Key Features

Code Ingestion & Analysis

Ingest

Moderne builds Lossless Semantic Trees from your source code, providing a compiler-accurate, multi-language, and queryable representation of your codebase. This allows users to see the true shape of their estate before any changes are executed.

Lossless Semantic Tree (LST)

The Lossless Semantic Tree powers the entire platform, enabling semantic search across the estate and context resolution for coding agents. It serves as a foundational model for code change and intelligence, ensuring accuracy and consistency.

Code Change Execution

Run

Users can execute recipes from a comprehensive catalog or create custom recipes to apply deterministic changes across multiple repositories. The same recipe guarantees the same diff across every repository it touches, ensuring consistency.

Vulnerability Remediation

Moderne automates the fixing of CVEs and zero-day vulnerabilities directly at the source across all affected repositories. This proactive approach ensures that security issues are addressed comprehensively rather than just flagged.

Framework and App Modernization

The platform facilitates the modernization of frameworks and applications, allowing users to upgrade technologies like Spring and .NET version by version, including handling breaking changes that typically hinder upgrades.

Language Version Upgrades

Moderne supports upgrading programming languages such as Java, Kotlin, Python, C#, and JavaScript to their latest versions. This includes managing API changes and ensuring compatibility across services.

Dependency and EOL Hygiene

The platform helps replace end-of-life libraries and manage vulnerable transitive dependencies, ensuring that version drift across services is corrected and that the codebase remains secure and up-to-date.

Build and Config Migration

Moderne keeps build tools and CI configurations current, ensuring that boilerplate code does not hinder future upgrades. This includes managing configurations for tools like Maven, Gradle, and npm.

Review & Governance

Review

Users can browse results in the DevCenter, review every diff generated by the platform, and open pull requests in their source control management (SCM) system. No changes are merged until they receive explicit approval from developers.

Governance and Reporting

The DevCenter dashboards provide visibility into what changes occurred, where they happened, and the reasons behind them. Every recipe is reproducible, and all diffs are signed off before merging, ensuring accountability.

Agent Tools Integration

Trigrep

This feature offers symbol-aware, trigram-indexed search capabilities built from the Lossless Semantic Tree. It allows coding agents to locate every real occurrence of code across the estate in milliseconds, eliminating the need for follow-up reads.

Prethink

Prethink provides precomputed, compiler-accurate context, including architecture, dependencies, and code quality, ready before the coding agent session starts. This reduces the token tax on discovery for agents.

Recipes

Deterministic transformations that coding agents can call instead of making guesses. Each recipe is designed to apply the same edit across one repository or many, ensuring consistency and reliability.

Changelog

This feature provides a portfolio-wide view across every SCM, allowing for bulk approval, merging, and closing of changes. It ensures that agent-driven changes remain auditable and under control.
