Introduction Recently, I have started to build apps using the web stack: frontend

htmx
tailwindcss

daisyui


alpine


backend

go

templ


postgres


devex

gitlab ci
nix devshells frontend

htmx
tailwindcss

daisyui

gitlab ci
nix devshells gitlab ci
nix devshells gitlab ci nix devshells I have now built two apps using this stack, one of them being banterbus.games a browser-based party game (currently broken). Using web sockets, so it isn’t the most normal web application. As there are a few quirks of web sockets. banterbus.games Banter Bus Code: https://gitlab.com/hmajid2301/banterbus https://gitlab.com/hmajid2301/banterbus I am currently building a more normal CRUD app, called Voxicle (https://voxicle.app), a SaaS platform for collecting and acting on user feedback. The first time, I am trying to build something which I will charge others for (hence the code also not being open-source yet). Some more context here: https://haseebmajid.dev/posts/2025-03-03-go-feedback-my-new-side-project/ https://voxicle.app https://haseebmajid.dev/posts/2025-03-03-go-feedback-my-new-side-project/ In this article, go over why I like this tech stack so much. Mainly because I want to keep things as simple as possible. One other thing to note, I am a backend developer, and don’t really like writing frontend code a la JavaScript (JS). So this stack is designed to avoid writing as many JS as I can, which other developers of course love writing. So read this article through those lenses. This stack might not make sense for you. Frontend One of the issues I found in my side projects was that I would always lose motivation when I had to write frontend code. For a few reasons, I never had enough experience with frameworks like React or Svelte to know how to structure them. Therefore, they would quickly become a mess. Another issue is maintaining consistent state between the backend and frontend. If we drive everything from the backend we can maintain most of our state there. Which works pretty well for a simple CRUD app we are building? The UI doesn’t need to do anything super crazy or clever. TailwindCSS For styling, I have stuck with TailwindCSS for a number of years, some people hate it. I have never minded it. It does lead to bloated class and makes the HTML look more complicated. But I never worked out how to structure CSS. So tailwind always felt simpler to me. I probably have a bunch of duplicated styles and can simplify what I have, as again I am no CSS expert nor frontend expert. But we can look at that if we feel the frontend is slow to load etc. DaisyUI I am using this component library on top of TailwindCSS, which provides us with a bunch of components and themes we can use out of the box. Straightforward to style and tweak/change. I like it again, backend developer doing frontend so perhaps for more complicated apps, you want your own design system and creating your own components is better. But again, I really like how easy it makes frontend development feel for me. HTMX The frontend is built using HTMX, as a simple library, where we drive most of our state from the backend. The server returns HTML (vs JSON) and then we tell it where to replace. Look at this HTMX request. When the form is submitted, we send a POST request to the /feedback endpoint the body is the input fields as JSON. (json-enc extension converts it to JSON for us). Then the target means the HTML returned replaces the outer HTML feedback_list /feedback json-enc feedback_list <form
    hx-post="/feedback"
    hx-target="#feedback_list"
    hx-swap="outerHTML"
    hx-ext="json-enc"
    class="space-y-6"
> <form
    hx-post="/feedback"
    hx-target="#feedback_list"
    hx-swap="outerHTML"
    hx-ext="json-enc"
    class="space-y-6"
> AlpineJS I combined HTMX with AlpineJS, as some actions you don’t always want to go to the server. Like opening a modal, or accordion. I don’t use it a lot and maybe could refactor my site without it. But for now, it does help make things a bit simpler. Especially with Dynamic HTMX queries, which cannot be statically generated on the backend when we render the HTML template. See an example here: https://haseebmajid.dev/posts/2025-04-29-til-set-dynamic-url-with-htmx-and-alpinejs/ https://haseebmajid.dev/posts/2025-04-29-til-set-dynamic-url-with-htmx-and-alpinejs/ Backend Go I moved from Python to Go about 3 years ago and honestly haven’t looked back. I really liked statically typed languages. Again, each to their own, but I think having typed data just makes your life so much easier. I also really like the smaller, better devex around Go. Fast to compile. Compiles to single static binary. Easier to put into a scratch Docker image. Simple dependency management, go mod. The CLI tool has a test runner (go test). go mod go test I really like the simplicity of Go, the code is pretty easy to read and see what is going on. I have tried to avoid using frameworks like Gin, or Gorilla. In the end, I did use Fuego, so I could generate an Open API specification. I started writing raw SQL with sqlc, so I know exactly what the query will do vs guessing with an ORM. I loved using ORMs and frameworks like Flask or FastAPI in Python but have completely reversed my opinion in Go. sqlc -- name: AddUser :one
insert into users (email) values ($1) returning *;

-- name: AddOrganization :one
insert into organizations (display_name, slug) values ($1, $2) returning *; -- name: AddUser :one
insert into users (email) values ($1) returning *;

-- name: AddOrganization :one
insert into organizations (display_name, slug) values ($1, $2) returning *; Then we can generate the SQL code by running sqlc generate which generates go code. We are going to use pgx as the underlying driver. sqlc generate pgx I am using the common 3 layer structure, controller (return HTML) -> service layer (business logic) -> store layer (DB). Postgres I remember I used to really like experimenting with different technologies like MongoDB. But these days boring is sexy for me. Like this entire stack, keep it simple, stupid. Unless you have a good reason, just use Postgres. It works there is a lot of tooling around it. For some instances, storing JSON and querying JSON, it outperforms MongoDB. DevEx A few points on the DevEx part, I really like Gitlab CI, I self-host my own runners. So speed/running out of minutes is not an issue. I am just very familiar with it. I use it alongside go-task (Taskfiles), which I found simpler than make. go-task Finally, if you know me, I always love to mention Nix, the project is set up to use Nix dev shells for all the non go dependencies, and we then have a really similar dev env and CI env.

That is my high-level experience and reason for going with this tech stack for building a SaaS. I may well go into more details about the platform I choose to help with authentication and how I intend to do authorization but for now, this is a good starting point.
