Full review
Trellus solves a problem the rest of this list ignores: your team already lives in Outreach or Apollo, the sequencing is fine, and the dialing is the only bad part. Trellus is a Chrome extension that fixes the dialing without a migration.
Pricing on the current page is $99.99 a month for Power, single line, and $149.99 for Parallel with up to five lines, both frequently promoted at a much lower rate. A Business tier is quote-based. Third-party guides from late 2025 list a free tier of 30 power dials a week and a $59.99 Power plan; those no longer appear on the pricing page, so the pricing changed in 2026 and the free tier appears to be gone. Check the page before you budget.
What makes it different
It works inside Salesforce, HubSpot, Outreach, Salesloft, Apollo, Clay and Google Sheets, as a layer rather than a destination. There is no data migration, no second system of record, and no argument with RevOps about where the truth lives.
Dialing from a Google Sheet is genuinely rare and genuinely useful. If your list is a spreadsheet, almost nothing else on this list will call it without an import step.
The real-time coaching is the standout feature. During a live call, Trellus surfaces talk-ratio, pacing and objection prompts. For a ramping rep that is more useful than a post-call summary, because the correction happens while it can still change the outcome.
Where it is fragile
Browser extension reliability is the most common complaint, and it is structural. An extension depends on the host page not changing, and Salesforce and HubSpot change constantly.
There is no SMS, no email and no CRM. Trellus is deliberately a thin layer, which is the point and also the limit.
The G2 sample is very small, around 4.3 on few reviews, so there is little public evidence to weigh.
The price question
Five-line parallel dialing at $149.99 undercuts Salesfinity by half and Orum by more, with no seat minimum. That is a serious value proposition for a team that wants parallel dialing on top of an existing sequencer.
Single-line at $99.99 is harder to justify. That is more than JustCall's full Pro tier with unlimited minutes and a hundred integrations, and roughly three times what a bring-your-own-Twilio dialer costs for three seats. You are paying for the coaching layer and the no-migration property, and those are worth something, but $99.99 a seat is a real number for a browser extension with no system of record behind it.
Buy Trellus for the parallel tier and the coaching. Do not buy it as a general-purpose dialer.
Trellus FAQ
- How much does Trellus cost?
- Trellus's pricing page currently lists Power at $99.99 a month for single-line dialing and Parallel at $149.99 for up to five lines, both frequently promoted below list, with a quote-based Business tier. Third-party guides from late 2025 list a free tier of 30 power dials a week and a $59.99 Power plan; those no longer appear on the pricing page, so the pricing changed in 2026 and the free tier appears to have been discontinued.
- Does Trellus work with Google Sheets?
- Yes. Trellus is a Chrome extension that dials from Salesforce, HubSpot, Outreach, Salesloft, Apollo, Clay and Google Sheets, which makes it one of the few tools that will call a spreadsheet without an import step. That is its main structural advantage: it adds dialing to the system you already use rather than asking you to migrate.
- Does Trellus have a free plan?
- No. Trellus has neither a free plan nor a publicly advertised free trial.
- Can you bring your own Twilio account to Trellus?
- No. Trellus provides the telephony itself, so minutes are billed inside the seat price rather than at wholesale. Sales dialers that do support bring-your-own-Twilio include DialSheet and Myphoner.
- Who is Trellus best for?
- Trellus is best for reps who want dialing inside a sequencer they already pay for, without changing systems. It is a poor fit for teams that want a system of record, because Trellus deliberately is not one.
Trellus alternatives
The tools most buyers compare Trellus against, and our full review of each.
DialSheet
Free plan available

A mature single-line power dialer with unlimited calling included, aimed at teams that dial constantly and want one predictable bill.
Kixie
From $35/user/mo

The default triple-line dialer for real estate prospecting, sold as a stack of separate line items that add up faster than the headline price suggests.
Myphoner
From $27/user/mo
