streamlit-keyup
Text input that renders on keyup
Decision gist · record as of 2026-08-14
Yes, if you're building a Streamlit app and need keystroke-level responsiveness on text input. Install friction is minimal and maintenance is active. Verify the license terms in the repository first, since the package metadata does not declare one. No known security issues.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Low friction install with just two runtime dependencies (streamlit and jinja2).
- Actively maintained as of early 2025 with a modest but engaged user base.

What it is and what it does
streamlit-keyup wraps Streamlit's text input to fire updates on every keystroke rather than waiting for the user to finish and submit. It's a thin layer on top of streamlit and jinja2 that lets you react to text as it's being typed, useful for search-as-you-type, live validation, or instant filtering in a web app.
The package offers a function that mimics Streamlit's text input API but adds a debounce parameter to throttle how often updates fire. It's designed for developers already building Streamlit apps who need finer-grained control over text input timing without building custom JavaScript.
Use it for
- Search-as-you-type interfaces where results filter or update with each character typed.
- Live validation of user input (e.g., checking if a username is available in real time).
- Instant autocomplete or suggestion lists that respond to partial text entry.
- Debounced API calls triggered by user typing, to avoid overwhelming a backend with requests.
