AI Agent Builders: quick answers, verified

Short, dated answers to the questions people ask about the software DDR reviews. Each one is verified on the vendor's own page and links to the full review for the detail.

Is Botpress free?
Yes, with a hard cap. The Free plan includes 25 conversations a month, 3 seats, and 3 AI agents, with no top-ups or overages, on the same isolated per-agent runtime as the paid tiers. Botpress moved to conversation-based pricing in September 2026: Plus is $150 a month billed annually (250 conversations) and Team is $750 a month billed annually (1,500 conversations, unlimited seats). Monthly billing runs about 20% higher. Verified on botpress.com/pricing, September 22, 2026.
Is Botpress HIPAA compliant?
Yes, on the Enterprise plan. Botpress lists HIPAA compliance and a formal Business Associate Agreement (BAA) as Enterprise features, alongside SOC 2 Type II certification, GDPR compliance, a private LLM gateway that strips PII before any model call, and zero data retention on the model provider's side. The Free, Plus, and Team plans do not include a BAA. Verified on botpress.com/enterprise and botpress.com/pricing, September 29, 2026.
Is Chatbase free?
Yes, with two limits that matter. The Free plan includes 50 message credits a month, one AI agent, one member, and limited model access, and agents on it are deleted after 14 days of inactivity. Paid plans are Hobby ($40/mo, 700 credits), Standard ($150/mo, 4,000), and Pro ($500/mo, 15,000), with 20% off on yearly billing. Verified on chatbase.co/pricing, September 29, 2026.
Is Dify free?
Yes, in two different ways. The self-hosted Community Edition is free with no license fee and no usage meter; you run it on your own infrastructure. The cloud Sandbox tier is also free, with 200 one-time message credits, one member, and five apps, and is meant for trying the hosted product. Paid cloud plans are Professional ($59/mo, or $590/yr) and Team ($159/mo, or $1,590/yr). Verified on dify.ai/pricing, September 22, 2026.
Is Gumloop free?
No. Gumloop has no permanent free tier. Its self-serve plan, Pro, starts at $37 a month with a 14-day free trial, and includes 20,000 credits, unlimited seats, teams, and agents, plus an 8% orchestration fee on credit usage. Enterprise is custom-priced. Older articles describing a free plan and a $97 Starter tier are out of date. Verified on gumloop.com/pricing, September 22, 2026.
Is Lindy AI free?
No. Lindy has no free tier. Its entry plan, Plus, is $29.99 per user a month with 3,000 credits, up to five inboxes, and Slack-native use; Pro is $99.99 (15,000 credits, computer use) and Max is $199.99 (35,000 credits). A 7-day free trial applies to teammates who join through Slack; direct sign-ups are billed from day one. Verified on lindy.ai/pricing, September 22, 2026.
Is MindStudio free?
Yes. MindStudio's free tier includes one agent and 1,000 runs, with access to the integration library. The Individual plan is $20 a month, or $16 a month billed yearly, with unlimited agents and runs; AI model usage is billed at cost on top of the plan, with no markup. Business is custom-priced. Verified on mindstudio.ai/pricing, September 22, 2026.
Is Voiceflow free?
Not for businesses. Voiceflow's public pricing page offers two tracks: agencies and partners get a free trial with no credit card, which converts to usage-based billing, and businesses are routed to a demo. No plan is priced on the page, and there is no free tier for a business account. Verified on voiceflow.com/pricing, September 22, 2026.
