Measure and improve your agentic SDLC

Tuneloop analyzes every coding-agent session and links it to outcomes — so you can benchmark models on your own sessions and route each task to the cheapest one that holds up.

for platform teams reimagining the SDLC with AI

01The questions

Can you answer these?

  • Which work actually needs a frontier model, and what can move to cheaper models without losing quality?
  • Did switching models change what ships?
  • What did it actually cost to ship a feature?
  • Are there teams or repos where AI struggles?
02Benchmarks

Benchmark agents and models on your own data

New models and agents land every other week, and you don’t have the cycles to keep up.Tuneloop turns real tasks from your own sessions into benchmarks, replays them on any model, and grades each against what actually shipped — a leaderboard that reflects your environment, not someone else’s.

A benchmark built from your own sessions — every model × harness scored on the same frozen tasks.

03Routing

Bend the spend with smart routing

Think routine codebase exploration can move to a cheaper model? Replay it, check the gap, and route it with tuneloop-auto, in the Tuneloop router or as a policy in your gateway. You get routing rules justified by offline benchmarks, and continuous monitoring of live outcomes.

04Outcomes

Watch outcomes on live traffic

Every task, routed or not, is tracked against what it produced: cost, speed, rework, and defects. If outcomes slip on routed traffic, you’ll see it.

05Attribution

Trace the spend to what ships

Tokens and PR counts measure activity. Tuneloop links every session to the PRs, tickets, and features it produced, so spend lands on outcomes, by feature, team, and repo.

06How it works

Capture · Link · Replay · Route

Capture

Transcripts from every agent session — Claude Code, Cursor, Codex, OpenCode, Pi, your own harness. They never leave your infra.

Link

Every session tied to the outcomes it produced, and split into tasks tagged by type, domain, and complexity.

Replay

Tasks from your sessions and merged PRs re-run on candidate models — score vs. cost per task.

Route

Configs that clear your quality bar become routing rules — in our router or your gateway.

savings verified against outcomes

We’re building Tuneloop now, with a few engineering teams. If you’re wrestling with the questions above, start with a model-mix audit of your own sessions.

Where your spend goes, by task type, and what could move.
