What is Rivet?
Rivet is repositioning its actor platform as the cheap runtime layer for coding agents.
Rivet is shipping at a high cadence and pivoting its narrative toward AI-agent infrastructure. The recent window includes agentOS v0.2 (a WebAssembly-powered, low-cost alternative to sandboxes for running coding agents), Rivet Compute (serverless hosting for actors), a Rust rewrite of Secure Exec, and new Rust and Effect SDKs for Rivet Actors. The pitch is that agents need a lightweight Linux VM, not a heavy sandbox.
What is Tigris?
Tigris positions object storage as the substrate for AI agents, with forks and snapshots as the hook
The Tigris feed is a technical blog that mixes genuine feature launches with engineering essays and demos. Real product releases in this window — soft delete, streaming-tar bundles, expanded lifecycle rules — sit alongside deep-dive posts (objgit, Kefka, agent-shell, LangGraph agent evaluation) that showcase Tigris's fork and snapshot primitives rather than announce shipped features.
Rivet vs Tigris: editorial side-by-side
Rivet
7.5DEVOPS
Rivet is repositioning its actor platform as the cheap runtime layer for coding agents.
◆ Current state
Rivet is shipping at a high cadence and pivoting its narrative toward AI-agent infrastructure. The recent window includes agentOS v0.2 (a WebAssembly-powered, low-cost alternative to sandboxes for running coding agents), Rivet Compute (serverless hosting for actors), a Rust rewrite of Secure Exec, and new Rust and Effect SDKs for Rivet Actors. The pitch is that agents need a lightweight Linux VM, not a heavy sandbox.
◆ Where it's heading
Rivet is layering an agent-runtime stack on top of its actor/edge-compute core: agentOS provides isolated, fast-booting environments for coding agents at a fraction of sandbox cost, Rivet Compute removes infra management, and the multiplying SDKs (Rust, Effect, earlier SQLite) widen language and framework reach. The strategic bet is to become the default execution substrate for coding agents by undercutting incumbent sandboxes on cost and cold-start.
◆ Prediction
Expect agentOS to keep hardening (more language runtimes, orchestration features) and Rivet to push the cost-versus-sandbox comparison as its primary wedge, likely with managed-platform and pricing milestones next.
Tigris
6.3DEVOPS
Tigris positions object storage as the substrate for AI agents, with forks and snapshots as the hook
◆ Current state
The Tigris feed is a technical blog that mixes genuine feature launches with engineering essays and demos. Real product releases in this window — soft delete, streaming-tar bundles, expanded lifecycle rules — sit alongside deep-dive posts (objgit, Kefka, agent-shell, LangGraph agent evaluation) that showcase Tigris's fork and snapshot primitives rather than announce shipped features.
◆ Where it's heading
Tigris is bending an S3-compatible object store toward AI-agent workloads: per-tenant bucket forks, copy-on-write disposable environments, and snapshotting recur across both its releases and its demos. The through-line is making storage cheap to fork and roll back so each agent or tenant gets an isolated, reversible workspace — with a provider-agnostic SDK aiming to carry that model beyond Tigris itself.
◆ Prediction
Expect Tigris to keep hardening data-protection primitives (soft delete, lifecycle, snapshots) and to lean further into agent-oriented tooling built on bucket forks; the provider-agnostic SDK is the move to watch for reach beyond its own store.
