A side-by-side editorial comparison of Infisical and Split.io — release velocity, themes, recent moves, and the top alternatives to consider.
Infisical vs Split.io: at a glance
What is Infisical?
PAM and PKI now take up most of the lines in Infisical's release notes.
Six releases in two weeks, each a flat PR list with no narrative. The recurring feature work is privileged access management — Redis account types and web access, filling account fields from a pasted connection string, machine identity access — and PKI, which gained AWS Private CA as an issuing authority and SCEP enrollment for Microsoft Intune. Secret management itself mostly appears as rotation coverage for Cloudflare API tokens and R2 access keys.
What is Split.io?
Split FME's March releases pull feature flags fully into the Harness DevOps platform.
Split.io now ships under the Harness Feature Management & Experimentation (FME) brand, and the substantive activity is captured in the rolled-up release-notes page rather than per-release entries. The March 2026 wave landed three real ships: Policy As Code (OPA) for FME Feature Flags, Feature Flag Archiving with RBAC and pre-archive checks, and the GA of FME steps in Harness pipelines covering full flag lifecycle management. The rest of the recent feed is scraper artifacts — page chrome captured as titles.

Infisical
5.0INFRA · APIS
PAM and PKI now take up most of the lines in Infisical's release notes.
◆ Current state
Six releases in two weeks, each a flat PR list with no narrative. The recurring feature work is privileged access management — Redis account types and web access, filling account fields from a pasted connection string, machine identity access — and PKI, which gained AWS Private CA as an issuing authority and SCEP enrollment for Microsoft Intune. Secret management itself mostly appears as rotation coverage for Cloudflare API tokens and R2 access keys.
◆ Where it's heading
Infisical is assembling a credential platform rather than a secrets store, and it is doing so without a single headline release — each pillar arrives as two or three PRs per version. PKI is furthest along: issuing from an external AWS authority and enrolling devices through Intune puts it in territory previously held by dedicated certificate products. A third thread, the agent proxy, is accumulating the parts a product needs before launch — a Google Workspace service template, last-used timestamps, and adoption telemetry for proxied services.
◆ Prediction
The agent proxy is the thread most likely to get a real announcement; service templates and usage telemetry landing now are the groundwork a launch requires.
Split.io
0.6INFRA · APIS
Split FME's March releases pull feature flags fully into the Harness DevOps platform.
◆ Current state
Split.io now ships under the Harness Feature Management & Experimentation (FME) brand, and the substantive activity is captured in the rolled-up release-notes page rather than per-release entries. The March 2026 wave landed three real ships: Policy As Code (OPA) for FME Feature Flags, Feature Flag Archiving with RBAC and pre-archive checks, and the GA of FME steps in Harness pipelines covering full flag lifecycle management. The rest of the recent feed is scraper artifacts — page chrome captured as titles.
◆ Where it's heading
FME is becoming a first-class part of the Harness DevOps surface rather than a standalone feature-flag tool. Pipeline-native flag operations, policy-as-code governance, and archiving as a managed lifecycle state all reflect a single direction: feature flags as a governed, audited, and pipeline-integrated component of the deployment system. The standalone Split UX is fading into Harness conventions.
◆ Prediction
Expect more Harness-platform conventions to land on FME — RBAC unification, environments and pipelines parity, OPA policy templates shipped out of the box, and observability tying flag changes back into deploy-failure/MTTR dashboards. Standalone-Split UX surfaces will likely be retired further.
