GreenSlope

Reliability for teams that ship fast

Catch regressions in minutes, not post-mortems.

GreenSlope watches every deploy, correlates errors with the commit that caused them, and writes the first draft of your incident response, so engineers keep shipping and on-call stays quiet.

Latency regressed at 14:19 UTC, 2 min after deploy a7f3c9d to payment-service. Introduces an uncached call to stripe.PaymentIntents.retrieve inside the cart-total loop. Suggested fix: revert or add Redis cache.

Where users are hitting issues, right now.

Each pulse is a real user running into an error somewhere in the world. The map is illustrative; we'll wire it up to live telemetry once the design lands.

§ 01What GreenSlope does
Read: 2 min

Three jobs done well, not thirty done badly.

Deploy-aware error tracking

Every exception is tagged with the commit, author, and feature flag that introduced it. The diff that broke production is one click away; no archaeology across Git blame and log files.

TracksCommitsFlagsRegressions

AI root-cause agent

When latency or error rates spike, the agent traces through your recent deploys, correlates with metric anomalies, and opens an incident with a proposed fix. Accepts it, reverts it, or routes it to the right team.

SurfacesCauseSuggested fixRunbook

Incident loop in Slack

Runs the scribe, timeline, responder coordination, and postmortem draft entirely in Slack. Your engineers stay in the tools they already use instead of switching to a standalone incident console during the worst moments.

§ 02Deploy-aware tracking
Feature

Every error, tied to the commit that caused it.

How it works

Find the diff, not the needle.

We ingest your deploy events from GitHub Actions, Vercel, Argo, or a simple webhook, then fingerprint every exception, trace, and log line back to the commit SHA that produced it. The moment an error regresses, the suspect diff is pinned to the alert.

Deploy timeline · payment-service

last 24h

p95 latency for payment-service over 24 hours, with deploy markers and a regression. Latency holds between 175ms and 200ms through the morning, then climbs sharply after the 14:00 deploy (a7f3c9d), breaching the 800ms SLO around 14:45 and peaking near 1320ms by 15:30.
p95 latency by time, in milliseconds. Deploys occurred at 09:30, 11:00, 12:30 and 14:00. The 14:00 deploy (a7f3c9d) is the regression culprit; the 800ms SLO is breached at 14:45.

Root-cause agent

Writes the first draft so your engineer can approve, not investigate.

The agent walks your traces, metrics, and deploy timeline the way a senior engineer would. It produces a plain-English explanation, a ranked list of suspects, and a suggested fix, usually in under 45 seconds, well before the second alert fires.

Incident loop in chat

The console is a channel. The postmortem writes itself.

When a SEV opens, GreenSlope spins up a channel, assigns Incident Commander and Scribe, and summarises every action into a running timeline. After resolve, it drafts a postmortem in your format: causes, timeline, impact, next actions. Ready for edit, not for writing from scratch.

"We cut mean-time-to-detect from 18 minutes to under four, and our on-call rotation stopped being the reason people leave the team."
