About FixDevs

FixDevs is an independent reference for developer error fixes. Every article is built around a real error message — the kind you paste into Google after a build dies at 2 a.m. — and starts with the exact command, log line, or stack trace you would actually see.

The goal is to be the page you only need to read once. No backstory, no "let's learn about Docker" preamble — just the error, why it happens, and the fix that works.

Who Runs This Site

FixDevs is run by a solo developer based in Japan with over 15 years of professional software experience across backend services, infrastructure, and frontend tooling. The same person writes, edits, tests, and updates every article on the site — there is no remote content team and no outsourced writing.

Day-to-day work spans the same stacks the site covers: Python (FastAPI, Django, asyncio), TypeScript and Node, React and Next.js, Docker and Kubernetes, PostgreSQL and Redis, and the long tail of CI/CD, Linux, and cloud infrastructure that holds it all together. Articles draw on errors actually encountered in real projects, not synthetic examples invented for SEO.

How Articles Are Made

Every article follows the same workflow. The short version is on this page; the full process — including what gets verified, how AI-assisted drafting is used, and when articles are updated — lives on the Editorial Methodology page.

  1. Pick a real error. Article topics come from errors we have actually hit in production work or that show up repeatedly in support channels and bug trackers — not from keyword tools alone.
  2. Reproduce it. Where practical, the error is reproduced in a clean environment so the message, stack trace, and exact version numbers are accurate.
  3. Cross-check the fix. Solutions are cross-referenced with official documentation, the project's source code, GitHub issues, and release notes before publishing. Stack Overflow answers are starting points, not sources of truth.
  4. Cover the edge cases. Each article includes a "Still Not Working?" section with less obvious causes that most pages skip — environment-specific gotchas, version-specific behavior, platform differences.
  5. Update when reality changes. When a tool releases a new major version, deprecates an API, or changes default behavior, the affected articles are revisited. Articles carry a visible Updated date when this happens.

What the Site Covers

FixDevs focuses on errors that interrupt developers mid-task. The fixes fall into ten broad categories — see all categories for the full tree.

What This Site Is Not

FixDevs is not a tutorial site. It does not teach languages or frameworks from scratch — there are excellent free resources for that already. The site assumes the reader is mid-task and needs a specific fix, not a general explanation.

FixDevs is also not affiliated with any of the projects, vendors, or services discussed in articles. There are no sponsored articles. Links to specific tools or services are based on technical merit, not commercial relationships.

Use of AI in Article Drafting

Some articles are drafted with AI assistance to accelerate the initial outline and code-example generation. Every AI-assisted draft is then reviewed, edited, fact-checked, and tested by the author before publishing. AI output is never published unedited.

The reason for being explicit about this: Google's guidance on AI-generated content is that the substance — accuracy, originality, helpfulness — matters more than the production method, and FixDevs aims to meet that bar regardless of how the first draft was produced. Readers benefit when authors are transparent about their tools.

Corrections and Reader Feedback

If an article is wrong, outdated, or missing an important edge case, please tell us. Corrections are taken seriously and acted on quickly — the goal is to be the page you only need to read once, and an inaccurate page fails that test.
