Easy and fast file sharing from the command-line. This code contains the server with everything you need to create your own instance. currently supports the s3 (Amazon S3), gdrive (Google Drive) providers, and local file system (local).


This project repository has no relation with the service at that's managed by So far we cannot address any issue related to the service at



$ curl --upload-file ./hello.txt

Encrypt & upload:

$ cat /tmp/hello.txt|gpg -ac -o-|curl -X PUT --upload-file "-"

Download & decrypt:

$ curl|gpg -o- > /tmp/hello.txt

Upload to virustotal:

$ curl -X PUT --upload-file nhgbhhj


$ curl -X DELETE <X-Url-Delete Response Header URL>

Request Headers


$ curl --upload-file ./hello.txt -H "Max-Downloads: 1" # Limit the number of downloads


$ curl --upload-file ./hello.txt -H "Max-Days: 1" # Set the number of days before deletion

Response Headers


The URL used to request the deletion of a file. Returned as a response header.

curl -sD - --upload-file ./hello | grep 'X-Url-Delete'

Parameter Description Value Env
listener port to use for http (:80)
profile-listener port to use for profiler (:6060)
force-https redirect to https false
tls-listener port to use for https (:443)
tls-listener-only flag to enable tls listener only
tls-cert-file path to tls certificate
tls-private-key path to tls private key
http-auth-user user for basic http auth on upload
http-auth-pass pass for basic http auth on upload
ip-whitelist comma separated list of ips allowed to connect to the service
ip-blacklist comma separated list of ips not allowed to connect to the service
temp-path path to temp folder system temp
web-path path to static web files (for development or custom front end)
proxy-path path prefix when service is run behind a proxy
ga-key google analytics key for the front end
uservoice-key user voice key for the front end
provider which storage provider to use (s3, gdrive or local)
aws-access-key aws access key AWS_ACCESS_KEY
aws-secret-key aws access key AWS_SECRET_KEY
bucket aws bucket BUCKET
s3-endpoint Custom S3 endpoint.
s3-region region of the s3 bucket eu-west-1 S3_REGION
s3-no-multipart disables s3 multipart upload false
s3-path-style Forces path style URLs, required for Minio. false
basedir path storage for local/gdrive provider
gdrive-client-json-filepath path to oauth client json config for gdrive provider
gdrive-local-config-path path to store local config cache for gdrive provider
gdrive-chunk-size chunk size for gdrive upload in megabytes, must be lower than available memory (8 MB)
lets-encrypt-hosts hosts to use for lets encrypt certificates (comma seperated)
log path to log file

If you want to use TLS using lets encrypt certificates, set lets-encrypt-hosts to your domain, set tls-listener to :443 and enable force-https.

If you want to use TLS using your own certificates, set tls-listener to :443, force-https, tls-cert=file and tls-private-key.


Switched to GO111MODULE

go run main.go --provider=local --listener :8080 --temp-path=/tmp/ --basedir=/tmp/


If on go < 1.11

go get -u -v ./...
go build -o transfersh main.go


For easy deployment, we've created a Docker container.

docker run --publish 8080:8080 dutchcoders/ --provider local --basedir /tmp/

S3 Usage

For the usage with a AWS S3 Bucket, you just need to specify the following options:

  • provider
  • aws-access-key
  • aws-secret-key
  • bucket
  • s3-region

If you specify the s3-region, you don't need to set the endpoint URL since the correct endpoint will used automatically.

Custom S3 providers

To use a custom non-AWS S3 provider, you need to specify the endpoint as definied from your cloud provider.

Google Drive Usage

For the usage with Google drive, you need to specify the following options:

  • provider
  • gdrive-client-json-filepath
  • gdrive-local-config-path
  • basedir

Creating Gdrive Client Json

You need to create a Oauth Client id from download the file and place into a safe directory

Usage example

go run main.go --provider gdrive --basedir /tmp/ --gdrive-client-json-filepath /[credential_dir] --gdrive-local-config-path [directory_to_save_config]
