I opened Voiceflow's pricing page to budget for a client's support bot, but I couldn't find any prices. The page offered a demo for businesses and a free trial for agencies, but not a single dollar figure.
That was the first problem. The second was the credit model. Chat messages, phone minutes, and AI model use all draw from one pool, so the monthly bill depends on how many customers actually use the bot. Hard to predict before launch. Plus, Voiceflow's phone features have far less depth than its chat builder.
So, I tested many Voiceflow alternatives and picked six. Some replaced Voiceflow outright. Others beat it at one specific job.
Here is what I found.
Teams leave Voiceflow for unclear pricing, usage-based costs that are hard to predict, and limited depth for phone calls. Voiceflow remains a strong canvas for designing chat conversations. These limits, however, push many teams toward tools built for one specific job.
These are the limits that come up most often:
A good Voiceflow alternative is easier to build, test, and pay for. Voiceflow remains strong at visual conversation design, so each tool on this list had to win on a narrower task: a support chatbot, a phone line, or the internal follow-up work that comes after a customer call.
I tested each tool on the task it was built for. I rebuilt a Voiceflow support bot in Botpress, trained Chatbase on a test help center, and asked Lindy to close out a sales call in Slack. On the voice side, I built appointment-booking and reminder calls in Synthflow, Retell AI, and Bland AI, then checked each agent before any real caller dialed in.
Every tool was judged on the same five criteria:
If you mainly use Voiceflow for chat, these three tools cover the same ground from different angles. Botpress suits teams with a developer, and Chatbase suits teams that want a bot trained on their help content. Lindy works inside Slack as an AI teammate for internal work. It covers the follow-up that happens after customer conversations. Botpress and Chatbase need less setup than a full Voiceflow build.
Botpress is a visual chatbot builder for customer support teams. You build each bot on a drag-and-drop canvas called Botpress Studio, or you describe it in everyday language through the Viber builder. Finished bots run on web chat, WhatsApp, and Slack, and connect to helpdesks like Zendesk and Intercom.

I rebuilt a Voiceflow support bot in Botpress Studio to see how the move would feel for a team that already designs flows on a canvas. Each conversation step sat on one canvas, and I could test a reply in the side panel while I edited the card behind it. I rebuilt the order-status step by adding a short code card inside the flow and connecting it to a test order sheet inside the builder.
That mix of a visual canvas and room for code is the main point of difference in most Botpress vs Voiceflow comparisons. Designers and developers work in the same workspace, so a support lead can map the conversation while an engineer adds the custom logic behind it.
Non-developers face a steeper learning curve once a bot needs custom code or API calls. Self-hosting adds operations work, since your own team must install, update, and host the v12 edition. The Free plan limits you to 100 conversations with no top-ups, so production use requires a paid plan.
Botpress prices every plan per workspace, with no per-seat charge. The Free plan includes 100 conversations, 3 seats, and 3 bots each month. Plus is $189/month with 250 conversations and unlimited AI agents. Team is $939/month with 1,500 conversations and unlimited seats. Enterprise pricing is custom and adds dedicated support, an uptime SLA, and the voice channel.
Chatbase is a no-code chatbot builder that trains a bot on your own documents, web pages, and help content. You connect your data sources, write the bot's role and rules, and publish it to your website, WhatsApp, email, or Slack. Higher plans also add voice and telephony.

