Session VPN on Lambda MicroVMs. MicroVM terminates when disconnected - zero cost. ~20s cold start. Exit from 5 AWS regions. $5/mo license + AWS compute.
Overview
Overview
Serverless VPN runs on AWS Lambda MicroVMs - Firecracker-based virtual machines that terminate when you disconnect, costing nothing until you reconnect. Your traffic exits from AWS IP addresses, giving you privacy without shared VPN servers.
Unlike traditional VPNs that charge monthly whether you use them or not, Serverless VPN costs $0 when disconnected. The MicroVM terminates - no compute, no storage, no ongoing charges. You pay only $5/mo software license plus your own AWS compute costs (~$0.13/hr when active).
Key Features
- Zero idle cost - MicroVM terminates when you disconnect. No compute, no storage, no charges until you reconnect.
- ~20-second cold start - fresh MicroVM launches from snapshot each session. No long provisioning wait.
- 5 AWS region exit points - choose where your traffic exits: US East, US West, Europe, or Tokyo.
- No shared infrastructure - your own dedicated MicroVM. No other users on your instance.
- Session-based privacy - 8-hour max sessions with automatic reconnect. Perfect for work hours.
- CloudTrail auditable - all MicroVM operations logged. Enterprise compliance friendly.
- One-command operation - ./vpn.sh start connects, ./vpn.sh stop terminates.
How It Works
- Subscribe and deploy the CloudFormation template in your AWS account
- Download vpn.sh and install wstunnel (one-time setup)
- Run ./vpn.sh start - all traffic now routes through AWS
- Run ./vpn.sh stop - back to your normal IP, MicroVM terminates ($0)
Architecture
Your Mac/Linux machine connects via WebSocket tunnel (wstunnel) to a SOCKS5 proxy (microsocks) running inside the Lambda MicroVM. The MicroVM has default internet egress - no VPC or NAT Gateway needed. All traffic is masked behind an AWS IP address.
Pricing
Software license: $5/month
AWS compute (paid to AWS, in your account):
- Active: ~$0.13/hr (2GB ARM MicroVM, per-second billing)
- Disconnected: $0 (MicroVM terminated, nothing running)
- Data transfer: $0.09/GB outbound
- Typical month (8hr/day): ~$23 AWS costs
Requirements
- AWS account with Lambda MicroVMs access (GA in us-east-1, us-east-2, us-west-2, eu-west-1, ap-northeast-1)
- AWS CLI v2.27+ (brew upgrade awscli)
- macOS or Linux (Windows via WSL2)
- wstunnel binary (install instructions provided)
Good to Know
- Session VPN, not 24/7 - designed for work sessions. 8-hour max per session.
- SOCKS5 proxy - routes TCP traffic (web, APIs). Does not tunnel UDP.
- Streaming services may block AWS IPs - Netflix, Disney+ detect cloud provider IPs.
- Runs on Graviton (ARM64) - Amazon Linux 2023.
