Each dev keeps their workflow
Claude here, Codex there — people use what they like while cerver quietly keeps them on whatever wins per task.
01 — The hidden tax
Everyone got used to one tool. Nobody re-checked whether it's still the best.
Standardizing on a single agent felt like governance. In practice it's a silent, compounding cost: the work goes to a model that may have been overtaken months ago, and no one has the numbers to notice.
02 — Flexibility, per person and per task
The right mix across your team — without a migration project.
Route by policy
Set defaults and guardrails per app, per env, per team — one session boundary, any provider behind it.
Switch with zero lock-in
Models change monthly. Moving the whole org to a new one is a config change, not a rewrite.
03 — The numbers to prove it
Route by what each job is worth — and show the diff.
cerver runs the same task on more than one agent and records the per-task outcome, cost, and latency. You make the call with evidence, not habit.

Run on the infrastructure you already trust.
Bring your own provider keys and compute — your Mac fleet, Vercel, E2B, Cloudflare. cerver doesn't store model secrets; they stay in your vault, with scoped runtime access and a record of which provider was used.
