Private by design. Built to stay out of your way.
Delta Suite handles the complex patching algorithms locally on your machine. Generate lean, secure updates without uploading gigabytes of assets to the cloud or forcing your users into proprietary storefronts.
Offline Processing
Keep your unreleased builds entirely on your own hardware. Delta Suite processes your files locally, guaranteeing your proprietary source code and assets never touch a remote server.
Cryptographic Validation
Delta Suite strictly verifies the source file before patching, and validates the output after patching using your choice of Blake3 or SHA-256 hashes.
Keyboard-First Workflow
Delta Suite is built with a meticulously designed, shortcut-driven GUI. Navigate, configure algorithms, and execute massive local bulk-patches entirely from your keyboard at lightning speed.
Standalone Installers
Wrap your patches into a single, lightweight executable. Users just double-click the file, and the installer locates the target and applies the update locally—no external software required.
Version Chaining
Avoid massive redownloads for missed updates. The engine natively chains intermediate patches together, seamlessly upgrading a user from version 1 to 3 by combining the required steps instantly.
File-by-File Analytics
Delta Suite lets you drill down into specific directories to see byte-level comparisons, and exact diff metrics between your current and previous builds.
Under the Hood: Architecture & DPAT
Delta Suite pairs a fluid, cross-platform Flutter GUI with a relentlessly optimized Rust engine. We engineered a robust, standalone patch format designed to guarantee integrity and support seamless automation.
- Flutter Frontend: The desktop GUI is built with Flutter, ensuring the interface behaves consistently across Windows, macOS, and Linux.
- Rust Backend: Handles the core processing. It safely routes file
streams through
HDiffPatch,xdelta3, orbsdiffwhile strictly managing memory, ensuring gigabyte-scale files don't crash your machine. - Cryptographic Agility: Choose between Blake3 for maximum throughput or SHA-256 for strict compliance. Patches embed 64 bytes of signatures to natively execute pre- and post-flight validation.
- Embedded Metadata: Contains target filename hints, relative directory structures, and file permissions (like Unix executable flags) to ensure the output perfectly mirrors the source.
- Zero Vendor Lock-in: The DPAT format is completely transparent. You can
unpack any generated DPAT file back into its raw
algorithmic patch (raw
hdiff,xdelta3, etc.) at any time, ensuring you are never trapped in a proprietary ecosystem.
Built for studio-scale workflows.
Gain absolute control over your build architecture. Delta Suite Studio provides the advanced automation, bulk processing, and deep visual analytics required for massive, multi-gigabyte asset pipelines.
- Export to CI/CD: Visually configure patch settings, then export exact Bash scripts with one click.
- Batch Processing: Bulk process entire directories of massive multi-gigabyte game assets or databases effortlessly.
- Isolate Bloat Culprits: Drill down into specific directories and visualize exact byte-level changes per file to optimize your packaging strategy.
- Smart Web Installers: Provide your update URLs, and the stub automatically calculates the most efficient upgrade path—intelligently choosing between chaining intermediate patches or downloading the full release.

The Roadmap
We're taking care of the heavy lifting so you don't have to. Here is what's on the horizon for Delta Suite.
Headless CLI Tool
Integrate Delta Suite directly into your automated workflows. We are building a headless CLI tool so you can generate patches natively within GitHub Actions, GitLab CI, or custom build pipelines.
Streamed Patching
Apply patches on the fly directly from an HTTP network stream. Zero disk overhead for the patch file itself—decompress and apply simultaneously to save local storage and speed up updates.
xdelta3 Support
Expand your algorithmic choices. We are adding native support for the industry-standard xdelta3 engine alongside our HDiffPatch core, giving you maximum flexibility for different data types.
Differential Rollbacks
Reverse Patching. Sometimes updates break things. We are building the ability to generate 'rollback' patches that reverse a target file to its previous state with minimal payload sizes.
DPAT Metadata Container
We are building a robust, variable-length metadata layer into the DPAT format. Using highly efficient serialization, patches will natively store file paths, granular permissions, and complex directory structures.
