devtiers: A Searchable Directory of Free Developer Tools

Ucscode — Wed, 22 Jul 2026 15:55:08 +0000

I put together devtiers after getting tired of the usual "free tools for developers" lists — the ones that are just a wall of text, no search, no filtering, and half the links dead within a year. devtiers is a searchable, categorized directory of free developer tools — hosting, databases, auth, monitoring, APIs, and more — built so you can filter by category and find what you need in seconds instead of scrolling a stale blog post.

What devtiers actually does

Search-first, not list-first. Type what you need — "auth," "vector database," "CI" — and get matching tools instead of scrolling an entire page.
Categorized by use case. Tools are grouped by what they solve, not dumped alphabetically or by popularity.
Visual, not just text. Each entry is scannable at a glance, so comparing options doesn't mean opening ten tabs.
Maintained, not abandoned. Free tiers change or disappear often, so this gets updated instead of sitting frozen like most lists in this space.

Who this is for

Solo developers, indie hackers, and small teams who are building something and don't want to default to a paid plan out of habit before checking whether a free tier already covers what they need. It's especially useful early in a project — side projects, MVPs, portfolio builds — where cost matters and you don't yet know which tools you'll actually stick with long-term.

Why I built it this way

There are already a few directories out there covering free developer tools, and credit where it's due — the idea of collecting these tools in one place isn't new. What I wanted was a better interface on top of that idea: something searchable and filterable instead of a long scroll, with a visual layout that makes comparing options faster. devtiers is my take on making that experience less tedious, not a claim that the underlying concept is original.

Frequently asked questions

Is devtiers free to use?
Yes. devtiers itself is free to browse and search. It's a directory of tools, not a paid product.

What categories of tools does devtiers cover?
Hosting, databases, authentication, monitoring/observability, APIs, CI/CD, and general developer utilities — with more categories added as the directory grows.

Do I need to sign up to use devtiers?
No account is required to search or browse the directory.

Can I suggest a tool to be added?
Yes — suggestions for tools to include are welcome as the directory continues to grow.

If you're auditing your stack, starting a new project, or just tired of Googling "best free X for developers" and getting the same recycled list every time, devtiers.vercel.app is worth a look.

TypeScript 7 Just Went GA — Here's What Actually Changes for Your Build

Ucscode — Tue, 21 Jul 2026 09:29:03 +0000

Microsoft shipped TypeScript 7.0 as generally available on July 8, 2026, and if you've scrolled past the headline numbers without reading further, here's the one-line version: the entire compiler and language service was rewritten from scratch in Go, and it is not a small upgrade. Microsoft's own benchmark on the VS Code codebase — 1.5 million lines — showed type-checking drop from 125.7 seconds to 10.6 seconds. That's not a typo. That's an 11.9x speedup on a codebase most of us would consider massive.

I want to walk through what's actually different, what breaks, and what you should do about it this week — not in six months when your CI is already on fire.

Why Go, and why now

TypeScript has run on its own JavaScript-based compiler since 2012. As codebases scaled into the millions of lines, that compiler became the bottleneck everyone quietly tolerated — slow CI runs, laggy IntelliSense, editors that froze on large monorepos. The project, internally codenamed Project Corsa, ported the compiler to Go rather than rewriting it conceptually. Microsoft's team evaluated Rust but went with Go specifically because its structural similarity to the existing code allowed a near line-by-line port, and because goroutines made it straightforward to parallelize type-checking across CPU cores — something the old single-threaded compiler simply couldn't do.

That distinction matters: this is a port, not a redesign. The type-checking behavior and algorithms were deliberately preserved. Code that compiles cleanly under 6.0 should compile identically under 7.0, assuming you're not relying on the old compiler's programmatic API.

