Local by design
Processing happens in the Bun runtime on your device. Images never cross a web API or an account boundary.
Local-first image workflows
Make every image feel intentional.
Optimize, transform, and organize image batches with a calm desktop workflow or a predictable command line. Your files stay on your machine.
Example command: rastry run ./public --preset web. The dry run plans four files and completes without changing them.
Private by default. No account, upload, or telemetry is required to process an image.
A smaller, safer loop
The useful parts stay close to your files.
Rastry is built for developers, designers, and small teams who want repeatable image work without handing assets to a service.
Repeatable by default
Express a workflow as a versioned pipeline or a readable preset, then use the same rules from CLI or desktop.
Safe before fast
Every run starts with a plan. Outputs get a derived name, originals are protected, and conflicts are visible before writing.
Current foundation
Small surface. Real operations.
Rastry currently handles the formats and transformations that make up the everyday web-asset loop.
PNG · JPEG · WebP
Read the tradeoffs and use each format deliberately.
Explore formatsResize · crop · trim
Shape dimensions, remove transparent borders, and prepare assets for their destination.
Explore operationsWeb · ecommerce · social
Start with shipped recipes that map to real delivery contexts.
Explore presetsChoose your entry point
One engine, two ways to work.
The CLI and Desktop v0.2 use the same pipeline contract and safety rules. Choose the surface that fits the task.
CLI for scripts and agents
Plan a one-off conversion, run a preset over a folder, or capture a JSON summary for automation.

Select files or folders, configure operations, review the plan, then execute only after the output paths look right.

Trust is a feature
Nothing happens silently.
Rastry favors a visible, deterministic plan over a surprising shortcut.
- Dry-run first. See files, operations, output paths, and conflicts without writing.
- Originals stay intact. Outputs go to a chosen directory or use the
-rastrysuffix. - Batch failures are isolated. One bad input does not hide the rest of the summary.
- Telemetry is off. The product does not add analytics or uploads by default.
Maturity, made visible
Built in small, useful steps.
Rastry is foundation-stage software. The roadmap is a promise about sequence, not a claim that every item is shipped.
v0.1 · Foundations
Core, Bun.Image adapter, safe CLI, formats, operations, batches, and dry-run.
v0.2 · Desktop
Electrobun + React workflow with typed RPC, plan preview, progress, and summary.
v0.3 · Reuse
Local presets, import/export, execution history, and recipe documentation.
v0.4 · Integration
Explicit watch mode, installers, updates, and performance work.
