Latitude is an observability platform specifically tuned for Claude Code usage. It captures every turn an agent runs — the prompts, tool calls, bash output, files touched, system prompt, and the tool schemas Claude Code composes at runtime — then surfaces it as cost breakdowns per prompt, per session, and per workspace. The platform routes Claude Code traffic through Latitude's instrumentation layer, giving engineering teams real visibility into what their AI coding agent is actually doing versus what they expect it to do. Teams can trace expensive tool-call chains, spot runaway loops, identify which slash-commands are budget-efficient, and attribute costs to specific tasks or repos without wading through raw OpenTelemetry traces. In a world where Claude Code rate limits and API costs are a real engineering budget concern, Latitude fills a genuine observability gap. It launched on Product Hunt today with 150 votes and complements Claude Code's native OpenTelemetry support by adding a human-readable interface and cost attribution dashboard that raw traces simply don't give you.

Litmus
Unit tests for AI — find the cheapest model that passes your prompts

Litmus is an open-source testing framework for AI prompts — the missing unit test layer between "it worked once" and "it works reliably across models." You define test cases (prompt + expected behavior assertions), run them against multiple models simultaneously, and Litmus reports which models pass and — crucially — projects the cost difference at scale. The goal: find the cheapest model that meets your quality bar. The workflow is intentionally simple: litmus init to scaffold a test suite, write YAML test cases describing prompt inputs and assertions, then litmus run to execute against your chosen model roster. Results show pass/fail per model, inference latency, and a cost-at-scale projection (e.g., "using claude-haiku instead of opus would cost 94% less at 1M requests/day with 97.3% pass rate"). This directly addresses one of the most expensive habits in AI development: defaulting to the most capable (and most costly) model for every task. Litmus launched fresh with 74 GitHub stars in its first hours, suggesting real demand. It integrates with the Anthropic, OpenAI, and Google APIs and supports custom model endpoints for local testing.
Reviewer scorecard
“Been waiting for exactly this. The per-session token breakdown finally shows which commands are bankrupting my API budget and which are model-efficient. The system prompt inspector — showing what Claude Code actually sends as context — is worth the signup alone.”
“Every production AI team needs this and most are doing it manually with spreadsheets. The cost projection feature alone is worth shipping — I've watched teams spend 10x more than necessary on inference because they never systematically tested cheaper models. This is the tooling that makes responsible model selection practical.”
“You can get 80% of this from Claude Code's built-in OpenTelemetry output piped into a free Grafana dashboard. Latitude is betting that most teams won't DIY it — that's a fair bet — but the freemium paywall likely arrives before you're convinced to hand over a credit card.”
“The fundamental challenge with prompt testing is that assertions are hard to write well — defining 'correct' AI behavior is often subjective and context-dependent. New project with 74 stars means no battle-testing, no community-contributed assertion patterns, and no guarantee the test framework won't produce false confidence. Wait for v1.0 with real-world case studies.”
“As AI coding agents become the primary way software gets built, observability for agent behaviour becomes as mission-critical as APM was for microservices. Latitude is staking out the right territory at the right moment — this category will be worth billions.”
“Litmus represents the maturation of AI development as a discipline — the shift from 'does it work?' to 'does it work reliably, cheaply, and measurably?' This is how software engineering grew up in the 2000s, and AI is following the same path. Tools like this will be table stakes in 18 months.”
“Knowing the exact cost of each creative brief I throw at Claude Code would change how I scope projects. Understanding where the token budget disappears makes it easier to write better prompts and structure tasks more efficiently.”
“Brand voice consistency is one of the hardest problems in AI-assisted content creation. Litmus-style testing against creative prompts — does this output match our tone guidelines? — is something agencies and marketing teams desperately need. The model cost comparison feature makes budget conversations with clients much cleaner.”