What actually breaks

Two things trip people up on upgrade:

6.0's deprecations become hard errors. If you've been ignoring deprecation warnings, TypeScript 7 stops being polite about it.
No stable programmatic API yet. If your tooling — linters, custom build scripts, editor plugins — depends on tsc's internal API rather than just calling the CLI, you're stuck on 7.1 for now. Microsoft ships a compatibility binary alongside 7.0 specifically so API-dependent tooling can keep running on the legacy JS compiler while your builds move to the fast one.

The practical move most teams are making: point tsc and CI type-checks at the new native compiler immediately, and leave anything that touches the compiler API pinned to the legacy binary until 7.1 lands.

The part nobody's CI dashboard tells you

Here's the thing about a 10x build speedup — it's genuinely great, but it also exposes how much of your stack was quietly compensating for slow type-checking. Teams had added caching layers, split monorepos into smaller packages just to keep CI sane, or paid for beefier CI runners specifically to eat the type-check tax. A lot of that infrastructure is now dead weight, and dead weight on your stack usually means dead weight on your bill.

I ran this audit on my own setup last week: CI minutes down, so I dropped a tier on the runner, cut a caching step I no longer needed, and cross-checked a couple of paid add-ons against devtiers to see which ones had a free equivalent doing the same job. Ended up cutting two of them entirely.

Migration checklist

If you're planning the upgrade this sprint, here's the order that avoids surprises:

Run npm install -D typescript@latest in a branch, not main
Check for anything importing from typescript's internal API (search your repo for import * as ts from 'typescript' used beyond basic CLI wrapping)
Fix deprecation warnings from 6.0 before you upgrade, not after — they're errors now
Re-benchmark your CI type-check step and actually record the before/after numbers; you'll want them to justify downsizing runner specs
If your CI is now finishing type-checks in seconds instead of minutes, revisit whether you still need whatever caching or parallelization hacks you built around the old bottleneck

For the benchmarking step, the TypeScript 7.0 release notes have the official flags for isolating type-check time from emit time — don't just eyeball your total CI duration, since bundling and tests will drown out the actual signal.

The bigger pattern

This is part of a broader shift happening across the JS tooling ecosystem — esbuild, swc, and now tsc itself moving compute-heavy work into native binaries instead of JavaScript. The interpreter tax that's been baked into JS tooling since forever is quietly getting removed, one tool at a time.

If TypeScript's compiler can get 10x faster without changing a single line of how you write code, it's worth assuming the rest of your stack has similar slack in it. devtiers is a decent starting point for that kind of pass — a searchable list instead of a stale blog post — but honestly any hour spent auditing your paid tools against what's changed in the last year tends to pay for itself.

Anyone already running 7.0 in production CI? Curious what your before/after numbers looked like — drop them below.

Automate HTML Tables Generation in PHP with this Modern Library

Ucscode — Sun, 02 Mar 2025 19:28:30 +0000

Imagine writing a single line of code that will generate a fully functional table like the one below:

Interestingly, this is not based on random data but one that fully aligns with your project. Yes, a simple line of code can create a modular and customizable table from your database information.

The Struggle With HTML Tables

If you've ever worked with HTML tables in PHP, you know how tedious they can be. Manually writing out <table>, <tr>, and <td> elements for dynamic content quickly becomes messy and unmanageable. Developers often resort to concatenating strings or using templating engines, but these approaches come with their own challenges:

Error-prone: A missing closing tag can break your entire layout.
Difficult to maintain: Making changes to table structure requires rewriting large chunks of code.
Limited flexibility: Applying different styles, attributes, or handling special cases can get complicated.
Reusability: Managing dynamic data across multiple tables can be cumbersome.

Tables are one of the most common elements in web development. Whether it's an E-commerce product listing, admin user management, or a helpdesk ticket system, generating tables is a repetitive task.

Introducing: The Ucscode Table Generator

Wouldn’t it be great if generating tables in PHP were as simple as working with arrays or objects? That’s exactly what Ucscode/table-generator offers—a structured, object-oriented approach to creating and managing HTML tables efficiently.

