SQL Formatter: a data tool that earns its tab

Developers inheriting sprawling SQL codebases or revisiting queries from weeks earlier know the frustration: a dense, unformatted block that obscures joins, filters, and logical flow. Readable SQL isn’t cosmetic — it directly affects debugging speed, peer review accuracy, and long-term maintainability. What it is SQL Formatter restructures raw SQL into clear, conventionally formatted code, running entirely in the browser. It applies consistent indentation, capitalisation of keywords, and logical line breaks — all without altering the query’s semantics. The formatter understands the syntax of all major database engines, including PostgreSQL, MySQL, SQL Server, and Oracle, so it preserves dialect-specific functions and operators rather than flattening them into a generic style. The tool is one of 200+ free browser utilities on DevTools. It processes all input entirely on your machine — no data ever leaves the browser, no account is required, and no analytics track your usage. That privacy-first design means you can safely format queries that contain proprietary business logic embedded in production SQL. The engine handles the full spectrum of SQL complexity: basic SELECT statements, multi-table joins, Common Table Expressions (CTEs), correlated subqueries, window functions, and DML operations like INSERT or UPDATE . Because it parses the input rather than applying regular expressions, deeply nested constructs retain their hierarchy, with each subquery or CTE level indented to show ownership. How to use it Paste any SQL fragment into the left-hand editor and the formatted result appears instantly in the output panel. A live preview updates as you switch formatting options, so you can tune the output without re-pasting. The primary configuration controls help you match your team’s conventions or personal preference: Dialect : selecting a specific database ensures that functions such as PostgreSQL’s STRING_AGG or MySQL’s GROUP_CONCAT are not inadvertently mangled, and th

Tired of Searching for Different Base64 Tools? I Built One Place for Everything

As developers, we've all been there. Q: Need to decode a Base64 string? Open one website. Q: Need to convert an image to Base64? Open another website. Q: Need to validate a Base64 string? Search Google again. Q: Need to compare two Base64 values? Yet another tool. I found myself repeatedly switching between different websites, browser tabs, and terminal commands just to perform simple Base64-related tasks. So I decided to build something that solved this problem for me. The Goal Keep every commonly used Base64 utility in one place and make it work directly in the browser. No installations. No command-line knowledge required. No account creation. Just open the website and use the tool What You'll Find Instead of only providing an encoder and decoder, I wanted to cover the complete Base64 workflow. Some of the available tools include: Base64 Encode / Decode Image to Base64 Audio to Base64 Video to Base64 Base64 Validator Base64 Detector Base64 Compare Base64 Repair Base64 URL Encode Base64 File Decoder CSS Data URI Converter And more are being added regularly. Why I Built It Honestly, this started as a personal productivity project. I was using different Base64 tools almost every week and got tired of bookmarking multiple websites for related tasks. Having everything in one place turned out to be surprisingly useful, so I decided to make it public. Give It a Try https://base64converters.com I'm continuously improving it and would love feedback from fellow developers. Are there any Base64-related tools or workflows you use frequently that should be included?

Why I Log response.model on Every Claude Call (and You Should Too)

It is a one-line habit that has saved me more debugging time than any clever abstraction: I log which model actually answered every Claude request. Not which model I asked for. Which one responded. In 2026, with model fallbacks, fast-changing model strings, and routing logic, those are not always the same thing. Here is why the gap exists and what it has caught. The request model and the response model can differ You send model: "claude-fable-5" . You assume Fable 5 answered. But the response object tells you what actually served the request: const response = await client . messages . create ({ model : " claude-fable-5 " , max_tokens : 16000 , thinking : { type : " adaptive " }, messages : [{ role : " user " , content : prompt }], }); console . log ( " requested fable-5, served: " , response . model ); Most of the time they match. The interesting cases are when they do not. The Fable 5 safeguard fallback The reason this matters most in 2026 is Fable 5's safeguards. Fable 5 has hard guardrails in cybersecurity, biology, chemistry, and health. If your prompt trips one, the request does not just refuse. It silently falls back to Opus 4.8 to produce a safe answer. For my security work, this is a sharp edge. I run contract-analysis prompts that can look adversarial to a safeguard. If one trips, I am quietly getting Opus 4.8 output while believing I am getting Fable-tier reasoning. The quality difference on a hard audit is exactly the thing I paid double for, and it vanished without an error. The only way to know is to read response.model : if ( ! response . model . startsWith ( " claude-fable-5 " )) { logger . warn ( { requested : " claude-fable-5 " , served : response . model }, " Fable 5 request fell back, likely a safeguard trip " , ); } Without that log, a fallback is invisible until I notice the analysis got worse and have no idea why. Routing logic and config drift The other source of the gap is my own code. I have routing that picks a model based on task type and