I connected a test help center to Chatbase, and a working bot answered questions on a sample website in the same session. The setup asked for three things: my data sources, a short description of the bot's role, and the rules it should follow. I didn't have to draw a flow, and I pasted the embed code onto the test page in one step.
The answers stayed close to the source content. When I asked about a return window, the bot quoted the policy from the help center and linked the exact article it used. For a support team that wants a document-trained bot to go live the same day, speed matters more than a detailed flow canvas.
Chatbase offers less conversation design control than Voiceflow because multi-step logic is written as text procedures, with no visual canvas to map the flow. Voice and telephony start on the Standard plan.
Hobby is $40/month with 700 message credits, 2 members, with access to advanced models and basic integrations. Standard is $150/month with 4,000 message credits, 3 members, voice, and telephony. Pro is $500/month with 15,000 message credits, 5 members, and advanced analytics. Enterprise pricing is custom. Every paid plan starts with a 7-day trial.
Lindy is an AI teammate that lives in your Slack and does real work for the whole team. It handles meeting follow-up, inbox triage, and CRM updates without requiring workflow setup. Every teammate gets a private Lindy in their DMs, and the team shares one in channels. When you @mention Lindy in a channel, it answers in the thread with sources from your meetings, tools, and files.

After a test sales call, I @mentioned Lindy in the deal channel and asked it to close out the meeting. Lindy pulled the notes from the recording, updated the HubSpot deal record, and wrote the handoff doc in Notion. It also drafted the follow-up email to the client and waited for my approval before sending anything.
The next morning, I asked Lindy in the same channel what the client had said about pricing on the call. The answer came back in the thread with a citation to the exact meeting, so I could check the source in one click.
Voiceflow bots are built to talk to customers. Lindy covers the internal work that follows those conversations, from CRM updates to meeting prep, inside the Slack threads where the team already talks. One admin installs it, and everyone else links with one tap.
Lindy is built for internal teamwork in Slack, so it is the wrong fit if you need a customer-facing chatbot on your website. Heavy tasks, such as research reports or dashboards, use more credits, and Lindy pauses when the workspace runs out.
Lindy bills every active user in a workspace. The Team plan starts at $49.99/user/month with 5,000 credits, and extra credits cost $10 per 1,000. Enterprise pricing is custom and includes HIPAA compliance, a signed BAA, SSO, SCIM, audit logs, shared usage with bonus credits, and dedicated support.
New users can start on the Free plan with $50 in credits for 7 days, no card needed. Teammates who join a paid workspace through Slack get a 7-day trial before their seat is billed.
If you need inbound or outbound AI voice agents, these three tools go deeper than Voiceflow's native voice features. Each one is built around the phone call, with phone-line connections, call testing, and controls for high call volume. Synthflow suits teams that want a no-code builder, Retell AI suits developer-led teams, and Bland AI suits large outbound campaigns.

Synthflow is a no-code voice AI platform that answers inbound calls and places outbound calls for sales and support teams. You design each call in a visual Flow Designer, test it with simulated calls, and launch it over a Twilio number or, on Enterprise, Synthflow's own telephony or your own carrier. The same platform also handles chat and SMS.

I started from Synthflow's appointment-booking template and connected a test Google Calendar before I wrote a single custom step. The template already covered the greeting, the questions about time and service, and the confirmation at the end. My changes came down to the business name, opening hours, and two fallback replies.
Before any real caller dialed in, I ran the agent through the Test Center. Synthflow placed simulated calls, checked each one against pass-or-fail goals such as accurate answers, and showed where the flow needed a clearer answer. You could retest every fix in the sandbox, and each version was saved, so you could restore an earlier build at any time.
Synthflow's native telephony and SIP connections to your own carrier come only with Enterprise, so teams on Pay as you go run calls through a Twilio number. It also gives developers less control over each part of the voice stack than API-first tools such as Retell AI do.
Synthflow lets you build and test an agent for free with its template library. After launch, calls and chats are billed on a pay-as-you-go basis, although Synthflow does not publish its per-minute rates. Enterprise pricing is custom and scoped based on call volume, concurrency, telephony, integrations, and launch support.
Retell AI is an API-first voice AI platform for teams that want to build phone agents with full developer control. Developers can work through Retell's APIs and SDKs, while support leads can edit the same agent on a drag-and-drop canvas. Each agent answers inbound calls, runs outbound campaigns, and can also work over chat and SMS.

