A super-fast SaaS site built with rust, actix-web, and htmx, with a fully-passwordless authentication system.

Keep track of what you want/need to to, but with an appropriate tone. Have a little fun! Things don't have to be serious all the time, get a little silly.
Watch our video to see what it's like to use!
We all have different ways of being motivated. Maybe you need nice gentle reminders without too much pressure. Or snarky and mean keeps you going. Or just basic and simple. Choose one of our pre-defined tones or create your own.
Divide your goals into groups and set different tones for different groups. Or keep them all in one group.
Sometimes it's important to have hard deadlines. Sometimes it's important to not have deadlines. Our pre-defined tones handle deadlines in different ways, or define your own with soft, hard, or no deadlines.
Ok so it's basically a Kanban app, but it's sillier!
We all love rust. Type safe and if it compiles it works. Just a joy
Actix Web is probably the largest web framework for Rust and it's the one that I know. It worked quite well for building up this application.
Using sqlite, and Litestream, the database can be right on the web server, super fast, and still have the durability and rollback of a managed database service. It's also very simple to use and deploy compared to a full postgres setup.
Sqlx provides compile check sql queries, just incredible for correctness and developer experience. It can also help with fast iteration, because rather than looking up the correct sqlx, you can just guess and get an error code right in your editor.
The passwordless authentication has two core components: email and passkeys. Email auth is straightforward, a temporary code is generated stored on the session, and then sent to the user's email. (I'm using redis for session storage, obviously this would be horribly insecure using any kind of client-side session) Pretty basic stuff at this point.
Passkeys (WebAuthn, FIDO2, so many names…) use device based authenticators and public key auth to verify users. It's more secure and much more user friendly. I'm using the webauthn-rs crate and Simple WebAuthn javascript library to do most of the heavy lifting (and the nightmare that is base64 encoding and decoding). Logged in users can register their device and then login with just that device next time.
HTMX gets me very close to my goal of never writing any javascript, or, at least, not needing a javascript framework. I wrote the whole thing as a traditional Get-Post-Redirect server-side web app, and then enhanced everything with htmx with just a few lines of rust (and a custom extractor). With htmx's dynamic swapping of components, it's simple to send back chunks of html, rendered from the same templates, and gives the user a mostly reload-free experience that feels as responsive as a SPA. Additionally, if a user does reload, they will find themselves just where they were before, because the same endpoint will render the whole page if the request isn't made from htmx.
As a result of using htmx, the total download size of the site is quite small compared to a SPA, and using htmx often allows me to skip database quries, which is huge in io-bound applications like websites.
Yeah it's tailwind. It's the best css framework. I don't want to write my own css, I want to make things that look nice. If I need to change something, I'll just use sed.
I tried a bunch of stuff that seems super cool shuttle.rs seems awesome, but scale-to-zero means sometimes the site just isn't there, and fly.io is cool but free-ish and just not all that special.
It's on a server. Turns our, for small sites, docker-compose on a free-tier OCI server is just fine. I don't like forgetting what's all on a server though, so I used NixOs and Arion and deployed it using morph. This means it's all declarative, so in six months I can just read the config file and I'll know exactly what's running and can just move it to another server. Since litestream auto-downloads the latest database, it would just work™. Not that I'm going to on purpose.
