I’ve been iterating on Toolbit (https://toolbit.app), a local developer utility app I initially shared a while back.
It started as a small attempt to stop bouncing between dozens of web tools for things like JSON/JWT, base64, regex testing, cron expressions, and similar “glue work” tasks. Over time it’s grown into something I keep open all day.
Since the last time I mentioned it, I’ve added quite a bit:
• ~40+ tools now (regex tester, PDF merge, image conversion, cron builder, etc.)
• workspaces for grouping tools around a task
• tool chaining instead of constant copy/paste
• snippets, history, and recent items
• automatic detection (paste data, it routes you to the right tool)
It’s an Electron app and runs fully local. No accounts, no tracking, no sending data out. The goal isn’t novelty, just reducing friction in everyday dev work.
I’m still smoothing rough edges and figuring out where this is most genuinely useful. Curious how others here think about scope creep vs. “daily driver” utility tools, and what’s worked or failed for you in that space.
I’m a full-stack engineer with 12+ years of experience in multiple languages and technologies and available immediately. I have very good experience in architecture, design and development of scalable web applications.
I’ve shipped multiple apps that are largely LLM-assisted. One of it is called Toolbit (Repo: https://github.com/alwin-augustin/toolbit), which is a collection of 20+ dev utilities like formatting JSON, generating UUID, JSON validation etc. I have been using JSON formatters all the time, but worried about whether they are sending it to server and so built this one so as it will do the processing on client side only.
Another application I have built is Remotedays (remotedays.app), which is a compliance tool for Luxembourg based companies to track cross border workers. This is recently finished and starting to reach out initial customers. There is a demo for this app is available in public at demo.remotedays.app
I have used Claude Code and Google Antigravity IDE. The Antigravity is used whenever I exceeded the Claude limits (which happens often). If you have an architecture about the product in mind, you can clearly use these tools as force multipliers. In my experience, Claude is the best, especially when you use it with the skills.

I was getting these messages for sometime and installed it finally. It is the same app that is mentioned in the article. My phone is already in the system then.
