What is Railway?

Railway's weekly cadence is building a PaaS for AI agents: MCP, Cloud Agents, no-barrier entry.

Railway ships at roughly weekly cadence across two clear vectors: agentic infrastructure and frictionless entry. Cloud Agents—persistent, resumable background agents—are now live across dashboard, CLI, and mobile. Alongside that, Railway has progressively eliminated signup friction: no-account deployment for sites and databases, free Sandboxes, and now free VMs, all on the same production-grade stack.

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.

Railway's weekly cadence is building a PaaS for AI agents: MCP, Cloud Agents, no-barrier entry.

◆ Current state

Railway ships at roughly weekly cadence across two clear vectors: agentic infrastructure and frictionless entry. Cloud Agents—persistent, resumable background agents—are now live across dashboard, CLI, and mobile. Alongside that, Railway has progressively eliminated signup friction: no-account deployment for sites and databases, free Sandboxes, and now free VMs, all on the same production-grade stack.

◆ Where it's heading

Railway is converging its entry-tier and production-tier moves on a single architecture: Cloud Agents as the deployment primitive, MCP as the agent-accessible interface, and a growing roster of AI coding tools (Claude, ChatGPT, Grok, OpenCode) wired directly into that stack. The bet is that developers building agentic applications will want infrastructure that agents can deploy to and operate autonomously. Database management maturity (MySQL/Redis/Postgres HA, PITR, one-click major version upgrades) provides the backend layer that agentic workloads depend on.

◆ Prediction

The next likely move expands Cloud Agents further—persistent memory, inter-agent communication, or dedicated agent compute pricing. Each new AI coding tool integration (OpenCode is the latest) follows the same pattern; expect more.

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.
