What is Axiom?
Axiom is a modern logging and observability platform designed to let teams store, query and analyze enormous volumes of event data without the eye-watering bills that traditional log management tools are notorious for. Its core promise is simple but powerful: ingest all your logs and events — not just a sampled subset — and keep them affordably, so you actually have the data you need when something breaks at 2am.
The reason Axiom can offer this is its efficient, purpose-built architecture for time-series and event data, which dramatically lowers storage and query costs compared to legacy observability stacks. That cost efficiency changes behavior: instead of carefully deciding which logs to keep to control spend, teams can send everything and explore freely, which leads to faster debugging and better insight into how systems actually behave.
On top of storage, Axiom provides a fast query experience, dashboards, alerting and integrations with the tools developers already use, from common log shippers to serverless platforms and frameworks. It's particularly popular with teams running serverless and modern cloud architectures, where log volumes can explode and per-gigabyte pricing elsewhere becomes punishing. Features like structured event analysis, monitors that notify you when patterns change, and APIs for piping data in and out make it a genuine observability hub rather than just a log bucket. For engineering teams that want comprehensive visibility into their systems but have been burned by the cost of incumbents, Axiom offers a refreshingly affordable, developer-centric alternative that doesn't force you to choose between insight and budget.
What is MerchantDiff?
MerchantDiff helps Shopify developers stay ahead of platform changes without constantly monitoring changelogs and documentation. It tracks Shopify API updates, deprecations, documentation changes, deadlines, and important ecosystem announcements, then turns them into practical briefs explaining what changed, who is affected, what action is needed, and when.
What problem it solves
Shopify developers need to monitor multiple changelogs, documentation pages, API updates, and deprecation notices. MerchantDiff brings the important changes together and explains what developers need to do before updates or deadlines affect their apps and integrations.
