Hey everyone. We held a bunch of changes for [Launch Week v3](https://steel.dev/launch-week), so this one is larger than usual: Stealth Browser, Dedicated IPs, Rust and Go SDKs, Atlas, pricing updates, and new cookbook recipes.

### ⭐ New

#### Stealth Browser

Stealth Browser is live for enterprise customers. It is Steel's Chromium fork for agent sessions, with the browser profile applied at process startup before page JavaScript reads browser surfaces.

#### Dedicated IPs for sessions

Steel now supports dedicated IPs for browser sessions, including session-level IP selection, supported location selection in the app, and updated docs and pricing details for the new networking option.

#### Rust and Go SDK support in the docs and cookbook

Steel's docs and cookbook now cover the [Rust SDK](https://github.com/steel-dev/steel-rust) and [Go SDK](https://github.com/steel-dev/steel-go), with browser, scrape, computer-use, and framework examples across both languages.

#### Atlas

[Atlas](https://github.com/steel-dev/atlas) is a new open-source research harness (`@steel-dev/atlas`) for multi-agent browser research with an evidence ledger and optional claim verification.

### 🔧 Improvements

*   Pricing moved to Launch, Scale, and Enterprise on one metered model, with usage credits, top-ups, budget controls, project usage filtering, and clearer per-meter cost breakdowns.

*   Steel's CAPTCHA handling now supports PerimeterX press-and-hold challenges via CDP, with controls to disable autosolving for specific CAPTCHA types when needed.

*   The cookbook added new recipes for MCP servers and agent orchestration workflows with Trigger.dev, Restate, and Temporal.

*   The leaderboard added the DRACO deep research benchmark, new BrowseComp rows for Exa Agent and Perplexity Agent, and Atlas callouts on research benchmark pages.

### 🐛 Bug Fixes

*   Fixed cookbook language tabs so pages fall back to a valid default when a previously saved language is no longer available.

*   Fixed session creation failures in Steel Browser by falling back to relaxed fingerprint constraints when the bundled dataset lags the latest Chrome release.

*   Fixed browser log draining so large DuckDB write buffers no longer overflow during flushes, and updated managed-browser log handling to wait for logs to clear reliably.

*   Fixed managed-browser shutdown handling so ffmpeg exits gracefully during session teardown.

*   Corrected selected API request bodies so endpoints that do not require payloads are optional again.

*   Fixed Go and Rust browser examples in the cookbook so they run reliably against the live API.

### 🏡 Housekeeping

*   Infra added a provider-agnostic bare-metal provisioning layer, internal APT repository support, and Debian package publishing pipelines for host-native services used in Steel's next infrastructure stack 😱.
