Pick Voiceflow if your support team needs voice agents as well as chat, wants to rehearse conversations before launch, and has designers, developers and CX people sharing one workspace. Pick Botpress if you want AI agents working inside Zendesk, Intercom, HubSpot or Salesforce, with its own escalation desk, or if your developers would rather build in TypeScript.
Three questions will settle most of this before you open a single demo. Answer them honestly and you'll know which of the two to shortlist.
- Will customers phone you, or only type? If calls matter, one of these sells voice agents and contact centre use cases outright. The other's home page shows webchat, WhatsApp and Slack.
- Where do your tickets live today? If the answer is Zendesk, Intercom, HubSpot or Salesforce, one platform is built to plug straight into those and adds its own escalation desk.
- Who's doing the building? A mixed team of CX leads and designers points one way. A developer who wants a TypeScript library points the other.
Keep your answers in mind. The rest of this page goes through each of those themes, then the smaller differences such as compliance claims, before landing on who should pick which.
Neither is a hobby chatbot builder any more
If you remember either of these as a general bot builder, it's worth resetting your expectations. Both home pages are now written for customer support teams, not for someone building a fun bot for a side project.
Botpress has moved towards an AI helpdesk story. It ships Botpress Desk, an AI helpdesk for escalations, so the agent and the desk come from one vendor. Voiceflow leads with Atlas, an AI copilot that builds, tests and improves the agent from plain-language requests, and its site says you can set it up by pasting a prompt into your own coding agent. So you're choosing between two support platforms with different centres of gravity, not two chatbot toys.
That matters because the decision isn't really about which builder is nicer to click around in. It's about whether your support operation revolves around voice and careful rehearsal, or around tickets moving through a helpdesk you already run.
Differences at a glance
| Theme | Voiceflow | Botpress |
|---|---|---|
| Channels | Chat, voice, SMS and API, with voice agents and contact centre use cases sold directly | Webchat, WhatsApp and Slack shown on the home page; voice isn't headlined |
| Building | Studio for team editing, the Atlas copilot, plus app, API, CLI and MCP | Viber (build by conversation), Studio (drag and drop) and ADK, a TypeScript library |
| Pre-launch testing | Rehearsal simulations, tests, evaluations, traffic splits and change review | Testing on your own support tickets; no separate simulation product shown |
| Handoff and helpdesk | Human handoff as a tool, with agent-assist and contact centre solutions | Botpress Desk for escalations, plus Intercom, Zendesk, HubSpot and Salesforce integrations |
| Who the site targets | Customer service, contact centre, CX and agent assist | Customer support, with SaaS, healthcare, education, retail and fintech listed |
| Compliance claims | SOC 2 Type II, ISO 27001, GDPR and HIPAA listed | SOC 2 compliant, per its home page |
Phone lines and other channels
This is the clearest split. The voice-first platform lists chat, voice, SMS and API as places to deploy, and it sells voice agents and contact centre work directly. If your customers ring you and you'd like an AI agent picking up some of those calls, that's the one with the stronger story.
The helpdesk-first platform's home page lists webchat, WhatsApp and Slack. Voice isn't something its home page puts forward, so if calls are central to your support, ask its team directly before you plan around it. If you mostly answer customers in a chat window or on WhatsApp, the gap won't matter much.
Who builds the agent, and how
Both give you a visual Studio, but the routes around it differ.
On the voice-first side, Studio is set up for team editing, so product, dev and CX people can work in one workspace. Atlas sits on top as the copilot you describe changes to in plain language, and there's also access through the app, API, CLI and MCP for teams who like to script things.
The helpdesk-first platform's docs describe three entry points. Viber lets you build by having a conversation, Studio is drag and drop, and the ADK is a TypeScript library for building from code. That spread is useful if your no-code support lead and your developer both want to work on the same agent in different ways.
Rehearsing conversations before customers see them
Here the voice-first platform has more to show. It lists Rehearsal, which simulates conversations, alongside tests and simulations, evaluations, traffic splits and change review. For a contact centre that can't afford an agent going off script on live calls, that kind of rehearsal tooling is a real draw.
The helpdesk-first platform stresses testing on your own support tickets, which is a sensible way to check answers against real questions. Its home page doesn't show a separate simulation product, though, so if structured rehearsal is high on your list, that's a point in the other column.
When a person needs to take over
Every support agent, human or AI, eventually hits a question it can't answer. What happens next is where these two differ in spirit.
The voice-first platform lists human handoff as a tool and positions itself as a standalone agent platform with contact centre and agent-assist solutions. The helpdesk-first platform goes further down the helpdesk path: its site says its agents take real action such as refunds and account updates, with a hot handoff to a human and learning from each resolution. It also ships its own desk for escalations and connects to the big helpdesks. If you already run one of those, you'll likely find the second option slots in with less fuss.
On compliance, the voice-first platform lists SOC 2 Type II, ISO 27001, GDPR and HIPAA, while the other's home page says it's SOC 2 compliant. If you're in a regulated sector, ask both for their current reports rather than relying on a logo strip.
Want AI doing the heavy lifting in your marketing?
I build the systems that handle the boring 80 percent, so you get your week back. Done properly, with the human kept in.
Three more AI agent platforms worth a look
If neither fits, these are the nearest alternatives. For a wider field, our roundup of the best AI chatbots for business covers many more.
Landbot
Best for: Marketing and sales teams capturing leads on WhatsApp and websites; the vendor says agents can be built from inside Claude, ChatGPT and Codex.
Rasa
Best for: Product and engineering teams in regulated industries such as banking, insurance and healthcare, with a Developer Edition to start from.
Dify
Best for: Teams that want to self-host agent workflows and RAG pipelines, with an open-source Community Edition you can deploy with Docker.
If you've ruled one of the main two out already, our list of other support agent builders in the same space goes deeper.

My advice for support teams
Choose Voiceflow if voice agents matter, if you want to rehearse conversations through simulations before launch, and if designers, developers and CX people need to share one workspace. Choose Botpress if your aim is support tickets handled inside Zendesk or Intercom with a desk for escalations, or if your developers want to build in code with the ADK. There isn't one winner for everyone here: your channels and your existing helpdesk should decide it.

Frequently asked questions
Which one is better for voice agents and phone support?
The voice-first platform sells voice agents and contact centre use cases directly and lists voice and SMS as deploy options. The other's home page shows webchat, WhatsApp and Slack, so check with its team if calls matter to you.
Can I build an agent in code rather than a visual editor?
Yes, on both, in different ways. One offers an ADK, a TypeScript library for building from code. The other offers access through its API, CLI and MCP alongside Studio.
Which works better with Zendesk or Intercom?
The helpdesk-first platform names integrations with Intercom, Zendesk, HubSpot and Salesforce and adds its own desk for escalations, so it's the more natural fit if those tools already run your support.
Is there a free trial?
One of the two states a free trial on its site. The other doesn't state one on its site, so check its sign-up page before you plan a pilot.
Which has more compliance certifications listed?
The voice-first platform lists SOC 2 Type II, ISO 27001, GDPR and HIPAA. The other's home page says it's SOC 2 compliant. Ask both for current reports if you work in a regulated sector.
