Browser automation alternative
The browser automation alternative built for agents
Browser automation and computer-use agents click through UIs that break the moment a button moves. Zatanna works at the request layer — reverse-engineering the network calls behind any portal and exposing them as one stable API your agents call directly.
Skip the browser. Call the request underneath.
Browser automation fights the interface
Launching Chrome, rendering HTML, running JavaScript, waiting on selectors — every step is overhead, and every one of them breaks when the UI shifts.
Zatanna talks to the system directly
We observe the workflow once, reconstruct the underlying HTTP requests — auth, sessions, sequencing — and host them as one clean endpoint. No browser involved.
Built to survive production
Stateful auth and MFA, request replay, automatic retries and re-auth, anti-bot and TLS hardening, plus portal-change detection that repairs itself.
Browser automation vs. Zatanna
| Criterion | Browser automation / computer use | Zatanna |
|---|---|---|
| Execution speed | 8–15s per workflow — full page render, JS, waits | 200–500ms per workflow — direct request calls |
| Reliability | Breaks when a selector, layout, or button moves | Stable at the request layer, independent of the UI |
| Infrastructure cost | 200–500MB per headless Chrome instance | Under 10MB per workflow — no browser |
| Maintenance | Constant selector and timing fixes | Self-healing — change detection and auto-repair |
| Anti-bot detection | Triggers behavioral and fingerprint detection | TLS-hardened, session-aware request sequencing |
| Auth & MFA | Manual, fragile cookie and session handling | Managed auth, MFA, and session refresh underneath |
| Output | Scraped HTML you have to parse | Clean, structured API responses |
| Agent ergonomics | Screenshots, DOM clicks, brittle scripts | One stable endpoint your agent calls directly |
Bring one blocked workflow. We'll turn it into a production API.
Common questions
For most production workflows, yes. Anywhere you're driving a headless browser to log in, submit forms, or pull structured data, Zatanna reconstructs the underlying requests and hands you a single endpoint instead. The rare exceptions are workflows that depend on heavy client-side computation or truly one-off interactions.
Computer-use agents are great for exploration and novel tasks. But when a workflow matters in production, sending screenshots to a model and clicking pixels is slow, expensive, and nondeterministic. Zatanna runs the same workflow at the request layer — milliseconds instead of seconds, and the same result every time.
Because we work below the UI, frontend redesigns rarely touch your integration at all. When backend behavior does change, our observability layer detects the break and we repair the integration automatically — so you treat workflows like stable infrastructure.
Yes. We manage stateful auth, MFA, cookie and session refresh, request sequencing, proxy networks, and TLS fingerprint hardening underneath the endpoint. Your agent just calls the API.
