Extension Availability for DuckDB Versions

Published

July 9, 2026

DuckDB extensions provide additional functionality but aren’t available for all versions and platforms. This webpage was created to simplify determining which extensions are available for specific versions of DuckDB, as tracking compatibility across different releases can be complex.

Here’s what affects extension availability:

Version Compatibility

Extensions are typically built for the current LTS (long term stable) (v1.4.x) release and the current DuckDB release (also 1.4.x but will soon be 1.5.x). However:

  • Legacy Extensions: Some extensions were released for older versions and haven’t been updated by their maintainers
  • New Extensions: Newer extensions may only be available for recent versions
  • Retired Extensions: Some extensions are no longer maintained or have been retired
  • Compatibility Updates Needed: Extensions may become incompatible with newer DuckDB versions and require maintainer updates

When upgrading DuckDB, check that required extensions are available for your target version.

Platform Support

Extensions are compiled for specific platforms. DuckDB supports:

Native Platforms:

  • linux_amd64_musl - Alpine/musl Linux x86_64
  • linux_amd64 - Standard Linux x86_64
  • linux_arm64 - Linux ARM64
  • osx_amd64 - macOS Intel
  • osx_arm64 - macOS Apple Silicon
  • windows_amd64_mingw - Windows x86_66 Mingw
  • windows_amd64 - Windows x86_64

WebAssembly:

  • wasm_mvp - Basic WASM
  • wasm_eh - WASM with exception handling
  • wasm_threads - WASM with threading

Extensions compiled for one platform won’t work on others. WebAssembly platforms typically have fewer available extensions due to browser environment limitations.

Why Extensions May Be Unavailable

  • Platform Dependencies: Extension requires libraries not available on all platforms
  • Compilation Issues: Technical challenges building for specific platforms
  • Maintenance: Extension no longer actively maintained for newer versions
  • Licensing: Distribution restrictions on certain platforms
  • Experimental Status: Only available in development builds

Best Practices

  • Verify extension availability before depending on it in production
  • Plan fallback strategies for critical functionality
  • Check compatibility when upgrading DuckDB versions
  • Monitor extension status between releases
