Up
Deploy serverless apps to AWS Lambda in seconds
Up deploys HTTP servers, APIs, and static sites to AWS Lambda with zero infrastructure management. Use existing frameworks—no new code required.
Overview
Self-Hosted Serverless Deployment
Up delivers a Heroku-like deployment experience on AWS infrastructure, eliminating the complexity of managing servers, scaling, logging, and monitoring. Deploy production-ready applications to AWS Lambda and API Gateway in seconds using a single command.
Framework-Agnostic Architecture
Unlike proprietary serverless platforms, Up works with standard HTTP servers—Express, Koa, Django, Flask, Go net/http, and more. Support for Node.js, Go, Python, Java, Crystal, Clojure, and static sites means you can deploy existing applications without refactoring. The platform-agnostic design focuses on vanilla HTTP, so your code remains portable and framework knowledge transfers directly.
Cost-Effective Scalability
Leveraging AWS Lambda's pay-per-execution model, Up enables you to deploy dozens of applications for pennies while automatically scaling to handle any traffic volume. The open-source edition provides core deployment capabilities, while Up Pro ($19.99/month) adds production features including encrypted environment variables, error alerting, unlimited applications and team members, priority support, and global deployments—all without per-app or per-seat fees.
Highlights
Deploy vanilla HTTP servers with existing frameworks—no code changes required
Single-command deployment to AWS Lambda and API Gateway infrastructure
Built-in logging, monitoring, and alerting without additional configuration
Flat-rate Pro pricing covers unlimited apps and team members
Pros
- Works with existing HTTP frameworks and codebases without modification
- Eliminates server management and auto-scales with AWS Lambda
- Cost-effective: pay only for execution time, not idle servers
- MIT licensed open-source core with affordable Pro tier
Considerations
- AWS-only deployment target limits multi-cloud flexibility
- Lambda cold starts may impact latency for infrequent requests
- Production features like encrypted variables require Pro subscription
- Requires AWS account configuration and credential management

Fit guide
Great for
- Teams wanting Heroku simplicity with AWS cost efficiency and control
- Deploying multiple microservices or APIs without per-app pricing
- Developers familiar with traditional HTTP frameworks seeking serverless benefits
- Startups needing auto-scaling infrastructure without DevOps overhead
Not ideal when
- Applications requiring sub-50ms response times or stateful connections
- Teams committed to multi-cloud or non-AWS infrastructure strategies
- Workloads with sustained high traffic where dedicated servers cost less
- Projects needing real-time WebSocket or long-running background jobs
How teams use it
Microservices API Deployment
Deploy dozens of independent API services with automatic scaling and pay-per-request pricing instead of maintaining dedicated Kubernetes clusters
Staging Environment Provisioning
Spin up isolated staging environments for each feature branch in seconds without paying for idle infrastructure between tests
Static Site Hosting with APIs
Deploy marketing sites alongside serverless backend APIs using a single tool and unified deployment workflow
Prototype and MVP Launches
Ship production-ready prototypes with enterprise-grade infrastructure, logging, and monitoring without upfront DevOps investment

Frequently asked questions
Do I need to rewrite my application to use Up?
No. Up deploys standard HTTP servers built with Express, Django, Flask, Go net/http, or any framework that listens on a port. Your existing code works without modification.
What's the difference between the open-source and Pro versions?
The OSS edition provides core deployment functionality. Up Pro ($19.99/month) adds encrypted environment variables, error alerting, unlimited applications and team members, priority support, and global deployments.
How does pricing compare to traditional hosting?
AWS Lambda charges only for execution time, not idle servers. You can deploy multiple applications for pennies per month with automatic scaling, versus paying for always-on instances.
Which cloud providers does Up support?
Up currently targets AWS Lambda and API Gateway. The platform is designed to be platform-agnostic, with AWS as the first supported infrastructure provider.
What languages and frameworks are supported?
Up supports Node.js, Go, Python, Java, Crystal, Clojure, and static sites out of the box. Any framework that creates an HTTP server works—Express, Koa, Django, Flask, and others.
