About
Logics Guru is a developer knowledge and tools platform: tutorials, technical guides, articles, code snippets and reference material, plus a growing set of free developer tools that run in your browser.
Who runs it#
There is no agency behind this and no content team. Everything published here was written by one person, which is also why it is published slowly — and why every article is something actually used rather than something commissioned.
Why it exists#
Most of what I know was learned by getting something wrong first. This is where I write that up: the architecture decisions and what they cost, the debugging sessions that took a day and should have taken ten minutes, and the small utilities I kept rebuilding from scratch until I put them somewhere permanent.
The test for anything published here is simple — would it have saved me time if I had found it when I needed it?
Why the tools run in your browser#
Developers paste real data into online tools: production JSON, live access tokens, configuration files containing secrets. Sending that to somebody else's server is the wrong default, however trustworthy the server. Every tool here processes your data on your own device wherever it is technically possible, and each tool page states plainly which of the two it is.
There is currently one exception, and it is unavoidable: a link shortener has to keep the URL you gave it, because a server needs to look the destination up again later. That tool says so on its own page rather than hiding behind a general promise.
Work#
The services section exists because the same person writing this material builds production software for a living. It is deliberately secondary — the content is the point, and the site is not a brochure with a blog bolted on.
What you will not find here#
- Invented testimonials, or client logos I have no right to display
- Statistics I cannot source
- Thin articles written to fill a keyword gap
- Tools that quietly upload your input while claiming otherwise
