# ergo vs kratos

*GraphCanon updated Sep 20, 2026*

## Verdict

Pick ergo if ergo is an actor-based framework for Golang that simplifies the development of event-driven architectures with built-in network transparency inspired by Erlang and Elixir OTP; pick kratos if kratos is a Go microservices framework designed for cloud-native applications that supports both gRPC and HTTP protocols.

[ergo](https://ergo.services) reports 4.7k GitHub stars, 191 forks, and 0 open issues, last pushed Sep 7, 2026. [kratos](https://go-kratos.dev) has 26k stars, 4.2k forks, and 117 open issues, last pushed Sep 16, 2026. Figures are from public GitHub metadata via [ergo's repository](https://github.com/ergo-services/ergo) and [kratos's repository](https://github.com/go-kratos/kratos).

## Decision facts: ergo

- **Adopt for:** Ergo is an actor-based framework for Golang that simplifies the development of event-driven architectures with built-in network transparency inspired by Erlang and Elixir OTP.

## Decision facts: kratos

- **Adopt for:** Kratos is a Go microservices framework designed for cloud-native applications that supports both gRPC and HTTP protocols.

## Choose when

### Choose ergo if…

- Tags unique to ergo: actor-model, distributed-systems, event-driven-architecture, microservices.
- For projects requiring a robust actor-model system for handling event-driven microservices in Golang
- Leaner open-issue backlog (0).

### Choose kratos if…

- Tags unique to kratos: ai, architecture, cloud-native, framework.
- When you need to develop efficient and scalable microservice architectures specifically in the Go programming language, as Kratos offers dedicated support to optimize go-based services.
- More GitHub stars (26k vs 4.7k) - visibility, not fit.

## When NOT to use ergo

- If your project does not fit an event-driven or actor-based architecture model
- When the complexity of setting up a supervision tree and managing actors exceeds the needs of your application

## When NOT to use kratos

- If your project does not require Go or you prefer frameworks supporting a wider range of languages, as Kratos is specialized in the Go ecosystem and may introduce language-specific limitations.
- In scenarios where lightweight microservices without extensive framework overhead are preferred, given that Kratos includes features like gRPC out of the box which might add unnecessary complexity.

## Common questions

### What is the difference between ergo and kratos?

ergo: An actor-based framework for event-driven architecture in Golang. kratos: Go microservices framework for cloud-native applications. See the comparison table for live GitHub stats and shared categories.

### When should I choose ergo over kratos?

Choose ergo over kratos when Tags unique to ergo: actor-model, distributed-systems, event-driven-architecture, microservices; For projects requiring a robust actor-model system for handling event-driven microservices in Golang; Leaner open-issue backlog (0).

### When should I choose kratos over ergo?

Choose kratos over ergo when Tags unique to kratos: ai, architecture, cloud-native, framework; When you need to develop efficient and scalable microservice architectures specifically in the Go programming language, as Kratos offers dedicated support to optimize go-based services; More GitHub stars (26k vs 4.7k) - visibility, not fit.

### When should I avoid ergo?

If your project does not fit an event-driven or actor-based architecture model When the complexity of setting up a supervision tree and managing actors exceeds the needs of your application

### When should I avoid kratos?

If your project does not require Go or you prefer frameworks supporting a wider range of languages, as Kratos is specialized in the Go ecosystem and may introduce language-specific limitations. In scenarios where lightweight microservices without extensive framework overhead are preferred, given that Kratos includes features like gRPC out of the box which might add unnecessary complexity.

### Is ergo or kratos more popular on GitHub?

kratos has more GitHub stars (25,929 vs 4,658). Stars measure visibility, not whether either tool fits your constraints.

### Are ergo and kratos open source?

Yes - both are open-source projects on GitHub (ergo: MIT, kratos: MIT).

### Where can I find alternatives to ergo or kratos?

GraphCanon lists graph-backed alternatives at [ergo alternatives](/tools/ergo-services-ergo/alternatives) and [kratos alternatives](/tools/go-kratos-kratos/alternatives) ([ergo markdown twin](/tools/ergo-services-ergo/alternatives.md), [kratos markdown twin](/tools/go-kratos-kratos/alternatives.md)), ranked by typed relationship edges rather than popularity votes.

### Is there a machine-readable version of this comparison?

Yes. The markdown twin at [this comparison](/compare/ergo-services-ergo-vs-go-kratos-kratos.md) mirrors this page for agents and LLM crawlers, with the same stats table and FAQ answers.

### Which is better maintained, ergo or kratos?

ergo: Active. kratos: Very active. Compare maintenance labels, days since push, and release cadence in the trust section below - stars alone do not measure maintenance.

### Where are the full trust reports for ergo and kratos?

GraphCanon publishes per-repo trust reports with dated maintenance, provenance, and scan summaries: [ergo trust report](/tools/ergo-services-ergo/trust); [kratos trust report](/tools/go-kratos-kratos/trust).
