Live tracking vs retrospective analysis. Self-serve vs sales calls. We compare the two approaches to measuring AI developer productivity.
If you're evaluating tools to measure your engineering team's AI productivity, you've probably found us and Exceeds AI. Both solve the same problem: proving AI ROI to leadership. But the approaches are fundamentally different.
Here's an honest comparison.
CostLens captures AI usage as it happens — via an SDK in your code, an MCP server in your AI coding tools, or a local proxy. We know which tool generated which code because we're in the loop.
Exceeds AI analyzes commits after the fact — scanning diffs and patterns to guess which code was AI-generated. They look at the output and infer the input.
| CostLens | Exceeds AI | |
|---|---|---|
| Detection method | Live capture (SDK, MCP, proxy) | Retrospective commit analysis |
| Setup time | 30 seconds (connect GitHub) | "Free pilot" (requires a call) |
| Pricing | $49/mo Pro, $149/mo Business | Not published |
| Who installs | Individual engineer | VP/Director decision |
| AI tool coverage | Any tool with MCP (Cursor, Claude Code, Kiro) + SDK | Cursor, Claude Code, Copilot |
| Accuracy | Knows the exact tool and session | Infers from patterns (confidence score) |
| Free tier | Yes — 1 repo, basic dashboard | No — "free report" requires sales |
Commit-level heuristics work for obvious cases: a 500-line file created in one commit at 2am is probably AI. But they struggle with:
We see this in our own data. Our AI detection heuristic flags about 68% of PRs as AI-assisted. But when we check against MCP session data, the real number is closer to 90%. Retrospective analysis undercounts.
If you run CostLens's MCP server alongside Cursor or Claude Code, every AI interaction is logged with:
This means your dashboard shows not just "this PR was AI-assisted" but "this PR used Claude 4 Sonnet, consumed 45K tokens, cost $1.35, and shipped in 3.2 hours."
That's the difference between "AI helped" and "AI saved $X at Y speed."
CostLens: sign up → connect GitHub → see your dashboard. No call required. The free tier works with 1 repo.
For deeper tracking, install the MCP server:
brew install costlens
Or add the SDK to your Node app:
npm install costlens
Exceeds AI requires a "free pilot" which, based on their CTAs, involves scheduling a demo. If your team can't get budget approval without data, you're stuck in a chicken-and-egg loop.
Exceeds AI is a legitimate tool for large enterprises with dedicated vendor management. If you have 300+ engineers and a VP who wants a managed analytics vendor, they're a reasonable option.
But if you're an engineering manager or tech lead who wants to:
