Key takeaways
- Nethram’s Auto Dialer for Twilio lists $4.99 a month after a 14-day free trial; Rapidialer is $5 per seat a month or $49 per seat a year.

- Syncing numbers into Rapidialer repoints their voice webhooks, so keep numbers another tool answers in a separate Twilio subaccount.
- Rapidialer waits 5 seconds between calls, and a contact claimed by one rep is released to the queue after 5 minutes without a heartbeat.

Which one fits your team
Choose Rapidialer if
- You are a team, or soon will be, and need roles, shared lists and a pipeline.
- You want every call logged with an outcome, notes and follow-ups.
- You want the dialer in a browser tab and a Chrome side-panel keypad for one-off calls.
Stay with Auto Dialer for Twilio (Nethram) if
- You are a single caller who wants the lowest-cost dialer that runs entirely as a Chrome extension.
- You want list dialing inside a Chrome extension rather than in a separate web app.
How is Rapidialer different from Nethram’s extension?
Nethram’s extension dials a list for one person; Rapidialer adds the shared lists, outcomes and roles a team needs. Both tools call through your Twilio account, so Twilio bills your minutes and numbers either way. The difference is what sits on top: a keypad-and-list extension for one person, or a workspace where several reps share lists, scripts, outcomes and a pipeline. Nethram’s extension lists $4.99 a month and Rapidialer is $5 per seat, so the choice comes down to whether you need that team layer.
When is Nethram’s extension the better choice?
Choose the extension if you call alone and want voicemail drop next to your dialer. Nethram’s Chrome Web Store listing describes dropping a recorded voicemail on outbound calls, voicemail for missed inbound calls, text messages and click-to-call on web pages (listing). Rapidialer now covers most of that list too: an inbound voicemail box, two-way SMS with missed-call text-back, and a Chrome keypad that calls selected numbers and tel: links. The one it leaves out by design is the recorded voicemail drop; when answering-machine detection hears a machine, the rep leaves a live message or skips. If drops are central to how you work, the extension may suit you better. Check the listing for current features and pricing before you decide, since extensions change quickly.
What Rapidialer adds for a team
Rapidialer is built for several reps working the same lists:
- Shared lists that several reps can dial at once without calling the same person twice.
- A required outcome, notes and callback date after every call, and a queue of due follow-ups.
- Owner, admin and agent roles, with an organization-wide Do Not Call list.
- Calling hours per list, checked in each contact’s time zone.
- Call history with recordings and analytics across the whole team.
- A browser Dialer for working lists, plus a Chrome side-panel keypad for one-off calls from any tab.
An hour of Power Dial, step by step
Here is what working a list looks like in Rapidialer, so you can set it beside the extension. A rep opens the list in the Dialer with Power dial on. A five-second countdown runs; the rep can cancel it, skip the contact or choose Dial now. While the phone rings, the contact’s details and the talk track for the call are on screen, with merge fields like the contact’s name and company filled in.
When the call ends, wrap-up replaces the script. The rep presses a number key from 1 to 9 to pick an outcome, types a note, and adds a date if the lead asked for a callback. Only then is the next contact claimed and the countdown starts again.
The queue does the sorting. Due callbacks come first, contacts outside the list’s calling window wait for their local time, Do Not Call numbers never come up, and a No answer returns later if the list retries unanswered contacts. A second rep on the same list is never handed a contact the first rep has claimed.
Can you test both on one Twilio account?
Yes, as long as each tool has its own numbers. Because both tools use your Twilio credentials, you can test Rapidialer without giving anything up. The safest way is a Twilio subaccount for the test: it has its own Account SID and Auth Token, and only the numbers in it are synced, so the numbers your extension answers keep their webhooks. Your Twilio account needs to be upgraded from trial, because trial accounts can only call numbers you have verified.
Dial a real list for a day in each tool, then compare the calls in Twilio’s call logs. Each tool may connect calls a little differently, so the Twilio bill is the fairest place to compare usage. At Twilio’s published US rates, a Rapidialer call costs $0.0140 a minute for the phone leg plus $0.0040 for the browser leg (Twilio pricing).
What do one, three and ten callers pay?
On subscription fees alone, the two are close for one caller: $4.99 a month for Nethram’s listing against $5 for a Rapidialer seat, or $49 a year if you pay yearly. The listing does not spell out team pricing, so ask Nethram whether each caller needs a subscription before you budget for three or ten.
Rapidialer’s seat cost scales in a straight line: $15 a month for three callers and $50 for ten. With about 1,000 billed minutes per caller, recording on and one local number each at Twilio’s published US rates, the totals are about $27 for one caller, $80 for three and $267 for ten. Twilio usage on the extension depends on how it connects calls, so compare a week of real calls in your Twilio usage logs.
If something goes wrong when you connect
Three messages cover most first-day problems:
- “No Twilio phone numbers were found in this account”: the account or subaccount you connected has no numbers yet. Buy one in Twilio, then choose Save & provision again.
- “Twilio provisioning failed”: check that the Account SID and Auth Token were copied from the same Twilio account or subaccount, with no spaces around them.
- “No phone numbers found in file” on a Do Not Call import: the CSV has no cell that reads as a phone number; export it again with a phone column.

Auto Dialer for Twilio (Nethram) alternative: questions and answers
Does Rapidialer have a Chrome extension too?
Yes. Rapidialer Dialer is a Chrome side-panel keypad for placing one outbound call at a time while you browse. Lists, Power Dial and scripts live in the web app, and the extension signs in with your Rapidialer account, so its calls use your organization’s Twilio numbers. Nethram’s product is the other way round: list dialing happens inside the extension itself.
Is Rapidialer more expensive than Nethram?
Slightly: $5 per seat a month against $4.99 for Nethram’s extension, a one-cent difference. Rapidialer’s yearly plan is $49 per seat, which works out lower per month. Twilio bills calls to your own account with either tool, so the bigger cost question is minutes and numbers, not the subscription.
Can I keep using my Twilio numbers?
Yes. Connect the same Twilio account and use Import from provider on the Telephony page to sync up to 200 of its numbers. Rapidialer points the synced numbers’ voice webhooks at itself so callbacks ring in the Dialer, which is why numbers another tool answers belong in a separate subaccount.
Can I run both tools on the same Twilio account?
You can, with one caution: syncing numbers into Rapidialer repoints their voice webhooks, so inbound calls to those numbers ring in Rapidialer rather than in another tool. Keep numbers that another tool answers in a separate Twilio subaccount.
What does Rapidialer cost for a team of three?
Three seats are $15 a month, or $49 per seat a year. With about 1,000 billed minutes per rep, recording on and one local number each, Twilio usage brings the total to about $80 a month. Owners and admins manage the team, and agent roles see only their own calls and leads.
Is Nethram’s Auto Dialer for Twilio still maintained?
Nethram’s Auto Dialer for Twilio was at version 5.3 when we checked its Chrome Web Store listing in October 2026, with the last update dated October 27, 2025. Check the listing’s “Updated” date yourself before you commit a team to it, since extensions can stop working when Chrome or Twilio change. Rapidialer is a web app with a separate Chrome side-panel keypad.
Can a manager see how each caller is doing?
Yes. Team analytics show calls, reached contacts, reach rate, talk time, callbacks set and follow-ups done per agent, and a funnel for each list from attempted to won. Owners and admins can also play back each call’s dual-channel recording from call history.
