Secure File Transfer in Your Own AWS Account.
Secure file transfer for teams that cannot use SaaS file sharing.
Sendless sends large files with expiring, password-protected links and collects files from anyone, with no third party in between. It deploys into your own AWS account with one click and runs entirely on native AWS services, so your files never leave your account. The Community edition is free and open source; Sendless Pro adds single sign-on, malware scanning, an audit log, policies and your own branding.
Deploy directly into your AWS account.

❓Why Sendless
Many organizations are not allowed to use external file sharing services such as WeTransfer, Dropbox or Google Drive because of internal policies or regulatory requirements.

- Billing

- Links that expire after a time or a number of downloads, or when you revoke them
- Optional passwords for links, checked on the server with a lockout
- File requests: customers and partners upload files to you without an account
- Email links to recipients and get notified when a link is opened
- Activity log for every transfer
- User management, self sign-up for your email domains and two-factor authentication

Frequently Asked Questions (FAQ)
Does Sendless run as a SaaS?
No. Sendless runs entirely in your AWS account. After deployment, all components are owned and managed by you.
Where are files stored?
In an Amazon S3 bucket in your own AWS account, in the Region you choose.
Does any data leave my AWS account?
No. Files go straight from the browser to your S3 bucket and back. There is no telemetry, and Pro license keys are checked offline.
Can I use my own domain?
Yes. Enter a name such as files.example.com and a certificate from AWS Certificate Manager when you launch the stack, then point a CNAME record to CloudFront.
Is this suitable for regulated environments?
Yes. Sendless is designed for environments with strict security, compliance or audit requirements. Sendless Pro adds single sign-on, malware scanning, an audit log and policies.
Can I remove the solution later?
Yes. Delete the CloudFormation stack. Sendless empties its buckets first, so nothing is left behind in your account.
What is the difference between Community and Pro?
Both editions run from the same template. Community is free and open source. A Pro license key adds single sign-on, malware scanning, the audit log, policies and your own branding, without reinstalling.
How many installations does one Pro license cover?
As many as you like: production, testing, other Regions or other teams, all for USD 1,399 per year.
