FLOW-LIKE: ONE PLATFORM FOR DATA, AI, AUTOMATION, AND APPS Flow-Like brings data, AI, automation, and apps into one open-source, local-first platform. Build workflows, agents, dashboards, data pipelines, and complete applications in one governed projectβ€”then run them on your iPhone or iPad, even offline. BUILD THE WHOLE APP Start with a visual workflow, then add forms, calendars, Gantt plans, dashboards, diff views, voice experiences, and other interactive pages. User actions connect directly to your workflow logic, so the automation and the app around it stay together. Group related apps into Suites and let them cooperate through explicit permissions. BUILD VISUALLY OR AS CODE Drag and drop typed nodes for triggers, actions, conditions, AI, data, and media. Connections are checked as you build. Prefer code? FlowScript turns the same graph into readable, TypeScript-flavored source with completions, diagnostics, and safe round-tripping back to the canvas. Developers can create custom nodes with Rust or sandboxed WebAssembly. BUILD FASTER WITH FLOWPILOT FlowPilot is a platform-wide AI assistant that understands your apps. Ask it to create pages, draft or refactor workflows, work with data, explain logic, and call connected apps. Specialized assistants handle interface, workflow, and Data Studio tasks. Proposed changes stay reviewable, while optional profile-scoped memory preserves helpful context. RUN LOCALLY AND OFFLINE Flow-Like’s Rust engine executes natively on your device. Projects and local data stay under your control, and core workflows need no internet connection. Use supported local AI models and storage for private, offline work; sync or connect cloud services only when you choose. LOCAL AI AND MEDIA Build multimodal apps that work with text, images, audio, video, and documents. Transcribe speech, synthesize voice, analyze images and faces, and create video pipelines with native tools for transforms, thumbnails, subtitles, audio analysis, HLS, and more. UNDERSTAND YOUR DATA Data Studio brings databases, ontologies, graph relationships, queries, and analytics into the same workspace. Strong types and lineage track where data came from, how it changed, and which app or workflow used it. CONNECT WITHOUT LOSING CONTROL Connect Microsoft Office, Google Workspace, GitHub, Notion, Atlassian, and more. Apps expose only approved events and data to one another. Collaborate with live cursors and sync. Role-based access, version history, audit trails, process lineage, and retention controls keep work explainable across teams. FAST FROM PHONE TO SERVER The same Rust runtime scales from mobile devices to production infrastructure. Internal server benchmarks reach 244,000 events per second, with deterministic performance and no garbage-collector pauses. PRIVACY FIRST The core platform has zero telemetry. Your local workflows and data stay local unless you choose to sync them or use a connected service. Flow-Like is built in Germany and can be self-hosted for full infrastructure control.
