StackForDev
CLI tool and web app that generates tailored Dockerfiles so developers only need Docker, with no language runtimes to install locally.
01 Overview
StackForDev solves the "works on my machine" problem by replacing dozens of language and framework installations with a single prerequisite: Docker.
You tell StackForDev your language, stack, and version. It generates a Dockerfile that turns any directory into a fully configured development container. Your project files are volume-mounted inside, so there is nothing to install locally beyond Docker itself.
The backend is a Python service running on AWS Lambda, distributed as a container image via ECR. AWS API Gateway sits in front with per-IP rate limiting and a monthly quota to keep costs predictable. Generated Dockerfiles are stored in S3 with content-based deduplication so identical requests return a cached file instantly.
The CLI is published on PyPI as `stackfordev`. It supports interactive prompts for discoverability and non-interactive flags for scripting. A `--local` flag generates Dockerfiles offline without any API calls.
The web UI is built with SvelteKit and offers the same language / stack / version picker in the browser, with a live Dockerfile preview and copy-to-clipboard. An Info page lists every supported language, version, and stack combination.
The entire infrastructure (Lambda, API Gateway, S3, ECR, CloudWatch alarms, and IAM roles) is managed with Terraform Cloud backed by GitHub.
02 Key Features
03 Architecture
System Architecture
The SvelteKit frontend is deployed as a static site. The CLI and browser both hit the same AWS API Gateway endpoint, which invokes a containerised Lambda function. Generated Dockerfiles are stored in S3 with SHA-256 content deduplication.
Dockerfile Generation Flow
Each request is validated by Pydantic, checked for injection patterns, resolved to a language template, then stored in S3 with a content-based key before the Dockerfile is returned.
Infrastructure as Code
All AWS resources are provisioned with Terraform Cloud. GitHub pushes trigger plan/apply runs. Reserved Lambda concurrency caps cost; lifecycle policies on S3 and ECR manage storage.
