CRN’s list of 10 coolest open-source tools in 2021 so far include python-based restore tooling from Aiven and cloud-use cost visibility from Stackwatch.

Altair GraphQL Client
Netherlands-based software developer Samuel Imolorhe is behind this open source debugging tool for GraphQL APIs.
Version 4, released in March, migrates the tool from Angular V9 to Angular V11, speeding the application and improving performance. Altair also introduced a way to perform logic on query results and gave users ways to configure proxy settings on desktop apps and hide extensions data returned from some servers.
Some hype around GraphQL and graph databases has built in recent years, with Dgraph Labs raising more than $14 million in funding since its founding and next-generation graph database developer Neo4j raising $325 million in a Series F round earlier this month. Neo4j offers a GraphQL library for low-code API development.
