Can I migrate from Bland to Open?

Yes. The migration work is reproducing your prompts, flow logic, and tool list in Open's configuration. The carrier and CRM integrations Open ships save weeks vs. starting from scratch.

How does latency compare?

Both run sub-200ms median first-token latency in US/EU regions. The two stacks are within noise of each other on most calls.

Does Open lock me into specific LLMs or voices?

No — voice cloning via ElevenLabs, custom voices, and bring-your-own-model deployments are supported on enterprise plans.

Is per-resolution pricing always cheaper?

Not always — it depends on average call length. We're happy to compare on real call samples from your existing volume.

Can Open scale to high outbound volume like Bland?

500+ concurrent dials per agent is standard. Higher volumes are supported on enterprise plans.

01 — Overview

When should I pick Bland vs. Open?

Bland is best when your team wants to own the platform — when voice AI is your product or you have engineers who want low-level control. Open is best when voice AI is a feature you need on top of your business, with the carrier and CRM integrations already wired.

Bland AI is one of the strongest voice AI infrastructure platforms on the market. They've built a clean abstraction over SIP, LLMs, TTS, and tooling, and a sharp API that developer teams enjoy working with. Their per-minute pricing is competitive and the latency on their stack is genuinely good.

Open positions differently. Open ships as a product: the SIP layer is integrated against 37+ carriers (so you don't write the carrier integration), the tool layer ships with ~50 official integrations (Salesforce, HubSpot, Zendesk, Stripe, Calendar, Shopify, Slack, Jira), the observability is included (recording, transcript, reasoning trace, outcome tags, PII redaction), and compliance is done (SOC 2 Type II, GDPR-aligned, HIPAA- and PCI-ready). You configure an agent — you don't assemble a stack.

The hands-on test is whether the team building this is a developer team or a business team. Developer teams asking "how do we wire a voice agent to our infrastructure?" will get more out of Bland's API. Business teams asking "how do we put an AI on our existing phone line for sales/support/reception by next week?" will get more out of Open.

Pricing reflects the positioning. Bland's per-minute pricing is transparent and aligned with what you use. Open's per-resolved-conversation pricing is more predictable for business use cases where conversation length varies. Carrier minutes in both cases stay invoiced by your carrier with no markup.

We've seen teams use both. The internal-facing or highly-custom agent goes on Bland; the customer-facing receptionist or call-center agent goes on Open because it ships with the integrations and compliance the business side requires. They co-exist.