I built 128 things with AI in 4 months. Then I made an AI dissect all of it.

I'm 19. In four months I built 128 projects with AI — 61 GitHub repos, 15 MCP servers, a 7-department agent OS, the works. I shipped 5 . Total stars: 6 . Revenue: $0 . That gap bothered me enough that I did the obvious-but-uncomfortable thing: I had an AI audit everything — every repo, every project folder, 4,239 build sessions, 244 memory notes — and pin it all like specimens in a cabinet. No flattery. Here's what the autopsy found. → The full interactive atlas: https://builder-archive.vercel.app/en The number that explains everything 128 built. 5 shipped. It's tempting to read that as a discipline problem. It isn't. The build velocity is real — I once shipped ~20 vertical SaaS in a single weekend on a shared Next.js + Drizzle + Stripe stack. The code works. The UIs are clean. The problem is the last mile . README writing, deployment, the final 10% that turns a repo into a thing a stranger can use — that's where almost everything died. Not ability. Execution. The AI put it in one line: "Can build anything. Finishes nothing." Strength and weakness are the same coin Here's the part I didn't want to see: the thing that makes me fast is the thing that kills me. Because I can build deep, I lose the stopping point. Because building is cheap, I start the next thing before finishing the last. The audit scored two skill axes: Build (design → implementation → automation): advanced Distribution (publish → ship → monetize): beginner Every problem I have lives in that asymmetry. It's not a motivation gap — total commits across repos: ~4,800. The effort is enormous. It just never crosses the finish line into something public. The hardest thing I made is the one I hid The audit flagged a buried asset: a GCC/ZATCA e-invoicing toolkit — Saudi Fatoora Phase 2, EN16931 + Peppol validation, secp256k1 signing, Go compiled to WASM. The single hardest, most verifiable piece of work I've done. It's been sitting in a private repo. That's the disease in one example: the more valuable the th

How I Stopped Duplicating AI Skills Across Claude Code, Cursor, Codex, Gemini CLI, and Other Tools

Has anyone else ended up maintaining the same AI skill in multiple places? I use Claude Code, Codex, Cursor, Gemini CLI, Kimi, and several other AI tools. Over time, I accumulated a huge collection of skills and workflows. The annoying part wasn't creating them. It was keeping them synchronized. A skill would exist in one format for Claude Code, another for Cursor, another for Gemini, and so on. Eventually, I got tired of duplicating everything and built an open-source project called AI Omni Skills. The idea is to keep a single source of truth and generate the formats required by different AI tools. Now I update a skill once and regenerate whatever structure a specific tool expects. I'm curious: How are you managing skills today? Are you duplicating them across tools? What integrations would you want to see? Repo: https://github.com/moatazhamada/ai-omni-skills

