24 alternatives to Build Local-First Apps(WASM+SQLite)

Hey, everyone! SkyAlt is a browser and SDK for Local-first applications at the top of SQLite files. One and half months ago, I started working on the idea of rebuilding some software as services I use into local-first apps. SkyAlt is a combination of SQLite(storage), WASM(app binary) and JSON(settings, communication). I decided to build my own 'browser', which has around ~10K LOC and has nothing to do with WebKit(HTML/CSS/JS) or Chromium. Apps use immediate mode GUI to draw and communicate with Skyalt. The layout is a flexible grid. Apps are written in the Go language. Right now…

    I recently released v3 of Base, my SQLite editor for macOS. The goal of this app is to provide a comfortable native GUI for SQLite, without it turning into a massive IDE-style app. The coolest features are - That it can handle full altering of tables, which is quite finicky to do manually with SQLite. - It has a more detailed display of column constraints than most editors. Each constraint is shown as an icon if active, with full details available on clicking the icon. This update also adds support for attaching databases, which is a bit fiddly with macOS sandboxing. I'd love to hear any…

    Hey HN, I’m Jimmy, co-founder of Dropbase (https://www.dropbase.io). We are an internal tools builder for Python developers. All you have to do is import any Python scripts/libraries, declare UI components, and layer app permissions so you can share them with others. We’re a middle ground between Airplane and Retool—simpler UI creation than Airplane, more code-centered than Retool. UI building is declarative and you can bind Python scripts/functions to UI components. You can write Python scripts/functions using our App Studio with support from a Python Language…

    I make a no-CGO Go SQLite driver, by compiling the amalgamation to Wasm, then loading the result with wazero (a CGO-free Wasm runtime). To compile SQLite, I use wasi-sdk, which uses wasi-libc, which is based on musl. It's been said that musl is slow(er than glibc), which is true, to a point. musl uses SWAR on a size_t to implement various functions in string.h. This is fine, except size_t is just 32-bit on Wasm. I found that implementing a few of those functions with Wasm SIMD128 can make them go around 4x faster. Other functions don't even use SWAR; redoing those can make them 16x faster.…

    Hi HN! I left AWS a few months ago and created CodinIT, a local, open-source AI app builder made with remix + Electron. The motivation: I tried one of the popular cloud-based AI app builders, but when I pulled down the app to run locally, it just didn’t work especially with the monthly costs needed to build something half decent without being limited. So I created CodinIT, an app builder that runs fully on your computer, making it easy to switch between CodinIT and coding tools like Cursor or Claude Code.

    Hi HN! I’m Dillon, the founder of Celest (https://celest.dev). Celest is a backend-as-a-service that lets you build full-stack Flutter and Dart apps without leaving your IDE. There’s a short demo video here: https://www.youtube.com/watch?v=Evs1f0zHpzk At AWS, I built the Amplify Flutter framework and saw the extraordinary power (and complexity) the modern cloud presents. I wore many hats in that role, but the hat I most disliked was devops. I just wanted to write my business logic and have it work. As a Flutter developer, I love writing Dart, and I want to use it…

    Hi HN! If you've ever tried to build a desktop app, you probably understand our frustrations with how challenging it is to build one and make it available on Mac, Windows, and Linux. Even with Electron, you still have to set up your own build pipelines, updating mechanisms, code-signing, deployments, and deal with cross-platform compatibility issues. We built EXT to make building cross-platform desktop software easier! Dog-fooding our own APIs, we ported 36 initial games and utilities to the EXT store (all free), and we've open-sourced all of them: https://github.com/extpkg If…

    Hello HN! I'm building mvsqlite, a distributed variant of SQLite with MVCC transactions, that runs on FoundationDB. It is a drop-in replacement that just needs an `LD_PRELOAD` for existing applications using SQLite. I made this because Blueboat (https://github.com/losfair/blueboat) needs a native SQL interface to persistent data. Apparently, just providing a transactional key-value store isn’t enough - it is more easy and efficient to build complex business logic on an SQL database, and it seems necessary to bring a self-hostable distributed SQL DB onto the platform.…

    I've spent the past couple of weeks building a Wasm-to-Go translator. It supports a subset of Wasm useful enough to translate SQLite into 600k LoC (~20 MiB) of Go code. It already passes all of my Go SQLite driver's tests across the 20 platforms I support. Performance compared to https://wazero.io/ is a bit of a mixed bag: code that frequently crosses the Go-Wasm boundary improves, but code that spends most of its time in "Wasm land" doesn't. There's probably room for improvement (I'd love to hear your ideas), but this is also a testament to how good the wazero AOT compiler…

    Hey HN, manyminiapps is the world first massively multiplayer online mini app builder (MMOMA) *Here’s what it does:* You load the page. You write 1 prompt and you get a mini app back in under 2 minutes. There’s no sign up, and you can see what everyone’s creating in real-time! Each mini app comes with it’s own database and backend, so you can build shareable apps that save data. *What’s different* There are a lot of app builders that promise you’ll build production software for others. But we think true production software can take a long time to get right. Even if you don’t need to program…
