If you're a 200-person company with an SRE team and a Datadog budget, use Datadog. If you're a 10-person team shipping on Vercel and you want reliability practice without a dedicated SRE, use Greenslope.
This page is a positioning narrative, not a feature matrix. It should help you self-select — the right customers pick Greenslope, the right customers pick Datadog, both leave respecting the other.
Datadog, on its own terms.
Datadog is the industry-standard enterprise observability platform. APM, logs, metrics, RUM, synthetics, security, dashboards, SLOs — the whole breadth, deeply featured. Huge integration catalogue, mature query languages, and extensive customisation.
Its centre of gravity is an SRE team driving reliability practice across a large system with many services and custom signals. It is excellent at that — and priced accordingly.
When we'd tell you to pick Datadog.
We'd rather you pick the right tool and trust us than adopt Greenslope for a job it isn't the right shape for.
- You have a dedicated SRE or platform team with time to configure dashboards, write query-based alerts, and maintain tagging discipline.
- You need custom metrics, StatsD, Prometheus scraping, or deep log-search across heterogeneous infrastructure.
- You run on AWS / GCP / bare metal with heavy custom instrumentation, not a PaaS.
- You need a single vendor covering APM, logs, RUM, synthetics, and security monitoring with contractual coverage.
- Procurement already has a Datadog MSA and you want to consolidate within it.
When Greenslope is the better shape of tool.
Greenslope is Auto-SRE for small, shipping-fast engineering teams. If this is you, keep reading.
- You ship on Vercel (or similar PaaS) and your primary reliability question is "did my last release break something?".
- You're a small team — roughly 1 to 20 engineers — without a dedicated SRE.
- You want opinionated defaults: SLOs proposed for you, thresholds tuned from what the product observes, rollback suggestions on-alert.
- You want to pay for one product that closes the incident loop, not for a platform you have to configure into one.
- You want EU data residency by default and a UK / EU vendor posture.
- The Datadog per-host, per-metric, per-log-line pricing surface is friction you'd rather not navigate at this stage.
Non-goals — on purpose.
Every product is a set of choices. Here's what we've deliberately decided not to compete on.
Custom metrics / StatsD / Prometheus
Traces are Greenslope's input. We don't ingest custom application metrics; Datadog does, and does it well.
Log aggregation
Datadog Logs is a mature product. Greenslope reads platform logs only to extract release metadata. If log search is your primary need, use Datadog.
RUM and synthetics
Frontend real-user monitoring, session replay, synthetic probes — explicit Greenslope non-goals. Datadog is the right tool.
Security monitoring / CSPM
Datadog has a security portfolio. Greenslope isn't a SIEM. If you need those, pick the tool that's built for them.
Dashboard flexibility
Datadog's dashboard builder is extraordinary. Greenslope's views are opinionated and limited by design — we present conclusions, not query surfaces.
Integration breadth
Datadog has 700+ integrations. Greenslope's surface is narrower and deliberately so; if you need a long-tail integration today, odds are we don't have it.
They aren't always either/or.
Teams occasionally run both during a transition. More common: teams rule Datadog in or out up front, because the commercial and operational shape is different. If you tried Datadog, found the configuration burden too high for your stage, and went looking for something that felt more like a product and less like a toolkit — Greenslope is built for that moment.
If you’re on Datadog today and happy: we’d rather you stay on Datadog than switch and struggle. Greenslope is not a cost-switching play.
