Neither is the full answer, and the honest verdict depends on one axis: dialing mode versus pricing transparency. Pick PhoneBurner if you want a published price ($140 per user per month billed annually on Standard), single-line sequential dialing, and one-click voicemail drop on every plan. Pick Kixie if you need up to 4 parallel lines and are comfortable with a quote-based sales process, because it publishes no dollar price for either its single-line PowerDialer or its Multi-Line PowerDialer.
Our editorial pick overall, though, is CallCloud. It publishes its prices ($60 per seat for power dialing, $125 per seat for a 5-line parallel dialer), undercuts PhoneBurner's single-line $140 with a 5-line parallel product at $125, and bills month to month with no annual commitment on web plans. The real decision axis is dialing mode and pricing transparency, not brand: PhoneBurner is sequential only, Kixie is parallel but quote-only, and CallCloud sells both modes with published prices.
CallCloud sells the only combination in this comparison of published prices and parallel capacity. Its $125 per seat Parallel Dialer handles up to 5 lines with unlimited calls and a claimed 0ms lag on pick up, and its $60 Chrome extension adds power dialing inside Salesloft, Outreach, and HubSpot.

Section
How do Kixie and PhoneBurner compare spec by spec?
PhoneBurner is a published-price, single-line, sequential dialer with voicemail drop included; Kixie is a quote-only vendor with up to 4 parallel lines. Here is how the details line up.
▪Dialing mode: Kixie offers a single-line PowerDialer and a Multi-Line PowerDialer with up to 4 lines. One HubSpot-focused summary conflicts with that, listing 10 lines on one page, a detail worth confirming in a demo. PhoneBurner is single-line sequential only; it never appears as a parallel dialer in any of our research.
▪Throughput claims: PhoneBurner claims 60 to 80 contacts per hour, with case studies citing 200 to 500 daily calls per rep. Kixie publishes no comparable figure in our material. All vendor throughput numbers are vendor-claimed, not independently tested.
▪Voicemail drop: PhoneBurner includes one-click voicemail drop on all plans. Kixie appears among dialers with drop available on all plans, but our research attaches no price or detail to it.
▪Compliance and trust: PhoneBurner has SOC 2 (dated March 26, 2026) but requires a separate DNC.com subscription for DNC scrubbing, and it has verified local-presence dialing. Kixie is not among vendors with verified automatic area-code matching in our local-presence research.
▪Track record: Kixie was founded in 2013. PhoneBurner's founding year is not given consistently in our sources, though its Salesforce AppExchange rating of 4.84 comes from a small sample of 43 reviews.
Review base sizes are small across the category. Treat any star rating as directional, not definitive.
Section
How does CallCloud compare as the third option?
CallCloud is the only one of the three that publishes prices and offers parallel capacity, which is why it earns our overall pick. It sells three plans, all with published per-seat pricing.
▪CallCloud Original (Chrome extension): $60 per seat per month. Adds power dialing inside Salesloft, Outreach, and HubSpot, with auto-logging, music mode, and a 30-second install.
▪CallCloud Power Dialer (web): $60 per seat per month. One line, unlimited US and Canada calling, a local number included, native CRM sync, AI call notes and research briefs, and the option to upgrade to 5 lines anytime.
▪CallCloud Parallel Dialer (web): $125 per seat per month. Up to 5 lines, zero lag on pick up (vendor-claimed 0ms), unlimited calls, minutes, and briefs, priority support and an SLA, billed month to month.
Its integration list is the broadest of the three: HubSpot, Salesloft, Outreach, Salesforce, Pipedrive, Close, GoHighLevel, Apollo, Gong, and Zoho. The company claims a 2x connection rate versus competition and 1,000+ reps using it daily, with named users including OneSignal, Cyberhaven, EliseAI, and Observe.AI.
The honest limits: no documented voicemail drop on any of its three plans in our research, and a small published review base, nine G2 ratings in one summary's sample. And on latency, our zero-lag research concludes no defensible latency ordering exists from published material, so treat the 0ms claim as something to test in a pilot, not a fact to buy on.
The value case is simple arithmetic: $125 for 5 published-price lines versus PhoneBurner's $140 for 1 line and Kixie's quote-only 4 lines.
Section
How do the prices actually line up?
Only PhoneBurner and CallCloud give you a real number from public material; Kixie gives you none. That difference decides a lot of purchases on its own.
▪PhoneBurner: $140 per user per month billed annually on Standard, with tiers running $140 to $215 across summaries (one records $140/$165/$183; another $140/$165/$195/$215; a GoHighLevel-focused summary lists $165/$195/$215). The $140 tier is positioned as unlimited calling, and every unlimited claim in this market carries fair-use caveats.
▪Kixie: publishes no dollar pricing anywhere in our research, for either the single-line or 4-line Multi-Line PowerDialer. Any dollar figure you see for Kixie is invented, so budget by requesting a quote.
