Vibe coding is unpredictable. Code reviews are for humans!
PROBLEM
Reviews are inconsistent
Pull request signals are scattered
Your codebase lives in GitHub, discussions in Slack, and issues in Linear.
SOLUTION
Unified data
Builds a lineage for each PR with tooling metadata and behavioral patterns, so you can query it using deterministic SQL
SOLUTION
Unified data
All events, one schema
Warestack unifies all signals into a structured dataset. Access it in our dashboard, as raw data through our API.
Query it with deterministic SQL or feed to LLMs.

FEATURE 1
Create checks
Enrich with behavioral pattern metadata
Teams work in patterns!
Warestack lets you create your own pattern checks to detect team actions. It then attaches the results directly to your PR as meta-data.
It is useful for causality and regression, connecting present and historical patterns into a structured dataset.

See every PR signal in one place — and act on it

Warestack ingests diffs, CI artifacts, review comments, linked issues, Slack threads and deployment events and maps them into a unified, queryable schema. That single source of truth makes it possible to write simple, explainable policies that reason over the whole lifecycle, not just a single event.

Contextual Review

"If a PR modifies payment code and tests are flaky, require an extra reviewer."

Safe Deployments

"If a PR links to a Linear task marked 'hotfix' but deploy time is outside business hours, block deploy."

Incident Correlation

"Show correlation: PR → failing workflow → incident ticket."

4,703 repos in sync
We process thousands of GitHub operational events for our customers, capturing hundreds of contextual signals for every PR.

Why Warestack?

Monitor DevOps processes, not just errors—with context-aware governance.

FeatureWarestackAI code review toolsGitHub (native features)
Process monitoring (How, Why, When)Tracks DevOps processes—how changes were made, why decisions were made, and under what conditions. Links PR → review → deployment → incident chains.Focus on individual PRs; no cross-event correlation or workflow context.Tracks what changed (code, metadata); no process context or post-merge chain linking.
ExplainabilityDeterministic checks + evidence recorded on PRs/issues.Opaque AI responses; difficult to trace why suggestions were made.No built-in explainable policy engine.
Human-language queriesSearch and ask in plain English across PR history.Limited query capabilities; typically focused on current PR only.No query layer.
Context-aware rule enforcementAdaptive rules that consider developer role, timing, and team context. Enforce based on real-world conditions, not just binary checks.Provide suggestions and comments; cannot enforce or block merges.Binary branch protection (yes/no); cannot adapt to context like developer seniority or deployment timing. Protection rules end at merge button.
Operational agents (Slack/Linear)Post actionable comments into Linear and Slack with context.Basic notifications; limited integration with workflow tools.Notification-only.
Centralized audit trailCentralized evidence trails with full context—who violated what rule, when, why, and what it impacted. SOC-2 ready workflows.Limited audit trails; difficult to prove why decisions were made.No centralized audit bundle across tools; violations scattered across repos.
Build the way the PROs do.
