v0.4.4 — Beyond parity (142 HTTP endpoints)

5 features that competitors don't have:

Action Caching

/cache/set?key=login_btn&ref=e3&action=click → repeated workflows skip LLM inference. Subsequent runs cost ~$0.

Set-of-Marks Screenshot

/screenshot/som → screenshot with numbered red bounding boxes on interactive elements. Vision models (GPT-4V, Claude) reference elements by number.

Hybrid Snapshot

/snapshot?include_screenshot=true → a11y tree + base64 screenshot in one call. Saves a round-trip for multimodal agents.

Smart Diff

/snapshot/changes → only what changed since last snapshot. 10-100x fewer tokens than full re-snapshot.

Recording Export

/recording/export → recorded actions as replayable /batch JSON. Record once, replay deterministically.

v0.4.3 — Full agent-browser parity (135 HTTP endpoints)

48 new endpoints since v0.4.2, closing every feature gap with agent-browser and browser-use.

Highlights

• POST /batch — multi-command execution in one HTTP call
• Enhanced /wait — text, URL pattern, networkidle, visibility, JS function conditions
• Semantic locators — /find-element?text=Submit / ?role=button / ?label=Email
• /page/state — 44x lighter than full snapshot (48 vs 2,124 tokens)
• Element state — /element/state?check=visible for quick boolean queries
• Dialog handling — auto-accept/dismiss JS dialogs
• Mouse/touch — move, down, up, wheel, tap, swipe
• Clipboard — read/write
• React inspection — component tree, props/state, render tracking, Suspense
• Core Web Vitals — LCP, CLS, FID, TTFB, FCP, domInteractive
• Recording — record/replay user actions
• Emulation — timezone, locale, permissions override
• Form ops — clear, selectall, setvalue, multiselect
• More — boundingbox, getattribute, inputvalue, pushstate, bringtofront, frame/mainframe, addstyle, expose, download, diff/url

Token efficiency

• 7-12% fewer tokens than agent-browser on real pages
• @e0 refs (3 chars) vs [ref=e0] (9 chars)

v0.4.2 — React-compatible click + type/fill

Fixes

• React/Vue click compatibility — click, check, and uncheck actions now use CDP Input.dispatchMouseEvent (mousePressed/mouseReleased) instead of DOM .click(), producing trusted isTrusted:true events that React 18/19 event delegation recognizes (#164)
• React/Vue type/fill compatibility — type and fill actions now use per-character CDP Input.dispatchKeyEvent instead of setting target.value directly, so React controlled inputs fire onChange correctly (#164)
• Click coordinate bug — fixed JS operator precedence in bounding-rect center calculation
• Server type/fill default — realistic mode (CDP key events) is now the default for the HTTP server /action endpoint

Testing

• React 18 e2e test fixture for validating form fill + click against controlled components

v0.4.1

Release and install fixes

• Installer parsing fix — Adds --color=never to installer grep calls so ANSI escapes do not corrupt macOS sed parsing.
• README install polish — Moves the copyable install command and direct download links to the top of the README for easier release consumption.
• Release metadata sync — Runtime version string and npm package metadata aligned for the v0.4.1 patch release.

macOS assets in this release are signed with Developer ID Application: Rachit Pradhan (WWP9DLJ27P) and notarized via the local notary-local keychain profile.

v0.4.0 — 2026-05-22

kuri-browser — Standalone Browser Engine

• Native rendering engine — Full DOM tree, CSS cascade with layout/paint, real <table> layout, font shorthands (border/padding/margin/list-style), text metrics with per-character glyph widths calibrated against headless Chrome
• QuickJS runtime — JavaScript evaluation, fetch/XHR bridge, cookie-aware navigation state, form extraction, session-backed form submission, HAR capture for browser flows
• CDP server — Minimal CDP WebSocket router, CDP discovery server, compressed screenshot fallback, parsed DOM selectors
• Agent actions — Click, type, snap, scroll, navigate, eval, back/forward via CDP-compatible commands
• Parity tracking — Pixel parity benchmark harness vs Chrome (98.45% wrapper / 86.37% direct)

kuri-mobile — iOS + Android Device Control

• Zig-native device automation — Driverless: no on-device app, no Bun, no Gradle, no Xcode-time builds
• Android — ADB host protocol, XML UI tree parser, device listing
• iOS — Simulator control via xcrun simctl, real device listing via usbmuxd, CGEvent-based tap/swipe/pan/type into Simulator.app

Server

• Bearer-token API auth — All endpoints protected by configurable bearer token
• Signal-safe Chrome lifecycle — Chrome process shutdown uses signal-safe paths

macOS assets in this release are locally signed with a Developer ID certificate (not notarized).

v0.3.3

Fixes

• Auth profile reliability: macOS keychain-backed auth profiles now resolve security correctly, and profile metadata round-trips escaped JSON safely.
• Session persistence safety: bridge export/import now uses real JSON serialization/parsing instead of fragile string scanning.
• Redirect and localhost hardening: URL validation now normalizes localhost aliases and re-validates redirect hops in both HTTP fetch paths.
• CDP stability: stale buffered events no longer satisfy later waitForEvent() calls, and unsupported external CDP endpoint shapes are rejected up front.
• Packaging correctness: HAR status/duration output is fixed, Chrome binary discovery checks PATH, and the npm installer rejects unsupported platforms instead of treating Windows as Linux.
• CLI behavior: kuri --help and kuri --version now exit immediately instead of booting a new kuri server.

Release assets

• aarch64-macos and x86_64-macos tarballs were rebuilt from f0ab19b and re-notarized for this release refresh.
• Apple notarization accepted:
  • aarch64-macos: d5bdc803-7de2-4653-bec2-2a1377a8707a
  • x86_64-macos: d76a977e-e310-44f9-813b-24e5d06b7650
• Stable installer and manifest continue to be served from release-channel.

v0.3.2

Release channel

• Added a self-managed stable release channel backed by the release-channel branch.
• Installers and manifests can resolve binaries directly without depending on a GitHub Release object.
• Raw GitHub asset URLs are documented in the README and manifest.

macOS distribution

• aarch64-macos and x86_64-macos tarballs are signed and notarized.
• Notarization submissions were accepted by Apple for both macOS builds.
