now in early access

the context layer for engineering.

klarhed grounds every review, every agent, and every new line of code in the context your team already has. fewer regressions. faster merges. reliable products by default.

regression risk. incident INC-241 (Mar 4) was caused by a 60s idempotency TTL colliding with retry storms. consider 24h, matching the fix that shipped in #391.

product context. support flagged 12 duplicate-charge tickets last quarter tied to this path. the expiry check aligns with LIN-1204.

approved with note. ready to merge. linked incident and support thread attached.

what ships today

reliable code, without the tribal knowledge tax.

code represents the status quo of your product, but it doesn't know what's been debated, fixed, or deliberately left alone. klarhed does.

automated code review

every PR reviewed against your codebase history, incident log, and product decisions. not style nits, real risk.

$ klarhed review --pr 482

end-to-end QA that remembers

flows generated from actual usage, replayed on every merge. regressions caught before they hit main.

$ klarhed qa --run smoke

context-aware generation

serve your agent the constraints it needs: past incidents, deliberate choices, product intent, over MCP or API.

$ klarhed mcp serve
how it works

three steps. no new place to check.

01

point it at your repos

install the github app or run the CLI. klarhed indexes your code, PR history, and CI signals, including across split repos (no monorepo required).

02

connect what you already run

grafana, sentry, pagerduty for reliability. linear, jira, github issues for intent. klarhed reads them; you don't manage a second knowledge base.

03

it shows up where you work

in PR reviews, in CI, in your editor over MCP, or as a plain API. your agents call it. your engineers barely notice it, until it saves them.

the context graph

one graph. every signal your product runs on.

klarhed keeps the raw data so you can inspect it, and derives a structured graph agents can actually reason over. models will commoditize. your context won't.

  • grounded in code as the source of truth
  • enriched by every tool your team lives in
  • queryable over API, MCP, github actions, or CLI

reliability and engineering context, first.

klarhed starts where reliability is decided: CI, observability, and on-call. new sources land as early-access teams ask for them.

principles

the commitments we won't quietly walk back.

open source

the core is open. audit it, self-host it, extend it. no black boxes in your critical path.

access however you want

API, MCP, github actions, CLI. klarhed adapts to your stack, not the other way around.

european by default

built in europe, hosted in europe. GDPR-native. data residency is a switch, not a sales call.

ship reliable code.
klarhed remembers the rest.

we're onboarding a small group of early-access teams: engineering teams with real codebases, real incidents, and the appetite to shape the product with us.
