Dead-simple file sharing for developers and AI agents.
Upload with one command. Share with a link. No account required.

$ tf upload model.gguf
✓ Uploaded  model.gguf  (4.2 GB)  →  https://transfa.sh/f/xK9mRp
  SHA-256    a3f8c2...d91b

Why transfa?

Most file-sharing tools are built for humans clicking through UIs. transfa is built for the terminal — designed to be called from shell scripts, CI pipelines, and AI agents (Claude, GPT, Cursor, etc.) that need to move files without friction.

• No signup required — just install and upload
• Any format, any size — up to 100 GB; ML models, archives, binaries, code, media
• Built for agents — JSON API, SHA-256 checksums, idempotent uploads
• Password protection, download limits, TTL — full control over every link
• 100+ formats detected — MIME type auto-detection including .gguf, .safetensors, .parquet, .ipynb, and more

Install

Node.js / CLI

npm install -g transfa

Python SDK

pip install transfa

MCP server (Claude, Cursor, any MCP-compatible agent)

npx -y transfa-mcp

Or use the raw install script:

curl -fsSL https://transfa.sh/install | sh

Quick start

# Upload a file (no account needed)
tf upload photo.jpg

# Upload with custom TTL and password
tf upload secret.zip --ttl 24h --password hunter2

# Upload and pipe the URL to clipboard
tf upload bundle.tar.gz | grep url | awk '{print $2}' | pbcopy

# Download a file
tf download https://transfa.sh/f/xK9mRp

# List your uploads
tf list

# Delete an upload
tf delete xK9mRp

GitHub Actions

Upload build artifacts, coverage reports, and any CI output straight from your workflow:

- uses: colapsis/transfa-action@v1
  id: upload
  with:
    file: ./dist/report.pdf
    api-key: ${{ secrets.TRANSFA_API_KEY }}

- run: echo "${{ steps.upload.outputs.agent-link }}" >> $GITHUB_STEP_SUMMARY

All five outputs are available after the step: id, agent-link, human-link, sha256, expires-at.

See colapsis/transfa-action for the full input reference and more examples (password-protected links, self-hosted instances, single-download limits).

API

transfa is fully REST. Every operation the CLI does, you can do with curl or any HTTP client.

curl -X POST https://transfa.sh/api/upload \
  -H "Authorization: Bearer $TF_KEY" \
  -F "file=@model.gguf" \
  -F "ttl=7d"
