Just published my first four custom Streamlit components!
Hey everyone — I’ve been building with Streamlit for a while and finally got around to packaging some components I kept wishing existed. All four use React 18 + streamlit-component-lib, ship with pre-built frontends (no Node.js needed), and return structured JSON back to Python on every interaction.
Would love bug reports, feature requests, or just to hear if you find them useful.
streamlit-kanban — Drag-and-drop Kanban board
Move cards between columns, add/edit cards with tags and priority levels, get the full board state back as JSON. Uses pointer events so drag works smoothly inside Streamlit’s iframe.
pip install streamlit-kanban

streamlit-audio-editor — Browser-based audio editor & jam session recorder
Load any audio file, visualize the waveform, trim it, and run it through a real-time effects rack: 3-band EQ, LP/HP/BP/notch filter, compressor, delay, chorus, distortion, tremolo, reverb, stereo pan, speed/pitch control. You can also route your mic through the chain and record your session. All client-side via Web Audio API — no ffmpeg needed.
pip install streamlit-audio-editor

streamlit-stepper — Multi-step wizard with validation
Define steps with typed fields (text, textarea, select), built-in required-field validation, animated progress connectors, and an auto-generated review step. Collected values come back in Python. Supports horizontal and vertical orientations.
pip install streamlit-stepper

streamlit-node-editor — Node graph editor (ComfyUI-style)
Define typed node definitions in Python, let users build graphs by dragging and connecting ports. Color-coded typed ports, inline parameters (dropdowns, numbers, text), searchable node palette, collapsible nodes, pan + scroll-to-zoom, animated dot-grid background.
pip install streamlit-node-editor

Early releases, actively iterating — all feedback welcome. Thanks for checking them out!
