v0 by Vercel vs Depot
Side-by-side trajectory, velocity, and editorial themes.
v0 turns the agent into a real shell user — terminal commands, OAuth MCP, browser screenshots, all in two weeks.
v0 ships at very high cadence, mixing small daily fixes with substantive agent-capability work. The May releases gave the agent the ability to run terminal commands (with per-command permission prompts), cut sandbox startup time by 50%, added OAuth-authorized MCP server support in the platform API, and made Claude Opus 4.7 Fast a configurable model option. Surrounding work — Snowflake account picker, browser screenshots in previews, .riv file support, design-mode element screenshots — pushes v0 further into 'real builds, not just UI prototypes.'
v0 is moving from AI-assisted UI generation toward an AI coding agent that owns the full build-and-deploy loop. Terminal access, faster sandboxes, OAuth MCP, and tight Vercel/Snowflake integrations are platform plumbing for production work, not prototyping. Model coverage stays at the cutting edge — Opus 4.7 Fast landed as a selectable model the same week it was announced — and the bug-fix discipline shows a team treating v0 as a maintained engineering tool, not a demo surface.
Next likely move is longer-running or background agent work — scheduled runs, async tasks, or an agent that owns a Vercel project across days. The combination of terminal execution + sandbox speed + MCP is the foundation; what's missing is persistence.
Depot is rounding out Depot CI into a credible GitHub Actions alternative, and just shipped nested virtualization.
Eight of the last ten changelog entries are Depot CI updates: a new workflow summary page, environment-aware secret and variable variants, CLI commands for metrics, JSON status output, live log streaming, workflow listing and inspection, run cancel/rerun/retry/dispatch, and a DEPOT_JOB_URL env var in every job. Registry got pull-through cache improvements with provider presets. The dominant theme is filling in the feature surface a serious CI platform needs.
Depot is methodically closing the gap between its CI product and the incumbents. The recent run reads like a checklist: workflow UX, secrets, metrics, log streaming, scriptable CLI surface — the table-stakes ergonomics teams expect before migrating off GitHub Actions or CircleCI. The May 20 nested virtualization release expands what kinds of workloads Depot CI can host at all, not just how nicely it hosts them, which is a different and more aggressive move.
Expect more workload-expansion moves following the nested virtualization release — likely Android-specific tooling, deeper matrix/sharding UX (the workflow page already groups matrix failures), and continued CLI parity work. The secrets-and-variables variant model looks set up to grow into broader policy-as-code for CI configuration.
