Billy Enrizky Openbrowser AI Form Filling

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.

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="user@example.com")
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

Step 4 -- Handle dropdowns

Standard HTML select elements:

openbrowser-ai -c - <<'EOF'
await select_dropdown(index=12, text="United States")
EOF

To see available options first:

openbrowser-ai -c - <<'EOF'
options = await dropdown_options(index=12)
print(options)
EOF

Custom dropdown components:

openbrowser-ai -c - <<'EOF'
await evaluate("""
(function(){
  const select = document.querySelector("select#country");
  select.value = "US";
  select.dispatchEvent(new Event("change", { bubbles: true }));
})()
""")
EOF

Step 5 -- Handle checkboxes and radio buttons

openbrowser-ai -c - <<'EOF'
await click(index=15)  # Click checkbox/radio

# Verify state
checked = await evaluate("""document.querySelector("input[name=agree]").checked""")
print(f"Checkbox checked: {checked}")
EOF

Step 6 -- Submit the form

openbrowser-ai -c - <<'EOF'
await click(index=20)  # Click submit button
await wait(2)

# Verify submission
state = await browser.get_browser_state_summary()
print(f"After submit: {state.url}")
EOF

Or submit via JavaScript:

openbrowser-ai -c - <<'EOF'
await evaluate("document.querySelector(\"form\").submit()")
EOF

Step 7 -- Verify submission result

openbrowser-ai -c - <<'EOF'
# Check for success/error messages
result = await evaluate("""
(function(){
  const success = document.querySelector(".success, .alert-success, [role=\"alert\"]");
  const error = document.querySelector(".error, .alert-danger, .validation-error");
  return {
    success: success?.textContent?.trim(),
    error: error?.textContent?.trim(),
    url: window.location.href
  };
})()
""")
print(result)
EOF

Step 8 -- Handle multi-step forms

openbrowser-ai -c - <<'EOF'
for step in range(1, 5):
    # Discover fields for current step
    state = await browser.get_browser_state_summary()
    print(f"Step {step}: {len(state.dom_state.selector_map)} elements")

    # Fill fields (indices vary per step)
    # ... fill fields here ...

    # Click Next/Continue
    # Find the next button
    for idx, el in state.dom_state.selector_map.items():
        text = el.get_all_children_text(max_depth=1).lower()
        if "next" in text or "continue" in text:
            await click(index=idx)
            await wait(2)
            break
EOF

Tips

• Code is piped via stdin using heredoc (-c - <<'EOF'), so all Python syntax works without shell escaping issues.
• Always discover fields with browser.get_browser_state_summary() before typing -- do not guess element indices.
• For sensitive data (passwords, tokens), confirm with the user before entering values.
• Use evaluate() to bypass custom components that do not respond to standard click/type.
• Variables persist between -c calls while the daemon is running, so you can store field indices in one call and use them in the next.
• Check for CAPTCHA or bot detection; notify the user if manual intervention is needed.
