Form Filling

Automate filling web forms including login, registration, checkout, and multi-step form wizards using Python code execution.

All code runs via openbrowser-ai -c. The daemon starts automatically and persists variables across calls. All browser functions are async -- use await.

The CLI daemon also persists cookies and login state in ~/.config/openbrowser/profiles/daemon/storage_state.json, so authenticated sessions can be reused across later runs.

Setup

Before running, verify openbrowser-ai is installed:

openbrowser-ai --help

If not found, install:

# macOS/Linux
curl -fsSL https://raw.githubusercontent.com/billy-enrizky/openbrowser-ai/main/install.sh | sh

# Windows (PowerShell)
irm https://raw.githubusercontent.com/billy-enrizky/openbrowser-ai/main/install.ps1 | iex

Workflow

Step 1 -- Navigate to the form page

openbrowser-ai -c - <<'EOF'
await navigate("https://example.com/login")
state = await browser.get_browser_state_summary()
print(f"Page: {state.title} ({state.url})")
print(f"Interactive elements: {len(state.dom_state.selector_map)}")
EOF

Step 2 -- Discover form fields

openbrowser-ai -c - <<'EOF'
# List all interactive elements with their indices
state = await browser.get_browser_state_summary()
for index, element in state.dom_state.selector_map.items():
    tag = element.tag_name
    text = element.get_all_children_text(max_depth=2)[:60]
    placeholder = element.attributes.get("placeholder", "")
    input_type = element.attributes.get("type", "")
    name = element.attributes.get("name", "")
    print(f"[{index}] <{tag}> type={input_type} name={name} placeholder=\"{placeholder}\" text=\"{text}\"")
EOF

Step 3 -- Fill text inputs

openbrowser-ai -c - <<'EOF'
# Fill fields using their indices from Step 2
await input_text(index=5, text="[email protected]")
await input_text(index=7, text="secure-password")
EOF

For fields that need clearing first:

openbrowser-ai -c - <<'EOF'
await click(index=5)
await evaluate("document.activeElement.select()")
await input_text(index=5, text="new-value")
EOF
