Production Agent Workflows

v2026.08

Reusable templates, durable results, and more efficient browser sessions

2026/08/21

Repeatable browser automation at scale

  • Added Chromium and Moli browser choices when creating sessions. Moli uses the stable SDK/API value light and is optimized for lightweight agent browsing.
  • Added environment-aware browser task templates with reusable agent instructions.
  • Enabled recording by default and strengthened cross-region replay and download persistence.
  • Improved browser efficiency and resource use for larger-scale session workloads.

Agent Access and Faster Startup

v2026.07

Simpler agent onboarding with reusable contexts and warm browser capacity

2026/07/31

Faster paths from prompt to browser

  • Added agent-specific setup prompts, guided quick starts, and secure Browser CLI sign-in.
  • Expanded reusable contexts with descriptions, regions, forks, and media storage controls.
  • Reduced startup waiting through prewarmed capacity and readiness improvements.

Browser CLI for AI Agents

v2026.06

A structured command-line browser interface designed for autonomous agents

2026/06/30

Agent-native browser operations

  • Introduced Browser CLI with semantic navigation, form, wait, storage, and diagnostic actions.
  • Added reusable context selection, secure sign-in, and machine-readable JSON output.
  • Packaged agent guidance, environment checks, and quick-start workflows for reliable first-run setup.

Multi-Region Access and Security

v2026.05

Region-aware SDKs and safer access for distributed browser workloads

2026/05/31

Secure multi-region sessions

  • Added region discovery and automatic region selection to the JavaScript and Python SDKs.
  • Introduced integrated sign-in, custom browser images, and configurable session window sizes.
  • Strengthened download access and stored-session data protection.

Async Sessions and Replay Controls

v2026.04

A non-blocking session lifecycle with richer context and recording controls

2026/04/30

Scalable session lifecycle

  • Made asynchronous session creation with readiness polling the default SDK workflow.
  • Added browser context forks and session target discovery.
  • Introduced explicit recording controls and activity-aware session timeouts.

Extensible Session Runtime

v2026.03

Extensions, downloads, and per-session proxy support arrive across the platform

2026/03/31

More capable browser sessions

  • Added extension mounting for customized browser workflows.
  • Introduced session download storage and retrieval APIs.
  • Added per-session proxy support and aligned the capabilities across the JavaScript and Python SDKs.

Reliable Long-Lived Automation

v2026.02

Keep-alive controls and reliability fixes for durable browser workflows

2026/02/28

Resilient session continuity

  • Expanded context keep-alive controls for long-running automation.
  • Fixed finalization and deletion timing issues that could leave stale browser sessions.
  • Improved diagnostic visibility so failed browser operations can be resolved faster.

Persistent Browser Contexts

v2026.01

Reusable browser identity and user data across multiple sessions

2026/01/31

Durable browser state

  • Added browser context creation, listing, inspection, and deletion APIs.
  • Enabled cookies, profiles, and browser state to be reused across sessions.
  • Added usage limits, conflict handling, and safer deletion for more predictable context management.

Session Reliability Improvements

v2025.12

Faster startup, safer timeouts, and more dependable cleanup

2025/12/31

Reliability across the session lifecycle

  • Improved browser readiness checks and startup reliability for parallel workloads.
  • Added more predictable session timeout behavior.
  • Fixed validation and cleanup edge cases that could leave sessions unavailable or unfinished.

Session History and Resource Insights

v2025.11

A unified operational view of active and completed browser sessions

2025/11/30

Observable session operations

  • Unified active and historical sessions behind a paginated session interface.
  • Added historical resource usage, peak memory, and network bandwidth measurements.
  • Introduced controlled custom browser image selection for specialized workloads.

Flexible Browser Modes

v2025.10

Multiple browser modes for different automation workload requirements

2025/10/31

The right browser mode for each task

  • Added full-featured and lightweight browser modes for different automation workloads.
