The free offers Google and the assistants actually name
Page one for free power dialer is nine results and not one of them is independent. Read every one against the vendor's own pricing page and the word free turns out to mean five different things.
| Tool | What free actually is | The wall | What you pay to make a call | Auto-advances a list |
|---|
| Dialfire | No monthly fee at all, on any number of seats | No seat cap and no call cap | $0.0115 a minute on Dialfire's own routes | Yes, preview and predictive |
| Calley Personal | Free with no expiry, one user licence | 25 calls a day, 50-record list | Your own mobile minutes, because your handset places the call | Yes |
| DialSheet Free | Free forever, one user | 500 leads and 500 calls a month | About $0.014 a minute on your own Twilio account, plus $1.15 a month for a number | Yes, the full browser power dialer |
| Zoho Voice SOLO | A free plan with a monthly minute allowance | 250 free outgoing minutes a month | Call charges past the allowance, at rates the page does not render | No, the power dialer is an add-on |
| Agile CRM | Free for 10 users, no card | 1,000 contacts and companies, one plugin | Not published anywhere on the pricing page | No tier lists the auto dialer |
| PowerDialer.ai | Nothing at all | Not applicable | $45 a month buys 250 minutes, and unlimited US and Canada starts at $139 | Paid plans only |
Every figure above was read from the vendor's own pricing page: Dialfire, Calley, PowerDialer.ai and Zoho Voice on 22 September 2026, and Agile CRM from a 16 May 2026 archive snapshot, because its live page returned a Cloudflare 403 on two separate reads.
Two entries deserve naming. PowerDialer.ai ranks third for the phrase with a page titled "Free Power Dialer Software to Maximize Sales Productivity", and its own pricing page carries no free plan at all; the word free on that page attaches to a trial sign-up and a demo booking. And Allo's pricing article answers the question "Is there a free power dialer?" with "No reputable provider offers a permanently free power dialer; the feature always sits in paid plans." Two of the tools in the table publish one.
What this page got wrong until 23 September 2026
This page opened for three weeks by saying that exactly one power dialer has a permanently free plan that includes the dialer. That was too strong, and the table above is why.
DialSheet is the only permanently free browser power dialer with a CRM, which is the narrower claim and the checkable one. Dialfire charges no monthly fee on any number of seats and bills $0.0115 a minute, undercutting Twilio's $0.014. Its own feature list names a preview and predictive dialer and no power or progressive mode, and US predictive dialing carries the three percent abandonment cap, so it solves a different problem. Calley is free forever for anyone willing to hold a phone, at 25 calls a day.
Where DialSheet's free plan loses, with the number
The free plan stops at 500 calls a month and one user. Past either line it costs $29 a seat, and that is where Dialfire's arithmetic wins.
A three-person desk running 2,000 outbound minutes a month pays Dialfire $23, all of it minutes and nothing for software. The same desk on DialSheet Pro pays $87 in software plus about $31 at Twilio list, counting three local numbers, so $118. Dialfire is five times cheaper and its software stays free at any seat count and any call count.
Two things stop that being the whole answer. Dialfire publishes no price for a phone number, so $23 is a floor and the real bill is higher by whatever its numbers cost. And the dialing mode differs: predictive dialing drops calls by design and is capped at three percent abandoned in the US, so a desk working its own customer list is buying a different risk from one running a power dialer down a list.
Why almost nothing here is free
A dialer costs its vendor money on every call. If the vendor also sells you the telephony inside a seat price, a free plan means giving away minutes, and no company does that at scale. That is why this category is full of trials.
Two business models escape it, and the table above splits along that line.
The first is bring your own carrier. If the software never touches the phone call, giving the software away costs the vendor almost nothing. DialSheet never pays for your minutes; Twilio bills you for them directly, which is how a permanently free plan survives.
The second is selling the minutes instead of the seat. Dialfire charges no monthly fee and takes $0.0115 a minute on its own routes, so every call funds the product. That model can beat the first outright, because $0.0115 undercuts Twilio's $0.014 by about 18 percent, and it means the vendor's revenue climbs with your dial volume.
Any vendor that bundles minutes into a seat price and advertises a free power dialer is running a trial, a credit cap, or both.
What free actually costs
Free software still means paid calls. Here is the real monthly bill for one person dialing 100 numbers a working day on a free plan with their own Twilio account:
| Line item | Cost |
|---|
| Software | $0 |
| One local phone number | $1.15/month |
| ~1,000 billable minutes | ~$14/month |
| Total | ~$15/month |
That is the number, and it is still an order of magnitude below any paid tier in this category. A rep on PhoneBurner Standard pays $140 a month for software before making a single call.
Note the billing quirk that most cost calculators skip: carriers bill per call rounded up to the whole minute, and a voicemail that picks up bills a full minute even if you hang up after ten seconds. Unanswered rings cost nothing. At 100 dials a day with a 22 percent voicemail rate, that is about 22 wasted minutes a day you should budget for.
The caps to check before you commit
Every free plan has a wall. These are the ones that actually stop people:
- Lead cap. DialSheet's free plan holds 500 leads. If your list is 3,000 records, the free plan will not hold it, and that is usually the first reason people upgrade.
- Call cap. 500 calls a month is about 25 a working day. A serious full-time dialer will pass it in the first week.
- Seats. Free plans here are single user. Teams start at the paid tier by design.
- Recordings. On DialSheet's free plan, recordings live in your own Twilio console rather than in the app. That is a genuine limitation and also a genuine feature, because they are your files.
Free trials, ranked by how much you can learn
If a free plan will not fit, a trial is the next best thing, and their length varies more than it should.
- JustCall and Myphoner: 14 days. Long enough to work a real list, measure connect rates and see whether the tool holds up on your office network.
- CloudTalk and Dialpad: 14 days. Same, with the caveat that CloudTalk's dialers are add-ons you need enabled during the trial.
- Aircall and Ringover: 7 days. Enough to test setup and call quality, not enough to measure outcomes.
- Kixie: 7 days, no card. The no-card part is good practice.
- Orum: 500 dials. About one day of work for one rep. Not an evaluation.
The trial mistake almost everyone makes is spending the first four days on setup and the last day panicking. Import your list on day one, dial on day two, and decide by day five.
What to do if you outgrow free
The paid tiers here span an order of magnitude, so the upgrade decision matters more than the free decision.
The cheapest real upgrade for a team is a plan at $29 a seat, with telephony at wholesale. The cheapest mainstream upgrade is JustCall Pro at $49 a seat with unlimited minutes included. Everything above that is buying integrations, parallel lines or a CRM.
If you are upgrading purely because you hit a lead cap, check whether the cap is the only thing you need lifted. Several tools sell a much more expensive tier to solve that one problem.
