# streamlit-ace — Ace editor component for Streamlit.

License: permissive · Maintenance: abandoned · Downloads: 133.7K/mo

## What it is and what it does

Streamlit-ace wraps the Ace code editor as a Streamlit component, letting you drop an interactive code editor into a Streamlit web app. It depends only on streamlit itself and provides a single function, st_ace(), that spawns an editor and returns its contents as you type. The editor includes syntax highlighting and is useful when your app needs users to write or edit code directly in the browser.

The package is minimal and permissively licensed under MIT, making it easy to integrate into Streamlit dashboards and data apps. However, it has been abandoned since late 2021 with no recent updates, so compatibility with the latest Streamlit releases and modern Python versions is uncertain.

Use it for:

- Add a live code editor to a Streamlit data app where users can write Python or SQL queries.
- Build an interactive tutorial or documentation site that lets readers edit and run code snippets.
- Create a code review or snippet-sharing tool with syntax-highlighted input fields.
- Embed a configuration editor in a Streamlit admin dashboard for users to write YAML or JSON.
- Prototype a lightweight IDE or notebook-like interface for exploratory coding within Streamlit.

## Worth the install?

AI-flagged interpretation of the facts above — verify before relying.

Embeds an Ace code editor component into Streamlit applications, allowing users to edit and display code with syntax highlighting within a web app.

Yes, if you need an Ace editor in a Streamlit app and can tolerate the maintenance risk. The package is simple, has no complex dependencies, and carries no known vulnerabilities. However, verify compatibility with your Streamlit version first—the last release was 2021-12-07, and no updates are planned. Consider it a stable but unsupported tool; if you hit a breaking change, you may need to fork or switch to an alternative.

## Install

pip install streamlit-ace
uv add streamlit-ace
poetry add streamlit-ace

## Installing streamlit-ace

Before you install: Installation is straightforward with no compiled dependencies. However, the package is abandoned—last release was 2021-12-07, over 1711 days ago. No recent maintenance or bug fixes should be expected.

License in practice: MIT license permits use, modification, and distribution with minimal restrictions, suitable for both open-source and commercial projects.

Quickstart:

pip install streamlit-ace

import streamlit as st
from streamlit_ace import st_ace

content = st_ace()
st.write(content)

Verify before relying:

- Whether the package remains compatible with current Streamlit versions and modern Python environments.
- Whether the Ace editor component renders correctly in recent browser versions.
- Known issues or limitations not documented in the available description.
