Fission vs incident.io: at a glance
What is Fission?
Fission's release feed carries only RC tags, and none of them say what shipped
Every entry here is a release candidate — v1.22.0-rc1 and rc2, v1.23.0-rc1, v1.25.0-rc1 — with no final release appearing between them, and the version sequence skips 1.24 entirely. The bodies are whatever the tagging commit said, so what reaches this feed is a dependabot bump, a CLI tool-version refresh, a codegen sync explicitly labelled as having no functional change, and one entry that is nothing but links to an external release-highlights page. The actual release notes live on the project's documentation site, not here.
What is incident.io?
incident.io's agent now runs your team's own tools, with a human approval before any change.
Investigations, the agent that posts a root-cause hypothesis when an incident opens, is the center of incident.io; it went GA and then doubled its speed in September. In October the company pushed its agent skills out into coding harnesses, then opened Nexus to customers' own tools and know-how. The 10-28 release restates that extension model and adds an explicit step: any change the agent proposes waits for a human approval before it runs.

◆ Current state
Every entry here is a release candidate — v1.22.0-rc1 and rc2, v1.23.0-rc1, v1.25.0-rc1 — with no final release appearing between them, and the version sequence skips 1.24 entirely. The bodies are whatever the tagging commit said, so what reaches this feed is a dependabot bump, a CLI tool-version refresh, a codegen sync explicitly labelled as having no functional change, and one entry that is nothing but links to an external release-highlights page. The actual release notes live on the project's documentation site, not here.
◆ Where it's heading
What can be read from these tags is infrastructure maintenance rather than product direction: Go dependency updates, helm and kind and skaffold and cosign version refreshes, and regenerated swagger and applyconfiguration files kept in sync with CEL and webhook validation comments in the core API types. That last one is the only entry hinting at anything structural — CEL-based validation on the API types implies declarative validation moving into the CRDs — but the commit itself changes only generated output.
◆ Prediction
This feed does not carry enough to predict product direction; until final releases or their notes appear here rather than only candidate tags, any read of where Fission is heading would be guesswork.

7.5INFRA · APIS
incident.io's agent now runs your team's own tools, with a human approval before any change.
◆ Current state
Investigations, the agent that posts a root-cause hypothesis when an incident opens, is the center of incident.io; it went GA and then doubled its speed in September. In October the company pushed its agent skills out into coding harnesses, then opened Nexus to customers' own tools and know-how. The 10-28 release restates that extension model and adds an explicit step: any change the agent proposes waits for a human approval before it runs.
◆ Where it's heading
incident.io is turning its agent into a two-way integration point that can act, not just diagnose. Skills go out to developers' agents, internal tools and team context come in, and the approval gate is what makes write access acceptable during an incident. Dashboards, ticket sync and alert routing keep incident.io as the record the agent reads from and writes to.
◆ Prediction
Expect worked examples for common connected systems such as deploy or feature-flag tools, and Investigations that propose concrete remediation steps for approval. The entries do not say how extensions are built or priced.
