Cheaper, safer, remembered - without changing how you work
Surfil sits beside the agent you already use, byte-exact, so you get lower spend, a secret firewall and memory that carries over - with nothing new to learn.
What you turn on
You just want your agent to cost less, leak nothing, and stop forgetting your codebase - not another tool to babysit through a config file.
Install and forget
One command, byte-exact passthrough; your agent behaves exactly the same, just cheaper and safer.
Get the receipt
After a normal week, a signed savings receipt shows what you recovered - proof, not a vibe.
Keep your memory
Facts you establish follow you across agents, so your mornings stop starting from zero every time.
Why it stays out of your way
Zero config lock-in
Passthrough preserves your prefix cache and a clean uninstall restores every config byte-for-byte.
Starter covers the basics
Core, Guard monitoring and the Cap ledger come with Starter at $5/mo; you upgrade only when the savings justify it.
Your dashboard, your data
Metadata only, on your own account - it records agent actions, never your keystrokes or your source.

Same spine, a neighbouring starting point.
Engineering lead
Give every developer the same interception point, watch cost and risk in one pooled view, and roll out guardrails on evidence instead of on a mandate.

Zero-trace by construction, fail-closed enforcement and offline-verifiable evidence - the posture that turns an agent ban into a governed, reviewable rollout.
See this path →Platform / DevEx
Standardize agents the way you standardize everything else: one on-device layer, byte-exact, that every product plugs into - never a second proxy to run.

The install is reversible byte-for-byte, and the first signed receipt arrives after one normal week of traffic.
