The 2026 Developer Stack
VS Code remains the dominant IDE, but the *way* we use it has changed. It's no longer just a text editor; it's an AI orchestrator.
### 1. Copilot Sentinel (Security)
In 2026, data sovereignty is everything. Sentinel audits your AI prompts before they leave the IDE to ensure no API keys or PII are leaked.
### 2. Mermaid Live Edit
Documentation-as-code is the standard. This extension renders Mermaid diagrams in real-time as you type them in your README.
### 3. Tailwind v4 Lens
With Tailwind 4's multi-layered JIT, you need a visual tool to see how styles are merging. This lens provides a "calculated view" of any class.
### 4. GitGraph Pro
Visualizing recursive merges and agent-driven commits is complex. GitGraph clarifies the history of even the most messy repositories.
### 5. DevUtility Sidecar
The ultimate companion. While not an extension per se, pinning DevUtility Hub to your sidebar gives you instant access to 128+ private tools like JSON Formatters and JWT Decoders that shouldn't be handled by cloud-syncing extensions.
