What is Insomnia?

Insomnia ships steady client polish — Git Credentials, Cloud Sync controls, gRPC template tags, portable Windows binary.

The April release notes batch a set of usability improvements rather than a single headline feature: the Git Credentials modal got everyday-use polish, Cloud Sync now lets users delete files locally and remotely (or just locally), the design-to-debug switching preserves user data better, gRPC requests support template tags and multi-file proto imports, and Windows users get a portable binary on the GitHub releases page. The product surface visible in the GitHub README header now lists an 'MCP Client' alongside the long-standing API client, design, mocking, and CLI features.

What is Retool?

Retool pushes self-hosted 4.0 to stable, laying RBAC and security groundwork for enterprise.

Retool's self-hosted line dominates this window: version 4.0 has reached the stable channel, carrying an automatic permissions-database migration that prepares the platform for Role-Based Access Control, with an upgrade FAQ to guide existing deployments. Around it, admins gain new controls — customizable Content Security Policy for apps — and a way to buy additional AI credit packs from organization settings. The cadence is dense and operational, centered on shipping and de-risking the 4.0 upgrade for self-hosters.

Insomnia ships steady client polish — Git Credentials, Cloud Sync controls, gRPC template tags, portable Windows binary.

◆ Current state

The April release notes batch a set of usability improvements rather than a single headline feature: the Git Credentials modal got everyday-use polish, Cloud Sync now lets users delete files locally and remotely (or just locally), the design-to-debug switching preserves user data better, gRPC requests support template tags and multi-file proto imports, and Windows users get a portable binary on the GitHub releases page. The product surface visible in the GitHub README header now lists an 'MCP Client' alongside the long-standing API client, design, mocking, and CLI features.

◆ Where it's heading

Under Kong's ownership, Insomnia is keeping the open-source desktop client alive with a steady stream of small improvements while the strategic surface area appears to expand into the MCP-client space — a meaningful nod to the agentic-tooling category. The April releases focus on fit-and-finish for existing power users (Git, gRPC, multi-platform packaging) rather than category expansion, suggesting a deliberate split: keep the desktop client trustworthy for paid customers, while exploring AI-adjacent surfaces upstream.

◆ Prediction

Expect MCP-client features to appear in subsequent changelogs once the surface stabilizes — that's the most directional move hinted at by the README. On the existing client, watch for further Git workflow polish and an eventual official Linux portable binary to match the new Windows one.

Retool pushes self-hosted 4.0 to stable, laying RBAC and security groundwork for enterprise.

◆ Current state

Retool's self-hosted line dominates this window: version 4.0 has reached the stable channel, carrying an automatic permissions-database migration that prepares the platform for Role-Based Access Control, with an upgrade FAQ to guide existing deployments. Around it, admins gain new controls — customizable Content Security Policy for apps — and a way to buy additional AI credit packs from organization settings. The cadence is dense and operational, centered on shipping and de-risking the 4.0 upgrade for self-hosters.

◆ Where it's heading

Retool is advancing its self-hosted enterprise story — RBAC groundwork, CSP customization, and a managed upgrade path point to a focus on admin control and security posture for regulated, self-hosted deployments. Separately, AI usage is becoming a metered, separately-purchased resource. The platform is maturing self-hosted governance while turning AI into a billable line item.

◆ Prediction

Expect Role-Based Access Control to ship as a full feature on the back of the 4.0 permissions migration, plus continued 4.0 hardening — stable patches and more admin security controls.
