For years, Turbo relied on regex patterns to analyze code before inserting logs. It worked well, until it didn't. Complex codebases, deeply nested expressions, and modern JavaScript patterns constantly pushed regex to its limits.

From the start of 2025, the mission was clear: make Turbo more reliable when inserting logs, regardless of code complexity. This meant moving beyond pattern matching to true semantic code understanding. After months of intensive development, research, and testing, we finally shipped the Full AST Engine in July.

The engine was completely rebuilt from the ground up using Abstract Syntax Trees (AST), representing a fundamental shift from text pattern matching to semantic code understanding. The transformation was dramatic—vastly more sophisticated, comprehensively tested, and built to handle every edge case with surgical precision.

Then in October, we took it further by migrating from TypeScript's AST compiler to the lightweight Acorn parser. Same precision, dramatically better performance—the extension became a fraction of its original size with nearly instant activation. Your VS Code now starts faster than ever.

This foundation made everything else possible. Without AST precision, neither Pro's workspace management nor PHP support could exist at the quality level users deserve.

In June, Turbo PRO officially launched, transforming Turbo from a log insertion tool into a complete workspace debugging platform. What started as a sustainability move became something far more ambitious: a reimagining of how developers manage logs across entire projects.

The core innovation was the Tree Panel View, a native VS Code panel showing every log across your workspace, organized by file and line number. But that was just the beginning. Throughout 2025, Pro evolved into the ultimate workspace debugging companion:

Pro introduced a lifetime license model: pay once, own forever, use on up to 5 machines. No subscriptions, no recurring fees, just permanent access to all future updates. This sustainable model funds serious R&D while respecting developers' budgets.

By December, Pro had become the ultimate workspace log manager, helping developers manage logs at scale whether they have 100 or 1000 statements across their codebase. The free version remains fully available. Pro simply adds industrial-strength management for teams and large projects.

In November, Turbo expanded beyond JavaScript and TypeScript for the first time, adding comprehensive PHP support to Turbo PRO. This milestone proved Turbo's architecture could scale to multiple languages while maintaining the same quality and precision users expect.

PHP powers a massive portion of the web—WordPress, Laravel, Symfony, Drupal, and countless enterprise systems. Yet PHP developers have long lacked the sophisticated debugging tooling available in JavaScript ecosystems. Turbo PRO bridges that gap with full AST-powered intelligence: native PHP functions (var_dump, print_r, error_log), Pro panel integration for seamless full-stack debugging, and all the workspace management features JavaScript developers already enjoy.

PHP support validated the strategic vision that Turbo is becoming a universal debugging platform, not just a JavaScript tool. The AST foundation built earlier in the year made this expansion possible. This marks the beginning of Turbo's evolution into a true polyglot debugging assistant. The foundation is proven, the architecture scales, and the path forward is clear.
