A thread-safe progress bar library for Go applications that works across all operating systems. It supports io.Writer integration for automatic byte counting, spinners for unknown-length tasks, and extensive customization of themes, colors, and output.
Use cases
- show a progress bar for a long-running loop in a Go CLI
- display download progress while copying an HTTP response body to a file
- show a spinner for tasks with unknown duration
- wrap io.Reader/io.Writer streams to track bytes processed
- customize progress bar colors, width, and theme in a terminal app
When to choose
- you need a simple, dependency-light, thread-safe progress bar in Go
- you want automatic progress tracking for io.Copy and streaming operations
- cross-platform terminal compatibility matters and you only need single-line output
When to avoid
- you need multi-line or dashboard-style terminal output
- your project is not written in Go
- you need rich TUI widgets beyond a single progress bar
