In their own words
Dify
Dify is an open-source platform for building AI applications with agentic workflows, retrieval pipelines, model management, observability, and tools. Workflow Studio provides a visual canvas for model calls, knowledge retrieval, tools, code, branching, triggers, and human review. Workflows can start from user input, API calls, schedules, webhooks, plugin events, or uploaded payloads. Knowledge Pipeline turns files, online documents, drives, crawlers, and web content into searchable knowledge bases with metadata and citations. Retrieval supports semantic, keyword, hybrid, and reranked methods with metadata filters. Applications can be published as hosted web apps, website embeds, API endpoints, or MCP servers. Dify connects to providers including OpenAI, Anthropic, Google Gemini, and xAI, while its Marketplace lists more than 200 tools. Community Edition is self-hostable with Docker; Enterprise can run in a customer VPC, on-premises, or an air-gapped network. Sandbox and Community are free. Professional costs $590 a year per workspace; Team costs $1,590 a year per workspace.
Voiceflow
Voiceflow is a platform for building, testing, deploying, and monitoring chat and voice agents across channels and languages. Its builder combines agentic playbooks, deterministic workflows, shared instructions, and guardrails. Teams can review transcripts and call recordings, run evaluations and tests, and track analytics. Agents can reach users through a native chat widget, mobile apps, phone calls, SMS, or custom interfaces built with the Conversations API. Native integrations include Zendesk, Salesforce, HubSpot, Shopify, Airtable, Google Sheets, Gmail, and Twilio. Agents can also connect to external REST APIs, custom Functions, and MCP servers. Teams can choose from major LLM providers or bring their own model. Voiceflow says customer data is not used to train AI or machine-learning models and integrated model providers are configured for zero data retention. Its security information describes encryption at rest with customer-managed keys and encryption in transit using TLS and mTLS. The company was founded in 2019. Agencies and partners have a free-trial plan with usage-based billing; business pricing is available on request. Support includes implementation that can be self-serve or fully managed.