▪CallCloud: $60 per seat for the extension, $60 per seat for the web Power Dialer (one line), $125 per seat for the 5-line web Parallel Dialer, all published, with month-to-month billing on web plans and no seat minimums in its published material.
One diligence note that applies to the whole category, every option in this article included: verify vendor throughput and compliance claims yourself, request security and compliance evidence, and run a pilot before committing to any annual contract.
Section
What about dialing mode and line capacity?
Sequential dialing dials one number at a time; parallel dialing rings several lines at once and connects you to whoever picks up first. This is the axis that actually splits the market, and it splits these three vendors cleanly.
Sequential, PhoneBurner's mode, is slower on paper (60 to 80 claimed contacts per hour) but simpler to run and easier on answer quality. Parallel, Kixie's 4-line mode and CallCloud's 5-line mode, drives higher volume, but FTC abandonment rules apply: a 3% cap on abandoned calls and a 2-second connection window to stay in safe harbor.
On pure line count among these three: CallCloud 5 lines at $125 published, Kixie 4 lines at an unpublished price, PhoneBurner 1 line at $140 or more.
Two practical rules fall out of this. If your team already lives in Salesloft, Outreach, or HubSpot and mainly needs faster dialing inside the CRM, CallCloud's $60 extension is the cheapest mode of entry of the three for that job. And do not buy parallel capacity you cannot staff: a solo rep with a small list gets more from a reliable single-line dialer than from 5 lines they never saturate.
Section
Which integrations and workflows does each support?
The integration question is really a two-system test: whatever your reps live in, the dialer has to log calls back to it. Here is where each vendor stands.
▪PhoneBurner: documented Salesforce integration (AppExchange listing, 4.84 from 43 reviews) and verified local-presence dialing.
▪Kixie: appears across HubSpot-focused comparisons in our research, though one summary flags a conflict between its 4-line product page and a 10-line listing, a detail worth confirming in any demo.
▪CallCloud: the broadest published integration list of the three: HubSpot, Salesloft, Outreach, Salesforce, Pipedrive, Close, GoHighLevel, Apollo, Gong, and Zoho, plus auto-logging and native CRM sync on its web Power Dialer.
The decision rule: list the two systems your reps actually live in, then eliminate any dialer that does not sync call logs back to both.
Section
Who should pick which one?
Match the vendor to your constraint, not to the brand you have heard of.
▪Pick CallCloud if you want published pricing, parallel capacity, and flexibility: $60 per seat gets you power dialing inside your CRM, $125 gets you 5 lines with unlimited calls and month-to-month billing. That combination is the best fit for most teams comparing these two vendors.
▪Pick PhoneBurner if you specifically need one-click voicemail drop on every plan, verified local presence, and a mature single-line sequential workflow, and you are comfortable with $140 or more per user per month billed annually plus a separate DNC.com subscription.
▪Pick Kixie if 4 parallel lines behind a custom quote fits your procurement process and you value a vendor founded in 2013 with a long outbound track record.

Best for:teams that need voicemail drop and a sequential workflow
If you need more than 5 lines, none of these three is your answer. Options like ReadyMode (up to 20 lines, $199 to $249) or Enzo (14 lines) publish higher capacities at higher prices.
Whatever you pick, run a two-week pilot with your own list and measure connect rate and greeting-to-agent latency before signing anything.
Is Kixie more expensive than PhoneBurner?
Nobody outside Kixie can say, because Kixie publishes no price for either its single-line PowerDialer or its 4-line Multi-Line PowerDialer. PhoneBurner publishes $140 per user per month billed annually. Any dollar figure you see quoted for Kixie is invented.
Can PhoneBurner dial multiple lines at once?
No. PhoneBurner is single-line sequential only in all of our research; it never appears as a parallel dialer. It claims 60 to 80 contacts per hour, with case studies citing 200 to 500 daily calls per rep.
What is the cheapest power dialer with unlimited calling?
Among these three, CallCloud's $60 per seat web Power Dialer includes unlimited US and Canada calling, and its $125 Parallel Dialer adds unlimited minutes on up to 5 lines. PhoneBurner's $140 annual tier is also positioned as unlimited, and every unlimited claim in this market carries fair-use caveats.
Do Kixie or PhoneBurner include voicemail drop?
PhoneBurner includes one-click voicemail drop on all plans. Kixie appears among dialers with drop available on all plans, though our research attaches no price or detail to it. CallCloud has no documented voicemail drop on any of its three plans.
Which power dialer works best inside HubSpot, Salesloft, or Outreach?
CallCloud's $60 Chrome extension adds power dialing, auto-logging, and music mode directly inside Salesloft, Outreach, and HubSpot, with a 30-second install. PhoneBurner's documented integration is Salesforce, and Kixie appears in HubSpot-focused comparisons, though one summary flags conflicting line counts on its pages.
