The Skyvern alternative where cost falls with usage.
Skyvern is the closest competitor on caching, and that’s exactly why the gap matters: its cache is param-hash keyed and single-tenant. Twin matches semantically across workflows and pools skills across tenants, and stays in the self-serve mid-market lane Skyvern is leaving for enterprise.

The cheapest LLM call is the one you don’t make.
Where Skyvern leaves cost on the table:
Semantic dispatch cache
A new, differently-worded request is vector-matched to a skill you already compiled and adapted to the new values — a hit is roughly 5× cheaper than recompiling, where Skyvern's replay (if any) is exact-match only.
Cross-tenant skill corpus
Sanitized skill skeletons are shared across the network, so your cache-hit rate climbs as everyone automates the same hosts. No competitor pools skills across tenants.
Deterministic replay at ~$0 LLM
Once compiled, a skill blind-replays with no model in the loop — so the most-repeated workflows trend toward zero marginal LLM cost instead of paying per run.
Twin Browser vs. Skyvern, answered
Skyvern has caching too — how is Twin’s different?
Skyvern’s @skyvern.cached is keyed on a parameter hash, so it only helps when the same workflow repeats with known parameters. Twin’s cache is a vector match: it finds a semantically similar skill even for a new, re-worded task, and the cross-tenant corpus means you benefit from skills the whole network compiled.
Run the same workflow for a fraction of the cost.
Compile once, dispatch semantically, replay deterministically. Start free — no LLM bill on a cache hit.
