What is pneumaticworkflow?
Pneumatic is a workflow management system that lets teams design, run, and optimize business processes through reusable templates. Users create workflow templates defining steps, assignees, deadlines, and conditional logic, then launch multiple workflow instances from each template. Each team member gets a personal task bucket to work through efficiently. The platform includes an AI-powered workflow builder that generates templates from natural language descriptions, shareable kick-off forms for external participants, guest performer access, urgent prioritization, workflow variables for data passing, video embeds in tasks, activity highlights, dashboards, comments with mentions, and a WYSIWYG editor. It runs via Docker Compose with PostgreSQL, Redis, RabbitMQ, and nginx, exposing ports 80, 443, and 8001. The self-hosted edition supports SSO via Okta or Auth0, OAuth via Google and Microsoft, and configurable email providers. A free cloud tier offers unlimited users and workflows; enterprise engagements add on-premise deployment, custom integrations, SLAs, private code branches, and dedicated support. Licensed Apache 2.0.

FAQ
How does human-in-the-loop work?
Workflows alternate between AI tasks (processing data, generating summaries, making recommendations) and human tasks (review, approve, escalate). Each step has full audit trail and conditional logic.
What AI models do you support?
Pneumatic integrates with any OpenAI-compatible API including local LLM deployments, Azure OpenAI, Anthropic, and other providers. Custom ML pipelines and internal AI services are also supported.
Do you support on-premise deployment?
Yes, Pneumatic can be deployed on your own servers, private cloud, or any infrastructure. The core engine is open source (Apache 2.0) so your team can audit the code before deployment.
Can I start with Free and upgrade to Enterprise later?
Yes, many customers start with Free to explore the platform, then engage the Enterprise team when ready for custom AI workflows or on-premise deployment. Data and workflows transfer seamlessly.
What's included in the Enterprise engagement?
A dedicated implementation team handles process discovery, workflow design, custom integrations, LLM connectivity, on-premise deployment, team training, and ongoing support. Typical go-live in 4-8 weeks.
Is the Free plan really free forever?
Yes, the Free plan has no time limits, no credit card required, and no per-user charges. Unlimited users and workflows on the managed cloud.
