agentic browsers.

Skylark is an agentic, cross-platform desktop browser built in Rust. A real browser with an AI agent that reads the page, clicks, fills, and does the task for you. Bring your own model. Script it from the shell. See every step.

What makes Skylark different

A real browser, not a chat bolted onto one. Three things set Skylark apart, then a few more that make it sing.

  • /open:

    Open, not a walled garden

    Skills are plain text. Read them, edit them, put them in Git. Sites can ship their own, so the web starts to automate itself. Skylark is an agent-controllable surface, not just an agent glued to a browser.

  • /cli:

    Developer-native to the bone

    A real CLI drives the browser. Run a skill, pipe in a one-shot headless task, or hand a turn to opencode, Claude Code, or Gemini CLI. Skills move between the terminal, the command palette, and right-click.

  • /trust:

    Glass-box by default

    Every action is visible, replayable, and interruptible. The agent can use your saved logins and cards to act, but it structurally never sees their values. Cross-site autofill is blocked so a prompt cannot exfiltrate them.

  • /agent:

    An agent that reads the page

    It reads the DOM, clicks, scrolls, waits, fills, screenshots, and follows links. Then it chats with you about the page and your open tabs, with the full context, not a guess.

  • /skill:

    Skills that load per site

    Open SKILL.md skills, versioned in Git. Skylark finds the right one for the site you are on. Sites publish their own via /.well-known/agents.json, with llms.txt as a graceful fallback.

  • /mcp:

    MCP, in and out

    An in-process MCP server exposes your tabs, DOM, history, and actions as tools that other agents can drive. An MCP client lets your workflows span the web and your own tools.

/how:

Up and running in four steps

From download to a working agent in a few minutes.

  1. 01 /install:

    Download and open Skylark

    Grab the macOS build and drop it in Applications. It opens like any browser, with real tabs and real rendering.

  2. 02 /connect:

    Bring your own model

    Add your key at skylark://settings/ai. Anthropic, OpenAI, OpenRouter, or a local agent. Nothing leaves your machine unless you ask it to.

  3. 03 /task:

    Give it a task

    Ask in plain language. Prep for meetings, draft replies, catch up on threads, fill the long form, generate the report.

  4. 04 /steer:

    Watch every step

    Each action shows up as it happens. Pause it, interrupt it, or set a stop-before boundary. You are always in the loop.

/agent:

The agent works next to the page

Skylark is a real browser with a side panel companion. The agent and the page share one window, so context never gets lost in a separate tab.

  • Reads the DOM and your open tabs, with the full picture.
  • Clicks, fills, scrolls, waits, screenshots, and follows links.
  • Every action shows up live. Pause or interrupt at any point.

/trust:

Trust is a feature, not a footnote

Power without panic. Skylark is built so the agent can act, and you stay in control.

  • /see:

    Glass-box execution

    Every action is visible, replayable, and interruptible. Nothing happens in the dark.

  • /isolate:

    Credentials never exposed

    The agent can act with your saved logins and cards, but it structurally cannot read their values.

  • /block:

    Cross-site autofill blocked

    A prompt on one page cannot pull credentials meant for another, so injection cannot exfiltrate them.

  • /stop:

    Stop-before boundaries

    Set a natural-language limit like "stop before paying" and Skylark pauses for your call.
