Hosted pages now prerender from the same Solid component tree used in the browser and hydrate the existing DOM. The Cloudflare build produces 27 hydratable routes and checks the hydration script and CSP in its runtime smoke.
Updated the hosted app to solid-js@2.0.0-rc.11, @solidjs/web@2.0.0-rc.11, and @solidjs/vite-plugin@3.0.0-next.46. Fixed the transparency checker so file selection and drop handlers remain active after Safari hydration.
Expanded bgcut.dev with Guides, Tools, and Compare pages, page-specific search metadata, and current sitemap lastmod dates.
Migrated the internal Effect dependency to effect@4.0.0 and added a repository check that rejects removed Effect APIs and obsolete version references.
No public Node API, CLI command syntax, background-removal model, or inference algorithm changed in 0.6.1.
0.6.0
Reworked the Node API around bgcut(). The returned instance owns removeBackground(), removeMany(), and close(), so single-image and multi-image work use one API object and one runtime lifecycle. Migrating from 0.5.x means replacing the top-level removeBackground() and createBgcut() exports with bgcut(); reusable .remove() calls become .removeBackground().
Added removeMany() for files, directories, iterables, and async iterables. Directory scans are recursive by default, processing is sequential, results are yielded one at a time, and one failed image does not stop later inputs.
Expanded the CLI to accept several image paths or directories. The CLI uses the same public bgcut object API, and batch --output paths preserve nested directory structure.
Reworked the hosted Node API documentation, README, llms.txt, TypeScript declarations, and packaged agent skill around the new object API, with separate examples for single images, multiple images, directory input, lifecycle, engines, and errors.
Added copy controls and lightweight syntax highlighting to hosted code examples, plus direct agent links to /llms.txt, the packaged skill, and Node API types. Successful copies now show a themed green check.
Fixed hosted layout details. Route changes keep header geometry stable, changelog dates align separately from versions, the homepage intro is smaller, the theme moon is centered, model artifacts use a comparison table, and component colors use semantic theme tokens.
0.5.0
Safari WebGPU now uses a reusable no-capture ONNX Runtime session and selects the validated internal-FP16 BiRefNet artifact when the WebGPU device exposes shader-f16. Safari without that feature, Chromium-family WebGPU, browser WebAssembly, and native Node/CLI keep FP32.
On an Apple M3 Pro with Safari 26.3, the process-isolated six-image gate moved the pooled warm inference median from 1,101 ms with FP32 to 627.5 ms with FP16, a 43.0% reduction. The pooled warm total median moved from 1,309 ms to 873.5 ms, a 33.3% reduction.
The Safari FP16 artifact is 98,572,669 bytes, compared with 195,872,736 bytes for FP32. Public model input and output remain FP32.
In the same six-image gate, aggregate MAE moved from 0.02255466 to 0.02200792, MSE from 0.01933876 to 0.01876192, IoU from 0.96425259 to 0.96511045, and F1 from 0.98180101 to 0.98224550. These measurements are specific to that hardware and benchmark set.
Added persistent light and dark site themes backed by semantic color tokens.
Added repeatable benchmark commands for bgcut timing and output-quality scoring, with a documented comparison protocol.
Simplified the Documentation and Changelog layout around the permanent left rail. The hosted changelog now lists only full stable releases.
0.4.0
Validated the installed package end to end across the one-shot Node API, reusable WebGPU sessions, public error contract, CLI inference, packaged local app, health route, and model delivery.
Added removeBackground(input, options?) for one-shot Node.js removal while keeping createBgcut() for reusable sessions and batch work.
Added the public BgcutError contract with stable model, engine, input, inference, output, and closed codes. Malformed image bytes reach callers through the same public error type.
Added the shared Documentation and Changelog reference layout, route metadata, search discovery files, WCAG AA secondary text contrast, static-asset security headers, and the 75 ms fade-out plus 75 ms fade-in title handoff.
Updated Cloudflare runtime deployment so unchanged R2 assets skip uploads, changed or missing runtime objects retry transient failures, and deployment verifies the live runtime routes.
0.3.2
Reorganized the repository around explicit app, browser, CLI, Node, native, shared, Worker, documentation, and tooling directories while keeping the published CLI and Node API behavior intact.
Split the browser application into focused pages, navigation, and shared site chrome. The documentation scroll tracking follows the reader in the upper part of the viewport.
Moved engineering, operations, roadmap, model, package, Cloudflare, and brand files into clearer locations and added repository-layout checks to prevent the old paths from returning.
Kept the vendored anti-slop rules current and enforced through oxlint.
Removed the obsolete Cloudflare observability setting that Wrangler no longer supports and aligned the runtime smoke path with Wrangler 4.135.0.
No background-removal model, inference algorithm, CLI command syntax, Node API contract, or packaged local-app workflow changed in this release.
0.3.1
Validated the installed package across the packaged local shell, image removal, comparison slider, clipboard and paste actions, keyboard shortcuts, file download, health endpoint, and local route redirects.
The packaged local app now shows only the bgcut brand and removal workflow. Docs, GitHub navigation, Privacy, Terms, and the site footer remain on bgcut.dev.
Non-root local app routes redirect to / while /health, /models/..., and /runtime/... remain available to the packaged app.
bgcut.dev remains the full hosted site with Docs and GitHub navigation, Privacy and Terms pages, footer links, and section-aware documentation navigation.
No background-removal model, inference algorithm, CLI command syntax, or Node API contract changed in this release.
0.3.0
Validated npm installation, the packaged local UI, result actions, the headless CLI, and serve --json in a clean consumer environment.
Added the packaged local web app. bgcut or bgcut serve starts the browser UI on loopback with JSON startup discovery, local health checks, the validated model route, and installed ONNX Runtime assets.
Published the CLI as a Node executable so npm and npx users do not need Bun.
Added the reusable createBgcut() Node API with automatic, GPU, and CPU engine selection plus ONNX Runtime session reuse across removals.
Shared one validated native model cache across the local app, CLI, and Node API while keeping the large BiRefNet model out of the npm tarball.
Added browser keyboard shortcuts for New Image, Copy, Download, and Redo, plus native left and right keyboard control for the comparison slider.
Expanded the packaged agent skill, README, release instructions, package metadata, and smoke coverage to match the 0.3 public behavior.
0.2.1
Replaced the renderer-dependent README icon and title alignment with one pre-aligned bgcut lockup so the brand header renders consistently on GitHub and npm.
No runtime, inference, CLI, model, or web-app behavior changed.
0.2.0
Shipped bgcut.dev on Cloudflare Workers with the BiRefNet model and ONNX Runtime files served from private R2 through same-origin routes.
Added Cloudflare deployment checks for the Worker, model route, ONNX Runtime routes, security headers, and local R2 setup.
Added the bgcut brand mark to the app header, favicon, touch icon, web app icons, manifest, social preview, repository README, and npm-facing README.
Added canonical URLs, route metadata, Open Graph and Twitter metadata, robots.txt, sitemap.xml, and structured metadata for bgcut.dev.
Updated npm-facing documentation and the bundled agent skill to use the stable install commands.
