Accepting it is easy; matching it to the right account is the part that usually stays manual, which is why so many operators still live on WhatsApp screenshots.
Centipid collects through Razorpay. One payment link takes UPI, cards, netbanking and wallets. The confirmed payment is matched to its invoice and renews the subscriber on its own, so nobody opens Winbox to switch a customer back on.
SMS that is actually delivered
Under TRAI's DLT rules, a commercial SMS from an unregistered entity, header or template is dropped at the carrier. The delivery report can still say sent.
Centipid sends through MSG91 and Fast2SMS on DLT with your own registered header and templates. If you are just starting and would rather not register yet, TextBee sends from an ordinary Android handset. The India guide covers the DLT steps in more detail.

What it costs
Centipid charges $0.25 per active PPPoE subscriber a month, or a share of the revenue your hotspot takes. Run both and the two fees arrive on one invoice. You pay for the subscribers who are active that month, not for the next licence step. The pricing page has the current rates and a calculator, and the trial runs 14 days with no card.
Moving across without dropping anyone
Subscribers, packages and balances import from a spreadsheet, and we plan the cutover with you around your billing dates. The safe order is the same for every migration:
- Start your DLT registration first. Template approval takes days, and it is the step most likely to hold up a launch.
- Connect one router to Centipid over RADIUS and leave the rest where they are.
- Move a small group of subscribers onto it and let them run a full cycle: expiry, reminder, UPI payment, reconnection.
- Test a real UPI payment end to end, not a sandbox one.
- Move the remaining routers once that cycle has run cleanly, then switch off the old system.
Twenty subscribers through one real cycle will tell you more than a month of comparing feature lists.
Frequently asked questions
Is Centipid a drop-in replacement for Splynx on MikroTik? For billing, subscriber management, RADIUS, vouchers, reminders and router monitoring, yes. You point your MikroTik routers at Centipid's RADIUS and import your subscribers.
Does Centipid support UPI? Yes. Razorpay payment links accept UPI, cards, netbanking and wallets, and each confirmed payment renews the subscriber automatically.
Can I bill PPPoE and hotspot from the same account? Yes. PPPoE subscribers, hotspot vouchers and static IP customers all run from one account against the same routers.
Do I need to host anything? No. Centipid is hosted. You need your MikroTik routers and an internet connection to reach us.
