Install Nabla

Download signed binaries directly from our CDN and pin the exact version you want. Use the tabs to choose a platform and the dropdown to choose a version — the command updates automatically.

curl -fL https://cdn.usenabla.com/nabla-macos-arm64-v1.1.0/nabla -o nabla

Next steps

• Make the binary executable and place it on your PATH: chmod +x ./nabla && sudo mv ./nabla /usr/local/bin/
• Verify the install: nabla --version
• Checksums, signatures, and package managers will be documented here soon.

Verify signatures with Cosign

Nabla binaries are signed. A detached signature file nabla.sig is published alongside each binary. Verify the binary before installing.

1. Install Cosign

• macOS: brew install cosign
• Linux: use your package manager or see Sigstore docs.

2. Download signature and public key

Replace the platform and version to match what you downloaded from the tabs above.

# Example values — change to match your download
VERSION=v1.1.0
PLATFORM=nabla-macos-arm64   # or nabla-macos-amd64, nabla-linux-amd64
 
# Download the signature that sits next to the binary
curl -fL https://cdn.usenabla.com/${PLATFORM}-${VERSION}/nabla.sig -o nabla.sig
 
# Download the trusted Cosign public key
curl -fL https://cdn.usenabla.com/cosign.pub -o cosign.pub

3. Verify the signature

# Verify the downloaded binary using the detached signature and public key
cosign verify-blob \
  --key cosign.pub \
  --signature nabla.sig \
  nabla
 
# Expected: output indicates verification success

If verification fails, do not run the binary. Re‑download and re‑verify, or contact support.