I built a test receptionist on Retell's canvas and connected it to a calendar function, so the agent could check open slots during a live call. To compare models, I switched the agent from one large language model (LLM) to another in the same setting, and the call flow stayed intact. The test tools gave me the most confidence.
Retell handles voice at low latency, and its turn-taking model decides when the agent speaks and when it listens. You can check every change before a real caller hears it, which matters for a phone line customers depend on.
The same mix of control and testing explains why Retell appears in most Vapi AI alternatives roundups. Developers get APIs for every part of the platform, and the rest of the team still has a visual builder to work in.
Retell's deepest controls, such as custom LLMs, API-driven flows, and webhooks, need developer time to use well, so non-technical teams will use only part of the platform. Costs rise with call volume and model choice, and pay-as-you-go accounts receive only community and email support.
Retell charges per minute with no seat fees, and new accounts get $10 in free credits. Voice agents cost $0.07–$0.31/minute, depending on the model you choose. Enterprise pricing is custom.
Bland AI is a voice AI platform built for outbound call campaigns and high-volume phone work in regulated industries. It runs its own speech and language models on its own infrastructure, so call data does not pass through third-party model providers. Teams pay one per-minute rate for the model and voice, with no separate token charges. Telephony and call transfers are billed on top.

I asked Norm, Bland's build assistant, to create an appointment-reminder agent, and it drafted the call pathway, the calendar connection, and an SMS confirmation in response to a single request. I then ran the agent through Bland's test suite, which checked edge cases such as wrong numbers and callers who asked to reschedule, before any real call went out.
The test calls held their pace even when I interrupted the agent mid-sentence. Bland's own models keep latency low, and the agent stayed on script through every awkward reply I tried. For a team that plans to run thousands of outbound calls, that consistency matters more than any other feature.
Bland's Conversational Pathways builder has a steep learning curve, and complex enterprise agents usually take two to six weeks to deploy with help from Bland's engineers. The Start plan is capped at 100 calls per day, so the pricing makes the most sense for teams with steady, high call volume.
Bland's Start plan costs $0.14/minute with no platform fee and no card required. The Build plan costs $0.12/minute plus a $299/month platform fee and raises the limit to 50 concurrent calls. Enterprise pricing is custom.
Botpress and Rasa are the best free or open-source alternatives to Voiceflow. Both cost nothing to start, but the open-source versions run on your own servers, so your team handles hosting, updates, and security.
Botpress has a free cloud plan with 100 conversations/month. Its older v12 edition is also open source for teams that want to self-host.
Rasa is the code-first option. Its free Developer Edition runs on your own servers and supports one bot with up to 1,000 external conversations a month, and developers write each conversation flow as code. Rasa suits regulated teams that need full control over data, which is why it also appears in our Botpress alternatives roundup.

The right Voiceflow alternative depends on what you need to build and who will build it. Chat tools fit websites and support bots, voice tools fit phone calls, and Lindy fits internal teamwork. Your team's coding skills then narrow the choice to one tool.
Here is the clearest match for each situation:
Yes. Voiceflow is worth it for teams that design customer-facing chat and voice flows on a visual canvas. Its collaboration tools are used well by product, design, and CX teams. Voiceflow is less worth it for phone-first teams, where Retell AI is the better pick, or for internal Slack work, where Lindy is the better pick.
Yes, to start. Voiceflow's Free plan comes with a one-time credit grant that doesn't renew, so most production use needs a paid plan. For a free bot that goes live with real customers, Botpress is the stronger pick.
Botpress is the best free alternative to Voiceflow. Its free plan includes 100 conversations a month, 3 seats, and 3 bots, and chat flows are built on a drag-and-drop canvas much like Voiceflow's. Rasa is preferred by developers who want a free, self-hosted option. Chatbase suits no-code teams but offers only a 7-day trial.
Retell AI is the best Voiceflow alternative for voice AI. Phone agents can be built on a visual canvas or via APIs, and a GPT, Claude, or Gemini model can be selected for each agent. Every change can be tested against simulated calls before launch. Pricing starts at $0.07 per minute, with $10 in free credits for new accounts.
