etcd
A reliable distributed database for managing critical configuration and state across clustered systems
- Also known as
- etcd
What is etcd?
A distributed key-value store designed to reliably store and manage critical shared state across multiple machines. It provides strong consistency guarantees via consensus, automatic TLS encryption, and gRPC APIs.

etcd FAQ
Common questions about etcd, answered from independent, dated evidence.
What is etcd?
etcd is a strongly consistent, distributed key-value store that provides a reliable way to store data that needs to be accessed by a distributed system or cluster of machines. It gracefully handles leader elections during network partitions and can tolerate machine failure. It is indexed under Key-Value Stores.
Source: https://etcd.io
Is etcd free to use?
etcd is open source, so it can be self-hosted and used at no licence cost. It is released under the Apache-2.0 licence. Pricing changes often, so verify at source before relying on it.

What platforms does etcd support?
etcd supports a command-line interface. Platforms we have not confirmed are simply not listed here rather than ruled out.
Source: https://etcd.io
Can etcd be self-hosted?
Yes. etcd can be deployed self-hosted, so it does not have to run on the vendor's infrastructure.
Source: https://etcd.io
What does etcd integrate with?
We have confirmed 29 integrations for etcd, including Kubernetes, Vitess, fleet, Docker, Puppet, confd, AWS ECS and SkyDNS, plus 21 more. This is what we could verify from public sources, so the vendor may support others we have not indexed.
Source: https://etcd.io
Is etcd open source?
Yes. etcd is published under the Apache-2.0 licence, a permissive licence that generally allows commercial use and modification. Licence terms can change between releases, so verify against the repository for the version you intend to use.

The vioscaleAI score: one lens on the evidence
Not user reviews and not a paid placement: a confidence-weighted blend of the independent signals below (adoption, activity, security posture, and more), which you can sort and re-weight yourself. Vendors can correct their listing but can never move their rank, and stars are weighted low as a vanity metric. It is one way to read the evidence for etcd, not the verdict.
