JustFlows
JustFlows is a fully-featured PHP platform that allows you to start your own AI-powered workflow automation SaaS in no time.
Version 1.0.0 (Updated Aug 30, 2026)
Build flows visually with reusable AI steps, conditions, actions, approval gates, and mapped outputs, then test and publish them with confidence.
Describe what you want to automate, and Flowy can draft workflows, explain steps, suggest fixes, and help connect the right tools.
Create reusable agents with provider accounts, model settings, prompts, skills, attached knowledge bases, MCP servers, and tools that can be dropped into workflow steps.
Bring your own model accounts into the workspace and choose the right provider for each agent, workflow, and operating cost.
Organize flows, integrations, AI accounts, members, invitations, and operational activity around each workspace so teams can keep automation scoped and auditable.
Keep automation useful without making it reckless: route low-confidence or sensitive steps into approval queues, track executions, and inspect runtime logs.
Connect workflows to app events, webhooks, external services, MCP capabilities, and custom tool definitions so agents can do useful work inside the systems teams already use.
Round out the launch with the platform essentials that make a workflow SaaS easier to operate, customize, and grow.
Get the source code, keep control of your data, and launch on your own infrastructure without recurring platform fees.