🚀 Basic Usage: Creating a Simple Table

Let’s start with a simple example. Suppose you want to generate a table displaying user data from an associative array:

$data = [
    [
        'id' => 1, 
        'name' => 'John Doe', 
        'email' => 'john@example.com'
    ],
    [
        'id' => 2,
        'name' => 'Jane Doe', 
        'email' => 'jane@example.com'
    ]
];

With Ucscode Table Generator, you can generate a table effortlessly:

use Ucscode\HtmlComponent\TableGenerator\Adapter\AssocArrayAdapter;
use Ucscode\HtmlComponent\TableGenerator\TableGenerator;

$adapter = new AssocArrayAdapter($data);
$tableGenerator = new TableGenerator($adapter);

echo $tableGenerator->render();

🖥️ Output:

<table>
    <tr>
        <th>ID</th>
        <th>Name</th>
        <th>Email</th>
    </tr>
    <tr>
        <td>1</td>
        <td>John Doe</td>
        <td>john@example.com</td>
    </tr>
    <tr>
        <td>2</td>
        <td>Jane Doe</td>
        <td>jane@example.com</td>
    </tr>
</table>

🔍 Breaking It Down

Adapters: Making Data Work

The AssocArrayAdapter is just one of many adapters. An adapter is responsible for accepting a specific data type and converting it into a format that the TableGenerator can process.

Working with an associative array? Use AssocArrayAdapter.
Fetching data from MySQL? Use MysqliResultAdapter.
Want to process API responses? You can create a custom adapter.

TableGenerator: Your Table Engine

The TableGenerator takes the adapter and processes the extracted data into an HTML table. This method keeps data separate from presentation logic, improving clarity and maintainability.

✅ Why This Approach Works

No messy HTML strings – The library handles all the markup.
Clearer structure – Data remains separate from presentation.
Easier maintenance – Updating the table structure is straightforward.

🔥 Advanced Features

Adapters for Different Data Sources

One powerful feature of this library is its ability to work with various data sources through Adapters. For instance, if your data comes from an API, you can create a CustomApiJsonAdapter to process the response effortlessly.

Customization: Enhancing Your Table

By default, the table is plain. But you can fully customize it with Middleware to modify columns, apply styles, or add interactive elements.

Middleware: The Power of Modification

Middleware allows you to transform table data dynamically without modifying the core logic.

📌 Example: Adding Checkboxes to Rows

Checkboxes are essential for bulk actions. Instead of manually adding <input> elements, use CheckboxMiddleware:

use Ucscode\HtmlComponent\HtmlTableGenerator\Middleware\CheckboxMiddleware;

$tableGenerator->addMiddleware(new CheckboxMiddleware());

This automatically inserts a checkbox into the first column of each row.

📌 Why Choose `Ucscode/table-generator`?

Lightweight – No unnecessary dependencies.
Flexible API – Works for both simple and complex use cases.
Extensible – Supports custom middlewares and adapters.
Beginner-Friendly – Quick setup with minimal learning curve.
Open Source – Free to use, modify, and contribute!

How To Handle Custom S/DQL Queries On Different Database Engine with DoctrineExpression

Ucscode — Sun, 27 Oct 2024 03:40:46 +0000

In the journey of building robust Symfony projects, there often comes a point where simple Entity Repository methods like findBy() are no longer sufficient. For me, that point arrived, and I reached for the power of custom DQL queries to handle more complex data retrieval needs. At the time, I was using MySQL as my default database. Everything worked perfectly until I containerized my project and decided to switch over to PostgreSQL for performance and feature flexibility.

But, oh no! My DQL queries immediately began throwing errors 😵‍💫. What went wrong? My custom DQL syntax was perfectly crafted for MySQL’s quirks and functions but was incompatible with PostgreSQL. The choice was now between two challenging paths:

Option 1: Revert back to MySQL to keep things safe.

But what if I wanted to share the project with a developer who preferred PostgreSQL?

Option 2: Rewrite my DQL to support PostgreSQL.

