Your team still loses hours every day inside a browser.
Browstack is a browser-automation agency. We sit with your ops team, map the workflows they repeat, and ship reliable automations with full audit trails — so your people stop doing what software should be doing.
Built on the same infrastructure as modern AI agents
The gap LLMs left open
LLMs didn't solve the browser. Not yet.
Claude's and OpenAI's browser agents are impressive demos. In production they're still brittle, slow, and expensive on tokens. WebArena and similar benchmarks put state-of-the-art success rates below what any ops team would tolerate.
And most of the tools your team actually uses — old admin panels, customer portals, supplier extranets — have no API, no MCP, no webhook. Browser automation is the only way in.
Generic agents are brittle
A small DOM change breaks the run. Retries burn tokens and time without solving the underlying issue.
No API, no MCP
The systems your ops team logs into every day were never built for programmatic access.
Compliance & audit
You need to know exactly what ran, when, on which account, with what result. Most setups can't show you.
Token economics
Letting a generalist LLM drive every click for hours doesn't pencil out. Hybrid automation does.
Anatomy of a workflow
The right tool for each step, not one tool for everything.
We compose deterministic Playwright, vision models, and LLM judgment calls into a single observable pipeline. Each step is versioned, logged, and replayable.
What we automate
If a human does it in a browser on a schedule, it shouldn't be a human doing it.
Behind every ops team is a hidden factory of repetitive browser work — vendor portals, legacy dashboards, login-gated tools. We turn that work into programmable, observable infrastructure.
Persistent sessions
We stay logged in across runs — through SSO, MFA and saved auth context — so portals never see a cold start.
Human-like navigation
We don't depend on brittle CSS selectors. The automation adapts when a portal quietly changes its UI.
Bulk, reliable forms
Hundreds of records, filled and submitted in parallel, with validation before anything is written.
Files in and out
PDFs, CSVs and statements captured, parsed, uploaded and verified — not just clicked past.
Audit & replay
Every run captured end-to-end: video, DOM snapshots, decisions. Replayable for compliance.
No vendor cooperation
If a human can do it in the browser, we can automate it — no API, no MCP, no waiting on IT.
Use cases
Where teams put us to work.
Insurance form hell, gone.
Sidecare is a health-insurance broker. Every time it signs a new company, ops has to register that company and every single employee on the insurer's platform — by hand, copy-pasting from Sidecare's back office into a portal that has no API. At scale this was dozens of hours every week of pure transcription, with the data-entry errors that always come with it.
We mapped the back-office → insurer flow end to end, then built an automation that reads each newly signed contract from Sidecare's back office and registers the company and all of its employees on the insurer platform. Every field is validated before submission, every run is captured, and an ops lead gets a report of exactly what was created.
“The part of the job everyone dreaded just disappeared. New deals get set up the same day now.”
Outcome
Onboarding that used to take an ops person a full afternoon now runs unattended in minutes. The team stopped copy-pasting and went back to actual broker work.

Healthcare
Payer portals, claims, eligibility and credentialing — handled without an army of clerks.
Insurance
Carrier portals, policy verification and renewals across systems that don't share data.
Fintech
Banking portals behind MFA, statement pulls and reconciliation in isolated browsers.
Data entry
The copy-paste between two systems that never got an integration. We are the integration.
KYC / KYB
Pull registry filings, screen sanctions and UBOs, and assemble a review-ready packet.
Methodology
A four-step engagement. Predictable, auditable, boring on purpose.
Sit with your ops team
We spend a week shadowing the people doing the work. We find the repetitive, high-volume, low-judgment tasks that drain hours every week.
Map the workflow
Every click, every conditional, every edge case — documented. You get a clear picture of what we will automate before a line of code is written.
Ship the automation
Built on Browserbase and BrowserOS, with hybrid LLM steps where it actually helps. Versioned, monitored, runnable on demand or on a schedule.
Audit & report
Daily, weekly, and monthly reports. Every run captured — video, DOM snapshots, decisions. You see what shipped and what failed.
The stack
Best tool in the market, no reinventing the browser.
We ship on Browserbase for headless cloud browsers and BrowserOS for desktop-grade agent control. Where an LLM call genuinely helps — reading a PDF, judging a free-text field — we use it. Where deterministic code is faster and cheaper, we use that.

}Daily reporting
You always know what shipped, what failed, and what it saved.
Every run captured end-to-end. A summary lands in your inbox every morning. A digest every Monday. A board-ready review every month — with the hours we gave back.
- Per-run video and DOM snapshots
- Step-by-step decision log
- Slack alert on first failure
- CSV / API export of every run
