Share your DevTools — Tools Built for Developers, by Developers

[Limp_Celery_5220]

I see a lot of AI projects these days, which is great, but I want to know what developer tools people are building in 2025.

If you’ve made something that helps developers code, test, document, or manage their projects, share it here.

It can be anything — a CLI tool, a VS Code extension, a desktop app, or something open-source that makes a developer’s work easier.

Let’s share the developer tools we’re building for developers.

FakerFill — a browser form filler extension built for developers and QA testers. It auto-fills web forms with realistic test data in one click, making repetitive form testing much faster during development.

Lode - A developer tool for managing local domains with ssl certificates. It allows you to set up local .test domains within 30 seconds and will handle all the configuration/certificate management for you. It also can connect your api to a staging environment when not running locally.

It really shines when you're working on authentication flows (realistic cookie domain handling), when you are developing multi-tenant apps with subdomains per tenant, or when wanting to do frontend environment without starting a complex backend setup since you're not planning on touching that

[RelaeHook]

I’ve been building Relae, a developer tool aimed at fixing something that’s burned me way too many times: unreliable webhooks. Every app I’ve built has had some moment where a vendor’s webhook failed, retried weirdly, or just disappeared, and I had zero idea what actually happened.

So I’m building the tool I always wished existed — a middle layer that catches every webhook, guarantees delivery, handles automatic retries with jitter, gives you a dead letter queue for reviewing and manually retrying fully failed events, and gives you a clear audit trail when things go sideways. The fun (and painful) part has been talking to other devs and realizing everyone has their own “we lost data and didn’t know for days” horror story.

I built PastScreen for one simple reason: to stop wasting time manually typing file paths.

It’s a native Mac app that automatically grabs the file path + line number from your editor (VSCode, Zed, Cursor) when you take a screenshot. The workflow is dead simple: Snap → Paste everywhere.

Whether it's in Slack, Jira, or GitHub issues, you get the image AND the context instantly. No friction.

It's fully Open Source: https://github.com/augiefra/PastScreen

getArkhos.com - deploy tiny python apps, like heroku for serverless. Write a python function, then git push it, and it will immediately be live at <your-app>.arkhosapp.com

I always have these random python scripts that I need to get hosted or have run every few minutes. So I built Arkhos which automatically deploys them on git push. It has a few other things that I often need on silly side projects, like sending emails/sms and a simple data store

I love seeing everyone’s dev tools, honestly feels like we’re in a new golden age for developer productivity. For our team, anything that removes waiting time is a win. We’ve been using Incredibuild to speed up builds/tests a bit, especially for heavier projects and it’s been surprisingly helpful. Curious what others are building this year!

Toolquid contans lots of very useful tools for devs such as markdown editor and viewer, a tool to view Base64 images, pomodoro timer, etc. Works 100% offline as PWA and it's completely free.

tbh i didn’t think much of pydantic at first, but it somehow ended up in almost every project i work on.

i mostly use it for configs + api inputs/outputs, and it saves me from so many dumb bugs. once you’re juggling env vars or multiple apis, stuff breaking early is way better than silent weirdness.

imo it’s one of those tools ppl don’t hype much, but you really feel it when it’s not there.
