Early Access — Join the waitlist
Observability and governance
for your AI stack
StackLens gives your team one platform to manage prompts, trace every LLM call, and enforce governance policies — so you ship AI features with confidence.
No spam. Just your early access invite.
The problem
Prompt chaos
Prompts buried in code, no versioning, no safe rollout — one bad edit breaks production.
Blind LLM usage
No visibility into which models run, what they cost, or why requests fail.
Compliance risk
PII in outputs, no policy enforcement, no audit trail — auditors have questions you can't answer.
Three products, one platform
Everything your AI team needs
Prompt Management
FlowOps
Version, promote, and A/B test prompts across Dev → Staging → Production. No more editing prompts in code and hoping nothing breaks.
LLM Observability
StackTrace
Trace every LLM call with model, tokens, cost, and latency. Pinpoint failures and optimize spend — no more guesswork.
AI Governance
GovernAI
Define policies for PII detection, content safety, and cost limits. Catch violations, maintain an audit trail, and prove compliance.
