Twin Browser vs the field, in spec tables.
Every page is a side-by-side spec table plus a plain “when to pick which” verdict — including the jobs where the other tool genuinely wins. Twin’s own edge: you hand an agent the whole web and keep the guardrails.

Why teams pick Twin
Delegate the whole web — keep the guardrails.
The category is crowded with capable browsers. Twin’s difference is that you hand off the busywork and still set the limits — and, as agents repeat work, three mechanisms make the next run cheaper instead of dearer.
Cost trends toward zero
Most browser infrastructure re-runs the LLM on every execution, so spend climbs with usage. Twin compiles a task once; repeats hit the cache and replay at ~$0 model cost.
Deterministic replay
A compiled skill blind-replays with no model in the loop — production-ready, not a debug recorder. The most-repeated workflows stop paying per run.
Cross-tenant skill corpus
Sanitized skill skeletons are pooled across the network, so your cache-hit rate climbs as everyone automates the same hosts.

The mechanics behind the numbers
The capabilities each spec table measures — and where teams put them to work.
Hand over the work. Keep the guardrails.
Compile a task once, match a re-phrased request with a semantic dispatch cache, and replay it deterministically with no LLM in the loop. The full argument is on why Twin.
