almasix 0.4.0

Laravel's application shape, in async Python.

A full-stack web framework on FastAPI and Starlette — routing, validation, an ORM, a view engine, auth, queues, mail, cache, events, a scheduler, and a first-class CLI — arranged the way Laravel arranges them, and asynchronous all the way down.

Why Almasix

Python has excellent HTTP libraries and very few opinions about what an application looks like. Almasix supplies the opinions. It takes the conventions that make a Laravel codebase legible on first read — the directory layout, service providers, facades, fluent builders, Route groups, Eloquent-style models, Blade-style templates, Artisan-style commands — and implements them in modern Python. Requests, the ORM, queue workers, and the scheduler all run on asyncio, and the FastAPI application underneath is never taken away from you.

It is a parity project, not an homage. Each area of the framework is built against the corresponding page of Laravel's documentation, method by method, and every deliberate divergence is named in Almasix's own page for that feature — so Str, Collection, the query builder, and the scheduler behave the way your muscle memory expects, while async/await, type hints, context managers, and dataclasses are used where Python has the better answer.

| Prism (almasix.prism) | the view engine — .prism.html templates, directives, components, stacks | | Articulate (almasix.orm) | the ORM — models, relationships, migrations, pagination, on SQLAlchemy Core |

A tour in five files

Routes are declarative and grouped, controllers are plain classes, and route names and middleware sit where you'd look for them:

# routes/web.py
from app.http.controllers.post_controller import PostController
from almasix.routing import Route

with Route.group(middleware=["web"]):
    Route.get("/posts", [PostController, "index"], name="posts.index")
    Route.get("/posts/{post}", [PostController, "show"], name="posts.show")

Models carry their own casts, scopes, and relationships:

# app/models/post.py
from app.models.user import User
from almasix.orm import Model, SoftDeletes, relation


class Post(SoftDeletes, Model):
    fillable = ("title", "body", "published")
    casts = {"published": "bool", "published_at": "datetime"}

    def scope_published(query):
        return query.where("published", True)

    @relation
    def author(self):
        return self.belongs_to(User)

Controllers read like their Laravel counterparts, with await at the edges:

# app/http/controllers/post_controller.py
from app.models.post import Post
from almasix.prism import view
from almasix.http import Controller


class PostController(Controller):
    async def index(self):
        posts = await Post.query().published().with_("author").latest().get()
        return view("posts.index", {"posts": posts})

Templates are Prism — Blade's directives, compiled to Python:

{{-- resources/views/posts/index.prism.html --}}
@extends('layouts.app')

@section('content')
  @foreach(posts as post)
    <article>
      <h2>{{ post.title }}</h2>
      <p>by {{ post.author.name }} — {{ post.created_at }}</p>
    </article>
  @endforeach
@endsection

Console commands and scheduled work are declared together, and run under smith:

# routes/console.py
from almasix.console import Artisan, schedule


def send_digest(command) -> int:
    command.info("digest sent")
    return 0


Artisan.command("digest:send", send_digest).purpose("Mail yesterday's digest")

schedule.command("digest:send").daily_at("07:00").timezone("Africa/Nairobi").without_overlapping()
schedule.command("model:prune").daily().on_one_server()

Getting started

Create an application

python -m venv .venv && source .venv/bin/activate
pip install almasix

almasix new blog
cd blog
pip install -e .        # the framework requirement is already satisfied
python smith serve      # always works; bare `smith` also works after this install

almasix new writes a complete application: app/, bootstrap/, config/, routes/, resources/views with error pages, database/migrations, storage/, a Vite config, and a root smith script. Prefer python smith … from the app root (same idea as php artisan). Installing the application (pip install -e .) also links a smith console script into that virtualenv. Installing only the framework gives you the global almasix command — not smith.

Work on the framework

git clone https://github.com/almasix-dev/almasix.git && cd almasix
python -m venv .venv && source .venv/bin/activate
pip install -e ".[dev]"

make test          # full unit + smoke suite
make test-cov      # the same, with the coverage gate
make lint          # ruff
make docs          # the documentation site, locally

What ships today

The framework is built in milestones, each closed against a Laravel documentation page. Closed today:

• The basics — routing and route groups, controllers, middleware and aliases, requests and responses, session, CSRF, validation with form requests, URL generation, error handling and the debug page, logging, asset bundling.
• Prism views — layouts and sections, includes, control directives, components and slots, stacks, and a dd() dump page.
• Articulate ORM — models with casts and serialization, the whole relationship surface, eager loading, soft deletes, pruning, migrations, seeding, pagination, and streaming reads through lazy collections.
• Digging deeper — the Smith console with prompts and closure commands, the task scheduler (frequencies, constraints, hooks, sub-minute tasks), cache, Redis, queues and workers, mail, notifications, events, the filesystem, collections, helpers and Str, the HTTP client, localization, and encryption.
• Security — authentication guards and providers, hashing, gates and policies, email verification, password confirmation and resets.

Every closed milestone ships four things: the implementation, tests, a documentation page, and a runnable demonstration in the living example app.

Documentation

website/ holds 54 pages of application-developer documentation (Astro Starlight), written to follow Laravel's structure page for page — including a section per method for collections, strings, and helpers. Read it at almasix-dev.github.io/almasix, or run make docs for a local copy at http://localhost:4321.

examples/progress is the living example — a real Almasix application that demonstrates each closed milestone through routes you can visit and smith progress:* commands you can run. Its /progress page is the project's milestone board.

How the project is built

docs/PLAN.md is the binding architecture and milestone document: 51 milestones, each mapped to the Laravel documentation it must match, with the parity audit and the named deviations recorded in place. docs/SMOKE.md records the exit criteria that close a milestone.

The gates are enforced in CI on Python 3.11, 3.12, and 3.13:

make lint runs ruff check and ruff format --check against an exact ruff==0.16.6 pin and an explicit rule selection (E4,E7,E9,F,I,UP,B,RUF100).

Currently 1,886 tests at 99.38% coverage.

Status

M39 docs journey and M38 deployment ops closed on the stability track (after M51, M44, and the M25 Mongo audit). Package version is 0.4.0 in-tree — tag/publish when you cut the GitHub Release. Next up: M37 — API tokens. See docs/PLAN.md.

Contributing

Read docs/PLAN.md first — it is the source of truth for what belongs where and what parity means for the area you are touching. Work in milestone order, keep the coverage gate green, add the documentation page alongside the code, and extend examples/progress so the new surface can be demonstrated, not just claimed.
