"Deployment Basics (4/7) — Free Hosting 1: Auto Deploying Frontends with Vercel"

Vercel feels easy not because deployment stops being complex, but because branch strategy and deployment strategy line up cleanly.

Key Takeaways

  • Vercel creates preview deployments for branch pushes and production deployments for the production branch when the repository is connected through Git.
  • As verified on 2026-05-18, the Vercel Hobby plan is free and aimed at personal and small-scale projects.
  • Vercel is especially strong for frontend and modern web framework workflows, but it is not the same thing as general long-running backend hosting.
  • The most important lesson is how Git branches map to preview and production environments.

1. Why Vercel works so well for beginners

Many beginners struggle less with server setup than with deployment flow itself. Which branch is safe? Where do you check a change before release? What is the difference between a review link and the production site?

Vercel makes those answers visible:

  • push a feature branch -> get a preview URL
  • review the result before merge
  • merge to the production branch -> get the production deployment

That turns Git structure into something you can literally open in a browser.

2. The basic deployment model

According to Vercel's Git deployment docs, the platform supports GitHub and other providers as direct deployment sources.

The common pattern is:

feature branch push
  -> preview deployment URL

main merge
  -> production deployment

That separation matters because it gives you a real environment to inspect before changing the live one.

3. What "free" means on Vercel

On 2026-05-18, Vercel's official pricing and Hobby plan docs describe Hobby as a free tier for personal projects, with included limits for compute, transfer, function invocations, and related resources.

The critical nuance is that free does not mean unlimited. Hobby is a good fit for portfolios, experiments, and small apps, but scale changes the decision quickly.

So the better question is not "is it free?" but "does my workload fit the free plan?"

4. Where Vercel is strongest

Vercel is a particularly good fit when:

  • the application is frontend-heavy
  • you want fast preview URLs for pull requests
  • your team reviews changes in a live environment
  • the framework already aligns well with Vercel's deployment model

It is a weaker fit when your main concern is long-running backend process management or deeper infrastructure control.

5. Common beginner mistakes

The first is assuming preview and production use the same environment variables. They do not have to.

The second is blaming the platform when local and cloud builds differ. In many cases the real cause is build commands, path-case mismatch, or runtime-version differences.

The third is expecting Vercel to behave like a full backend platform for every use case. It solves some problems beautifully, but not every hosting problem.

6. A simple operating rule set

If you are starting with Vercel, keep it simple:

  1. treat main as the production branch
  2. start all new work on feature branches
  3. review preview deployments before merge
  4. separate preview and production environment variables

Those four rules already give you a surprisingly strong release discipline.

"ML Foundations (9/9) — PyTorch vs TensorFlow, and the Road to Local LLMs"

← 8/9 Deep Learning Architec… ๐Ÿ“š Series Index (series end) The final part. So far we've focused on models. Now we focus on the tools that actually run them . We'll lay out the philosophical difference between PyTorch and TensorFlow, and trace how Hugging Face transformers , llama.cpp , MLX , and Ollama built the bridge to running large language models on your own machine. By the end you should have the full mental model of "download a pretrained LLM and serve it locally." 0. Learning Objectives Explain the eager-vs-graph difference between PyTorch and TensorFlow. Explain, in graph terms, how autograd automates the backward pass. Use Hugging Face transformers ' AutoModel , AutoTokenizer , and pipeline abstractions. Describe llama.cpp's GGUF quantization, INT4 inference, and CPU-first flow. Describe Apple MLX's use of unified memory and how it differs from PyTorch. Run a local LLM with Ollama and call it through an OpenAI-compatible API. ...

"RAG Core Study (14/26) — Evaluation Sets with RAGAS & DeepEval"

Series overview: Series index ๐Ÿ“š Series Index Without an evaluation set, every RAG improvement is a story, not evidence. RAG systems fail in more than one place: retrieval, context selection, answer generation, and grounding. That means "looks better" is not a metric. Part 14 explains how to build a golden dataset , how RAGAS and DeepEval fit into the workflow, and why teams must separate retrieval quality from answer quality if they want tuning decisions to hold up. 0. Prerequisites Part 13 reranking — system quality now depends on multi-stage ranking. Part 1 grounding — a correct-looking answer is not enough. Part 12 Hybrid — multiple retrieval settings need comparison on fixed data. 1. Learning Objectives Build a small but useful golden dataset for RAG. Distinguish retrieval metrics from answer metrics . Use RAGAS and DeepEval in the right roles. Avoid the common traps in judge-model-based evaluation. 2. ํ•ต์‹ฌ ์š”์•ฝ An evaluation set for RAG is ...
