Wasmtime: 40.0.1
Build Timestamp: 2026-01-21T01:05:14+00:00

WASM Binaries

We build the following targets:

  • example_add_one: "add one" Rust example UDF
  • datafusion_udf_wasm_python: Guest for Python-based UDFs, bundles CPython.

Each of them is provided in debug and release builds. The artifacts have the file extension .wasm.

Machine-Code Binaries

In addition to the WASM binary blobs, we also provide pre-compiled guests for various targets to be used with wasmtime. The artifacts have the file extension .elf.

⚠️ Using pre-build binaries requires you to validate the source and trust the binary. Using a binary blindly can lead to remote code execution, memory and data corruption, and all kinds of bad things. You can use the provided build attestation. ⚠️

Checksums & Attestation

We provide sha256 checksums for all artifacts in sha256sum.txt. You can use that file -- either directly or indirectly via its own checksum -- to safely pin all artifacts of this release. We also provide build attestation.
