TLDR:
We compared Trillet, Bland, Retell, and Vapi across pricing, speed, features, scalability, and compliance. Trillet matches Bland on the lowest cost ($0.09/min) but adds faster sub-2000ms response times, outbound-first tools, and built-in compliance. Retell and Vapi trail with higher prices, slower responses, or missing outbound essentials.
Pricing & Value Trillet and Bland both come in at $0.09 per minute, while Retell and Vapi top the list with an average extra charge of $0.135 per minute. That might not seem like much, but it adds up quickly once you’re talking thousands of calls - I'll let you do the math.
Looking closer, Trillet delivers a strong ROI, with outbound-friendly features like retries, callbacks, and after-hours handling all built in. Bland, by contrast, falls short on several of these capabilities. For high-volume calling, those extra cents accumulate fast - and Trillet makes every one of them work harder.
Latency & Call Quality
Let me paint a picture - you’re on a call with a phone agent, answering questions one by one, but there’s an awkward pause between every exchange. By the third pause, you’re already frustrated, worn down from an already long day…yeah, not a great experience.
Unnecessary waits push leads and customers away, and no business wants that. When we tested the four platforms, we found Trillet consistently responds under 2000 ms, giving conversations a natural flow(and no awkward pauses). Bland and Vapi hover closer to 2500 ms. For teams dialing thousands of leads a day, those fractions of a second make the difference between a smooth pitch and a stilted one.
Outbound Features That Matter
This was easy to compare. Trillet easily wins the race. With offering outbound-heavy tools like automatic retries, callbacks, MCP support for multi-call campaigns, number masking, honeypot detection, AND after-hours handling (whew, that’s a lot).
Bland lacks most of these; Retell offers partial coverage, and Vapi is built more with inbound support in mind. If outbound is your bread and butter, Trillet is the only platform purpose-built for it rather than retrofitted.
Ease of Use & Scalability
Here's where businesses see the true value of having an AI phone agent - something that can handle multiple calls all at the same time. Gone are the days when we had one (overworked) employee taking in calls one by one. Trillet and Retell tie on the highest number of calls taken concurrently (around 20+), with Bland and Vapi at a close second, with taking almost half that amount.
It’s also worth noting that out of the four, Trillet is the only platform that can onboard without being technical at all, you can sign up and an AI assistant will simply help you create an AI agent without clicking your mouse. This is something that has created a lot of friction in the past for business owners who struggle to make AI agents and has resort to tutorials on YouTube.
For growing teams that want to scale without adding layers of complexity, these differences add up quickly - and make Trillet stand out.
Compliance & Trust
Compliance isn’t optional - it’s survival. We’ve covered speed, latency, and concurrency; now it’s time to look at the rules that really matter.
Trillet checks all the boxes with HIPAA, TCPA, and ACMA coverage. Retell and Bland narrow it down to just HIPAA, while Vapi technically offers it - but only at a steep $1,000 per month (ouch).
With compliance baked in as broadly as Trillet delivers, the winner here is pretty clear.
The Bottom Line If you’re running outbound-heavy operations, Trillet AI is the clear standout. It matches Bland on price, beats Retell and Vapi on cost efficiency, and layers in outbound-first features that the others simply don’t prioritise. Add in faster response times, strong scaling, and built-in compliance, and Trillet doesn’t just come out smarter - it comes out ready for the kind of scale most teams are chasing.
