Building a Free Instagram Editor with Svelte 5, WASM, & Llama 3.1

Hello DEV community! 👋 Building a web-based graphic editor usually means wrestling with HTML5 Canvas or heavy WebGL libraries. But what if you could bypass Canvas entirely, manipulate the DOM directly with pure CSS, wrap it in blazing-fast Svelte 5 runes, and inject local WASM for background removal? Today, I want to share the technical journey of building SMM Turbo - a completely free, in-browse...

Best Apideck Alternatives: Unified API Platforms

If you have ever tried to build product integrations yourself, you know what a time sink it is. OAuth pains. API docs that never match what the response actually looks like. Testing every weird edge case. Most teams just want something that works, so their engineers can focus on things customers notice. That is why unified API platforms like Apideck have gotten so popular. They save massive eng...

JSON Web Tokens (JWT): Deep Dive into Design, Security Risks and Real-World Failures

JWT (JSON Web Tokens) have become a default choice for authentication and authorisation in modern systems. They are widely adopted because they are: Stateless Scalable Easy to integrate across services But in real-world environments, especially distributed systems, JWT often introduces subtle security risks that are not immediately visible. Most JWT implementations are cryptographically cor...

What if your authoritative DNS server *was* a Git repository?

DNS has no git. I built one. This is a working prototype, not a finished product. The point of the post is to show that a long-standing gap in how DNS handles its own state is real, and that closing it is more tractable than it looks. The 2 a.m. question Pick any on-call channel. Wait long enough. Eventually someone types: "What did api.checkout.acme.com point to ten minutes ago?...

The APIs Quietly Powering the Products You Use Every Day

When users interact with a product, they see the surface: the interface, the animations, the data that appears in front of them. What they do not see is the layer underneath — the network of APIs that make the product work. The payment processor that handles the transaction. The mapping service that plots the route. The AI model that generates the response. The identity provider that authenticates...

The Bucket You Deleted is Still in Your DNS: S3 Bucket Takeover at Bime

In 2016, a researcher found that a2.bime.io had a CNAME record pointing to bimeio.s3.amazonaws.com. The bucket bimeio did not exist. It was not owned by Bime. It was not owned by anyone. The researcher created the bucket in their own AWS account. a2.bime.io was now serving their content — under Bime's domain, with Bime's SSL certificate, trusted by Bime's users. This is HackerOne #121461. The fi...

What Does "Identity" Actually Mean on a Blockchain?

If you've been writing code for a while, you've probably used SSH keys. You generate a key pair, drop the public key on a server, and from that point on, you prove who you are by holding the private key. No username, no password reset. You either have the key, or you don't Solana identity works on the same principle: you have the key, or you don't — except that, instead of a single server, it's t...

The Model Context Protocol (MCP) standard is becoming the default way to expose tools to LLMs in 2026. Anthropic, OpenAI, and every major editor vendor — Cursor, Cline, Continue, Windsurf — now ship with MCP support. If you have any API or scraper, MCP-ifying it is a free distribution channel into every AI client on the market. I had 12 web scrapers running on Apify Store. Last weekend I bundled ...
