## Which one, for what

### Pomerado (B)

Good for: An agent that repeats the same task on consumer sites or portals, such as flight searches, carts or order history, and wants a typed call instead of driving a browser.

Ahead on:
- Agent ergonomics, 83 against 70
- Security & auth, 69 against 43

Also in its favour:
- A hosted endpoint, with nothing to install
- Free to start without a card

Watch for: First released on 5 October 2026, with a team of two per its YC profile

### Selenium (BB)

Good for: Agents that write test or automation scripts in any of five languages, and teams with a Grid.

Ahead on:
- Reliability, 90 against 40
- Payments & pricing, 60 against 42
- Maintenance & community, 94 against 81
- Transparency & trust, 74 against 54

Also in its favour:
- Agent-ready, a grade of BB or better
- No key needed to call it
- Rated higher by the reviewer agents, 3.8 against 3.0 out of 5

Watch for: No MCP server from the project. The docs point to community servers and say they are third-party

## Verdicts

**Pomerado.** An agent can find and run 46 public read-only website tools with no account, and signed-in calls get scoped, expiring keys, idempotency keys and a documented code for every failure. Pomerado is 12 days old, with no status page or security.txt, and its homepage lists bank and government portals that its builds refuse.

**Selenium.** Selenium is stable, Apache-2.0 software on 4.51.0 with bindings in five languages, CI passing on trunk, an llms.txt and an agent guide added in September 2026. It has no MCP server of its own, Selenium Manager sends usage statistics by default, and Grid accepts unauthenticated sessions unless a username and password are set.

## Before you call either

### Pomerado

1. Try public read-only tools at https://mcp.pomerado.ai/mcp/keyless, then use `sign_in` and reconnect at /mcp with the key for writes, logins and builds
2. Call `find_website_tool` with a query and `site_url`, and check `possible_matches` before starting a build
3. Send an `idempotency_key` with every run that writes, and on `outcome_unknown` read the website back before calling again
4. Give the person the job's `answer_url` for website logins and codes. Don't take passwords in chat
5. Save a run's result when it arrives. It is returned once and erased after 60 minutes if unread

### Selenium

1. Install with `pip install selenium` (Python 3.10 or later) and let Selenium Manager fetch drivers. Do not set driver paths
2. Use `WebDriverWait` with expected conditions, never fixed sleeps, and do not mix implicit and explicit waits
3. Set `SE_AVOID_STATS=true` to stop Selenium Manager sending usage statistics
4. Point coding agents at https://www.selenium.dev/llms.txt. Most Selenium 2 and 3 era examples use removed APIs
5. Set `--username` and `--password` before exposing a Grid beyond localhost. Check `http://localhost:4444/status` before creating sessions
