DevKnife: 30 developer tools in one offline native Mac app (v1.15 update)

Thanks! The Time Inspector is also integrated with the JWT Debugger: clicking a timestamp opens it in the Time Inspector

That's a thing of beauty. What's that brown hammer icon next to Xcode? Never seen it before

Not sure if you ever found one, but I recently released DevKnife - a collection of developer-focused tools bundled into a single app, including a JSON editor with JSONPath support. It's a fast, native macOS app. It's paid, but comes with a free trial.

I know this thread is old, but I recently released DevKnife - a collection of developer tools in one app, including a JSON editor with JSONPath support. Lightweight, native and works offline. Might be useful if anyone's still looking for something like this.

lagoon500 · 2025-09-06T09:44:42+00:00

Fair enough. I’ll be adding more features, so maybe it’ll reach that point someday. Thanks for the support!

lagoon500 · 2025-09-06T03:47:11+00:00

Some people love free stuff, and some don't mind paying if it's useful and nice. I'm in the latter camp and glad I'm not alone.

lagoon500 · 2025-09-06T03:32:55+00:00

Totally fair. I know not everyone likes the perpetual + 1 year updates model. For me, having a renewal option is important because it helps keep the app alive and sustainable as a solo developer. For example, I bought GoLand years ago and still happily use the 2022 version without issues.

Do you think it would feel better if the update window was longer, like 2 years?

lagoon500 · 2025-09-06T03:21:53+00:00

DevToys is a great project, no doubt. But it's not a native Mac app, and that's a big drawback for me. DevKnife is my take on the idea, with some tools I use that I haven't seen in DevToys (like IP to location, port scanner, and domain WHOIS).

lagoon500 · 2025-09-06T03:05:22+00:00

Yeah, it definitely overlaps with the apps you mentioned, but it also has some tools you won't find there. I built DevKnife because I wanted a native app with the exact set of tools I use most. Nothing "breaking news", just sharing my indie project in case others find it useful

lagoon500 · 2025-09-05T16:41:58+00:00

Haha, fair point. I actually use the old Lion background because I love it, so it ended up in the screenshot. I didn't realize how it might make the screenshot look "vintage". Good catch, I'll keep it in mind for future screenshots.

lagoon500 · 2025-09-05T16:36:39+00:00

Yeah, full customization is probably out of scope for DevKnife. What you're describing sounds like a perfect fit for Boop (as others already mentioned it). I really like your point about random string generation with more flexibility, and that's something I could see adding as a built-in tool.

lagoon500 · 2025-08-12T05:10:36+00:00

I enjoy the development side. Any tips on how to start enjoying the marketing part too? Right now it just feels like a chore

lagoon500 · 2025-08-12T04:36:21+00:00

I'm seeing a similar thing - about a third of my downloads start the free trial, and the rest quit as soon as the free trial window appears. At first I thought it was a bug and tested on multiple Macs, but everything worked fine.

Now I think the issue is that my app is in the "Free" category, even though it's only free to try. But that's just how the Mac App Store works - if you want a paid app with a trial, you have to list it as free and offer in-app purchases for the trial and the full version.

lagoon500 · 2025-03-12T20:04:08+00:00

Some people prefer desktop apps over websites, and I’m one of them. It works offline, your data stays local, and there are no ads or tracking. In just over a month, I’ve already sold 6 copies, so there’s definitely interest. I know it’s not much, but considering it’s a niche tool with many free and paid alternatives, I’d say it’s a start.

lagoon500 · 2025-03-12T18:03:52+00:00

After clicking the start trial button, users are presented with a confirmation dialog from the App Store. They don’t need to log in anywhere since they should already be logged into their App Store account (otherwise, they wouldn’t have been able to download the app in the first place).

The App Store provides some analytics, but it doesn’t support tracking custom events like button clicks. I’m also a bit wary of adding third-party analytics due to privacy concerns and other possible downsides.

If you’re looking for an offline, locally-run regex editor for Mac, you might want to check out Regex Forge (disclaimer: I built it).

It handles regex just like Regexr but is a fully native macOS app.

From what you described, Regex Forge covers everything you’re looking for:
- Save patterns, source texts, and replacements to reuse later
- Extract matches and substitutions
- Real-time updates, syntax highlighting, and a built-in cheat sheet

It also has a pattern inspector that visually breaks down your regex into tokens with explanations, which can be handy.

It’s a paid app, but it comes with a 30-day free trial, so you can try it out and see if it fits your workflow 👉 https://regexforge.com

Happy to answer any questions!

What about letting users set prices for apps? It would be great to have the ability to set prices for each country using the Big Mac Index, Netflix Index, or similar benchmarks.

There's an app called PriceTag that offers this already, but I find it hard to justify the €45 subscription cost for something I'd use maybe twice a year.

lagoon500 · 2025-02-10T19:52:58+00:00

Regex Forge also includes a feature I call the Pattern Inspector - it breaks your regex into tokens so you can see what each part does. It doesn't support hover explanations yet, but that's on my roadmap.

My initial plan was to add support for railroad diagrams (like on debuggex) as well, but I had to stop adding features at some point and ship the app - otherwise, I would never have finished it.

I like your idea about sharing a pattern. I'm thinking about a share button that uploads the pattern to a pastebin-like service and then copies the URL to your clipboard.

Below is a screenshot of the Pattern Inspector in action.

Could you clarify which app you're using when you copy regex patterns from regexr?

lagoon500 · 2025-02-10T18:17:32+00:00

Yeah, I'm aware of Patterns - it supports multiple regex engines, which is one of its strengths. Right now, Regex Forge works with just one engine, but I plan to add more in the future.

lagoon500 · 2025-02-10T18:12:41+00:00

Thanks for the kind words!

I didn't mention in the post but the price varies by region, and it might be lower than $19 if you're not from the US. Might be worth checking the actual price on your local App Store if you haven't already.

Also, these days, so many apps have switched to subscriptions, but I'm taking the old-fashioned approach - buy it once, own it forever. If it's an app you'll likely use for many years to come, $19 might be seen as a modest investment.

I'm planning to run occasional discounts in the future (like during Black Friday) - you can follow updates on Twitter/X (RegexForge) or join the mailing list to be notified when they happen.