But, what if I needed to switch back to MySQL later? Or what if I used a tool that only supported MySQL?

Choosing between these wasn’t easy—both options could lock me into a single database environment, limiting flexibility in future tech choices. So, I decided to take a different approach and created a solution to dynamically handle database-specific queries in a clean, reusable way.

Introducing DoctrineExpression

DoctrineExpression is a PHP library designed to enable cross-platform, database-agnostic DQL and SQL queries in Symfony or any project that utilizes doctrine. With DoctrineExpression, you can define custom syntax for each database platform (MySQL, PostgreSQL, SQLite, etc.), and it will select the correct expression based on the current database driver. It works like this:

Define Multiple Expressions: Write different syntax for each database driver, specifying unique queries that match each platform’s functions and quirks.
Automatic Driver Detection: DoctrineExpression checks the Doctrine platform in use, then automatically applies the correct syntax for MySQL, PostgreSQL, or any other supported database.
Future-Proof Flexibility: By allowing you to switch databases easily, DoctrineExpression future-proofs your code, ensuring that you can support multiple databases without extensive rewrites.

Now, with DoctrineExpression, I have the flexibility to use either MySQL or PostgreSQL (or even SQLite), keeping my code clean and maintainable. I can switch platforms based on project requirements, team preferences, or performance considerations without worrying about refactoring every custom query.

How DoctrineExpression Solves the Problem

Let’s look at a simple example where we need to retrieve users who registered within the last 24 hours. This is often handled differently in MySQL and PostgreSQL.

Without DoctrineExpression

MySQL: Uses DATE_SUB(NOW(), INTERVAL 1 DAY) to find records within the last 24 hours.
PostgreSQL: Uses NOW() - INTERVAL '1 day' for the same query.

Here’s how you might write these separately without DoctrineExpression:

// MySQL Query
$mysqlQuery = $entityManager->createQuery(
    "SELECT u FROM App\Entity\User u WHERE u.registeredAt > DATE_SUB(NOW(), INTERVAL 1 DAY)"
);

If you were using PostgreSQL, you would write in this format:

// PostgreSQL Query
$postgresQuery = $entityManager->createQuery(
    "SELECT u FROM App\Entity\User u WHERE u.registeredAt > NOW() - INTERVAL '1 day'"
);

If you switch databases, you'll need to modify this code, which is inconvenient and error-prone.

With DoctrineExpression

With DoctrineExpression, you define both syntaxes and let the library handle the rest:

use Ucscode\DoctrineExpression\DoctrineExpression;
use Ucscode\DoctrineExpression\DriverEnum;

// Create an expression instance with an EntityManager argument
$expression = new DoctrineExpression($entityManager);

// Registration S/DQL for varying database
$expression
    ->defineQuery(DriverEnum::PDO_MYSQL, function($entityManager) {
        return $entityManager->createQuery(
            "SELECT u FROM App\Entity\User u WHERE u.registeredAt > DATE_SUB(NOW(), INTERVAL 1 DAY)"
        );
    })
    ->defineQuery(DriverEnum::PDO_PGSQL, function($entityManager) {
        return $entityManager->createQuery(
            "SELECT u FROM App\Entity\User u WHERE u.registeredAt > NOW() - INTERVAL '1 day'"
        );
    });

// Fet any of the defined query based on the active doctine driver being used
$query = $expression->getCompatibleResult();

Now, DoctrineExpression checks the database platform in use and dynamically inserts the correct syntax for the current environment. It doesn't matter anymore you’re using MySQL or PostgreSQL, it will select the correct expression, saving you from having to modify your queries every time you switch platforms and also removes the boilerplate of using if-else repeatedly

In Conclusion:

DoctrineExpression saves time and effort by allowing you to use different databases without rewriting your queries. It’s particularly useful in containerized or multi-environment projects where you need to use custom syntax but database preferences may change depending on deployment needs or team familiarity. Give it a try, and let me know how it works for you!
