Scale-First
Extraction
Engineered
High-volume web scraping is an industrial workload. What matters is not whether a single session can load a page. What matters is whether you can sustain throughput at high concurrency, stable access under drift, and predictable cost per successful session.
What Breaks at Scale
And Why It's Predictable
Drift Becomes an Outage Multiplier
At high volume, small detection shifts cascade: success rate drops → retries spike → proxy spend explodes → latency climbs → backlog grows → SLAs break.
The failure is usually partial degradation, not total block
Automation Artifacts Amplified by Repetition
High-volume pipelines are measurable. Browser or control plane leaks become statistically obvious, blocking becomes correlated across sessions.
Fixes require constant patching and target-specific hacks
Launch Overhead Dominates Unit Economics
In bulk collection, the most expensive thing is often not the scrape, it's spinning up the browser and paying for time to first render.
Slow launch bounds throughput and raises infrastructure spend
Proxy Spend Without Routing Policy
Naively proxying everything through premium egress produces unnecessary bandwidth cost, slower pipelines, and higher variance.
Routing policy keeps cost stable as targets harden
Optimized for
Concurrency
And Automation
Unlike "anti-detect browsers" designed for human operators, Undetect is engineered for automation-first execution with aggressive performance and resource optimization.
Automation is First-Class
Programmatic control, repeatability, pipeline integration, not human-driven UI workflows.
Resource Efficiency as Product Requirement
Reduced memory overhead, CPU churn, and variance between sessions under load.
Sub-500ms Browser Launch
Shaving seconds off session startup is a fundamental unit-economics improvement.
Built for Bulk
Web Scraping
Predictable Concurrency
Sustained high concurrency without stability experiments. Coherent behavior under load where many "stealth" products degrade.
Unlimited Fingerprints
No metering. Large, continuously refreshed database removes the bottleneck of synthesizing low-quality profiles or reusing small pools.
Chromium-Level Evasion
Stealthium solves evasion inside Chromium and V8, avoiding brittle patch stacks that fall apart under repeated, measurable automation.
Optional Proxies + Routing
BYO or use our panel. Per-URL routing reserves premium egress for high-risk endpoints, reducing bandwidth waste.
Integrated Captcha Handling
Captchas treated as normal operating conditions. Integrated handling so scraping code doesn't devolve into retry logic.
Operational Clarity
Explainable failures: target change, route quality, challenge frequency, not superstition. Metrics that are controllable and improvable.
What "Good"
Looks Like
A high-quality bulk scraping system should show controllable, improvable metrics, not mystery.
Stable Success Rate Under Drift
No silent coverage collapse when targets change.
Bounded Retries
No cost blowout during partial degradation.
Predictable Cost Per Session
Unit economics you can forecast and optimize.
Tight Launch-to-Action Latency
Startup isn't the throughput bottleneck.
Validate Sustained
Throughput Under Drift
A credible POC is not a single run. We validate over a representative window: sustained throughput at target concurrency, launch latency distribution, success rate across target sets, and operational recovery when targets change.