What it takes to build docs worth reading

Treating docs as a product When documentation lives as an afterthought, it shows. Pages drift out of date, examples break quietly, and release notes scatter across a dozen places no one can find. The fix is not a weekend cleanup. It is a decision to treat docs the way you treat any product people depend on: someone owns it, it has standards, and it gets maintained on purpose. That is the decision I made when the docs came to the Developer Relations team at the end of 2025. Not "let's tidy this up," but "this is ours now, and we are accountable for whether a developer can actually build from it." The work, in the repository The honest record of what a team does to a codebase lives in its git history, so that is where the story starts. Comparing the six months before the handoff to the six months since: Before vs. Under DevRel: Commits: 476 → 1,900+ Merged pull requests: 145 → 447 Unique contributors: 21 → 64 A repository that averaged fewer than 500 commits over half a year is now past 1,900 in the same span. The contributor count tripled, because we treated the docs as something the whole community could improve, not a walled garden. This is what a team that decided to do the work looks like when you measure it. Our proudest metric is what was cut In six months, we added roughly 339,000 lines and removed roughly 281,000. That near balance is the point. A neglected docs site accumulates: dead pages, stale tutorials, examples that no longer compile, three slightly different explanations of the same concept. Adding more on top of that does not help anyone. So we cut nearly as much as we wrote. We rebuilt the Hello World walkthrough from 1,300 lines down to about 300 without losing a thing. We consolidated scattered release notes into a single clean reference. A docs site is judged by what a developer can find and trust, not by how much sits on the shelf. A library you can learn from At the start of the year, the examples library had effectively one usable entry. Today,

How to Reduced Load Time From 5 Seconds to 1 Second

The Problem: How Website Slow Performance Costs Businesses Revenue A slow website doesn't just frustrate users it actively costs businesses money. Every additional second of load time causes visitors to leave, damages your search engine rankings and directly reduces conversions. Research shows that pages taking 5 seconds to load have a bounce rate 75% higher than pages loading in 1 second. For e-commerce sites, this translates to thousands of dollars in lost sales monthly. Recently, we worked with a client experiencing exactly this problem. Their website averaged 5-second load times, resulting in high bounce rates, poor mobile performance and declining search visibility. They needed immediate action. The Initial Audit: Identifying Website Speed Bottlenecks Before implementing solutions, we performed a comprehensive website audit using industry-standard tools like Google PageSpeed Insights, GTmetrix and WebPageTest. Step 1: Image Optimization – The Biggest Win Images typically account for 50-80% of page weight. Optimizing images delivered the most dramatic performance improvements. What to do: Converted to Modern Formats – We converted all PNG and JPEG files to WebP format, which provides 25-35% better compression than traditional formats while maintaining visual quality. Aggressive Compression – Images were compressed using lossless and lossy techniques without perceptible quality loss to users. Implemented Lazy Loading – Below-the-fold images were set to load only when users scrolled near them, not on initial page load. Responsive Images – Different image sizes were served based on device screen size, so mobile users didn't download desktop-sized images. Step 2: Minifying and Deferring Code – Eliminating Render-Blocking Resources JavaScript and CSS files were creating significant render-blocking bottlenecks. What to do: Minified CSS and JavaScript – Removed unnecessary characters (spaces, comments, line breaks) from all CSS and JavaScript files. Removed Unused Code

Diff Checker: a small tool that solves a specific problem

Code reviews, configuration changes, and debugging sessions demand precise understanding of what changed between two versions of text. Manual comparison of large blocks of code or configuration files is error-prone, and version control diffs don’t always provide a quick, focused view for sharing or verifying changes outside a repository. What it is Diff Checker is a browser-based text comparison tool that performs line-by-line analysis of two text blocks and highlights differences with color-coded visual indicators. It processes text entirely in the browser—part of the 200+ free tools on DevTools—meaning no data is uploaded or stored, a privacy‑first design. The interface uses a split‑pane layout: original text on the left, modified text on the right. As you paste or type, the comparison engine recalculates the diff in real time, marking added, removed, and changed segments so differences are immediately clear. Several configuration options tailor the analysis. Toggling whitespace sensitivity ignores differences in indentation or blank lines, useful when comparing code from teams with different formatting conventions. Case sensitivity can be turned off for text where capitalization inconsistencies are irrelevant. A swap button reverses the comparison direction with a single click, handy when the assignment of “original” and “modified” is accidentally reversed. How to use it Paste the original text into the left panel and the modified version into the right panel. The diff view updates instantly, so you don’t need to press a button to see changes. For code, the process is straightforward. Drop a baseline function on the left: function calculateTotal ( items ) { let total = 0 ; for ( let item of items ) { total += item . price ; } return total ; } And the updated version on the right: function calculateTotal ( items , taxRate = 0 ) { let total = 0 ; for ( let item of items ) { total += item . price * ( 1 + taxRate ); } return Math . round ( total * 100 ) / 100 ; } The
