In modern development, we’ve gotten used to something dangerous:
deployments we don’t understand.
Push code to GitHub, and—poof—it’s live. Platforms like Vercel and Netlify have set a gold
standard for Developer Experience (DX). But as projects scale and complexity grows, that
"magic" often turns into a frustrating "black box." When a build fails or a deployment behaves
unexpectedly, we find ourselves digging through proprietary logs, guessing at build
environments, and fighting "hidden" configurations.
We’re building Hostack to fix that.
Hostack is a "deploy-from-GitHub" platform that gives you the same "Push-to-Deploy" flow you
love, but with the engine hood wide open.
The Core Flow: Simplicity Meets Visibility
The Hostack lifecycle is intentionally straightforward:
Repo Hook: A GitHub Action or Webhook triggers on push.
Smart Detection: We scan your codebase to identify the framework (Next.js, Astro, Remix,
etc.).Job Queuing: A specialized worker is assigned to your build.
The "Transparent" Build: We build your app in an ephemeral, isolated environment.
Global Deployment: Your artifact is shipped to the edge or a container runtime.
The "How" Matters: Solving the Pain Points
While the flow is simple, the implementation is where it gets interesting. Here’s how we’re
tackling the biggest challenges in deployment orchestration:
- Framework Detection: The "Hybrid" Approach One of the biggest debates in building Hostack was how "smart" the platform should be. If we’re too magic (Pure Heuristics), we’re just another black box. If we’re too manual (Explicit Config), the DX suffers.
We chose the Hybrid Approach.
By default, Hostack scans your package.json and config files to "guess" the best build
command. But, every project can include a hostack.yaml. This file acts as your "Source of
Truth," allowing you to override any detected settings. Transparency means never having to
wonder why a certain build command was chosen.
- Worker Architecture: Clean-Room Isolation In a monorepo, dependencies can become a nightmare. How do you ensure the build for your React frontend doesn’t conflict with your Go-based API or your n8n automations?
Hostack uses Ephemeral Docker Workers. Instead of one massive worker with every runtime
installed, our orchestrator pulls a specific "Builder Image" based on your project type.
React? We spin up a node:20-alpine builder.
n8n? We spin up a specialized n8n-builder with the n8n-cli pre-installed.
This ensures your build environment is clean, reproducible, and—most importantly—auditable.
You can see exactly which image was used and even run it locally for debugging.
- n8n as a First-Class Citizen We believe automation should be treated like code. That’s why Hostack isn’t just for web apps. By integrating the ubie-oss/n8n-cli, Hostack allows you to manage your n8n workflows directly from your GitHub repo.
Using the --git-diff and --externalize flags, Hostack only deploys the workflows that have
changed and extracts complex JavaScript nodes into separate files for better PR reviews.
Automation is no longer a "side thing"—it's a core part of your deployment pipeline.
Where We’re Going
Hostack isn't just about deploying code; it's about giving developers the keys to their own
infrastructure. We’re currently exploring even more transparency features, like:
Raw Build Logs: Real-time, un-redacted streaming from the worker.
Dockerfile Export: Automatically generate the Dockerfile Hostack used to build your app so
you can take it anywhere.
PR-Specific Workflow Diffs: See exactly what logic changed in your n8n workflows before you
hit "Merge."
Join the Discussion
We’re building this in the open and we want your input. We’ve just started a discussion on our
GitHub about framework detection and worker separation.
