Deployment Guide
Sendless is a self-hosted, serverless file transfer portal for organizations that can't hand their files to a third-party SaaS service. It runs entirely in your own AWS account: files are stored in an Amazon S3 bucket in the Region you choose, and nothing passes through us.
You deploy Sendless with one AWS CloudFormation template in about five minutes. There are no servers or containers to manage: Amazon CloudFront, AWS Lambda, Amazon DynamoDB, Amazon S3 and Amazon Cognito scale with use, and AWS bills the infrastructure directly to your account. Deleting the stack removes everything.
What this subscription includes
This listing is Sendless Pro. After subscribing, you receive a license key by email. One subscription covers as many installations as you like, for production, testing, other Regions or other teams. Paste the key into each installation under Admin > License to turn on:
- Single sign-on with SAML or OpenID Connect: Microsoft Entra ID, Okta, Google and more
- Malware scanning with Amazon GuardDuty Malware Protection for S3; downloads are blocked until files are clean
- Audit log of every upload, open, download and admin change, with CSV export
- Policies: mandatory passwords, maximum link lifetime, download limits, blocked file types, allowed recipient domains
- Branding: your name, logo, colors and texts
The license is checked offline. Sendless never contacts us and sends no telemetry.
In every installation
- Large files: resumable multipart uploads straight to S3, up to 5 TB per file
- Links that expire after a time or a number of downloads, with optional passwords and lockout
- File requests: customers and partners upload files to you without an account
- Email delivery of links and notifications through Amazon SES
- Activity log per transfer, with IP address and country
- User management, self sign-up for your email domains, two-factor authentication
- Guaranteed deletion: a cleanup job every 15 minutes plus an S3 lifecycle rule as a hard limit
- Your own domain, English and German, light and dark theme
Security
- Data stays in your account and Region; no Lambda@Edge
- The API can only be reached through your CloudFront distribution
- Encryption at rest, TLS everywhere and a strict content security policy
- Verifiable releases: the template pins SHA-256 checksums of the code it installs
How it works
- Subscribe and register to receive your Sendless Pro license key by email.
- Launch the CloudFormation template from https://sendless.cloud in the Region of your choice.
- Sign in as administrator, paste the license key under Admin > License and invite your team.
Sendless has an open-source core under the Apache-2.0 license. The documentation is at https://sendless.cloud/docs/ and the source code at https://github.com/silverlining-cloud/sendless .
Highlights
- Runs entirely in your own AWS account: files stay in your S3 bucket in the Region you choose, with no third party in between and no telemetry.
- One-click CloudFormation deployment, fully serverless: no servers to patch, close to no cost when idle, and deleting the stack removes everything.
- Sendless Pro adds single sign-on (SAML, OIDC), GuardDuty malware scanning, an exportable audit log, policies and branding, for unlimited installations.

Dimensions summary
This listing offers one contract option: Sendless Pro for 12 months. You buy a single license key that activates Pro features across unlimited installations in as many of your AWS accounts and hosts as you want. Pricing does not scale by number of installations or users. The license covers single sign-on, malware scanning, an audit log with CSV export, policies, and branding. You still pay AWS directly for the infrastructure each installation uses, such as storage and data transfer, which is billed separately from this license.
Top-of-mind questions for buyers
The key unlocks Pro features such as single sign-on, malware scanning, the audit log, policies and branding. You paste it under Admin → License, and it is checked offline without contacting the vendor. One key works across every installation you run in your AWS accounts.
The infrastructure is billed separately. AWS charges your own account for what each installation uses, mainly S3 storage and data transfer out when people download files, plus smaller amounts for Lambda, DynamoDB, CloudFront and Cognito. Malware scanning adds GuardDuty charges per GB scanned. An idle installation costs close to nothing.
Pro features keep working for 14 more days after expiry. After that, they turn off, but nothing is deleted. Your files, users and settings stay in place, and the free Community features continue to run from the same template.
