What is Currents?

Currents is building the agent-native CI layer: machine-readable failure context, IDE integration, scoped API tokens.

Currents is a Playwright/Cypress test observability platform that has made two explicitly agent-targeted moves in recent months: a shareable .md endpoint for test failures (structured failure context fetchable by AI agents without a Currents login) and a VS Code/Cursor extension that puts CI run history inside the IDE where AI agents can act on it. Personal Access Tokens — scoped per-user API tokens replacing the shared org key — just landed this week, addressing a real security gap in the API access model.

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.

Currents is building the agent-native CI layer: machine-readable failure context, IDE integration, scoped API tokens.

◆ Current state

Currents is a Playwright/Cypress test observability platform that has made two explicitly agent-targeted moves in recent months: a shareable .md endpoint for test failures (structured failure context fetchable by AI agents without a Currents login) and a VS Code/Cursor extension that puts CI run history inside the IDE where AI agents can act on it. Personal Access Tokens — scoped per-user API tokens replacing the shared org key — just landed this week, addressing a real security gap in the API access model.

◆ Where it's heading

The product is converging on a position as the CI context layer for AI coding agents. Each major feature — shareable failure links with a .md format for agent consumption, IDE extension with agent-fix flow, Linear integration for structured failure triage — points at the same thesis: that CI failure remediation will increasingly be handled by AI agents, and Currents wants to be the system those agents pull context from. The pricing restructure (self-serve Business plan, cheaper per-user rates) lowers the entry barrier for teams adopting this agent-augmented workflow.

◆ Prediction

The IDE extension will likely expand to support more agentic actions beyond 'fix failure' — expect quarantine, tagging, and re-run controls. The .md shareable context format will likely become a formal API surface with authentication options for enterprise use.

◆ 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.
