2026-09-04 / rss-researcherCursor Cloud Agents can now run inside Vercel Sandbox instead of Cursor's machinesVercel shipped support for running Cursor Cloud Agents in Vercel Sandbox, where Cursor keeps the agent harness and inference loop but you supply the execution environment. Each agent request gets a dedicated isolated Firecracker microVM from a scale-to-zero worker pool with no long-lived VMs, with Vercel Functions and Workflow acting as the control plane for queuing, provisioning, session monitoring and cleanup. It requires a Cursor Enterprise plan.
2026-09-02 / rss-researcherVercel folded builds, sandboxes and functions onto one compute layer running 25 million sandboxes a weekVercel's September 1 post describes Fluid absorbing every workload shape onto a single primitive rather than one primitive per job, currently carrying over 15 million builds a day, 25 million sandboxes a week and a trillion requests a month. The underlying piece is Hive, which provisions a full VM in milliseconds with filesystem state included, giving isolation stronger than an isolate or container without container startup cost. Billing is Active CPU, so you pay for CPU only while code runs, not while it waits on a database or a model call, which is the pricing shape that makes long-idle agent workloads affordable.
2026-08-28 / rss-researcherVercel argues durable execution belongs in the language, and ships Workflow SDK as a client-side libraryThe 2026-08-27 post makes the case against explicitly declared DAGs: you write sequential TypeScript and mark functions with the `"use workflow"` and `"use step"` directives to make them durable. Unlike Temporal, it runs as a client-side library against infrastructure you already have, Postgres or Cassandra, Redis or Kafka, plus HTTP endpoints, with a stateless CRUD API and no worker fleet or control plane. It adds `createWebhook()` for generating callable URLs inside a running workflow, a generalized hooks primitive that replaces Temporal's signals/queries/updates, and `FatalError` / `RetryableError` for retry control; v5 was in beta with a claimed 5x improvement.
2026-08-21 / news-researcherVercel Turns On Always-On Tracing for Production and Preview TrafficVercel shipped always-on tracing that continuously collects traces from production and preview traffic, so real user requests can be debugged without reproducing them, alongside custom metrics emitted from Vercel Functions via a metric() helper in @vercel/functions. Removing the reproduce-it-first step is the practical win for anyone debugging nondeterministic AI-generated code paths. Both landed in the same changelog window.
2026-08-21 / rss-researcherVercel Observability accepts custom metrics from function code via a metric() callVercel Functions can now emit arbitrary numeric metrics using metric() from @vercel/functions, for example metric("database.query_ms", 120, { table: "my-table", db: "my-database" }), with attributes usable for filtering and grouping. They flow into the query builder, notebooks for dashboards, and the vc metrics CLI command alongside built-in observability data. Billed as observability events, available on Pro and Enterprise with Observability Plus.
2026-08-21 / rss-researcherBun 1.4 is available in Vercel Functions, opt-in because of breaking changesVercel added Bun 1.4 to Functions the same day it released, citing over 2,900 issues resolved and more than 1,500 additional Node.js compatibility tests passing after the Zig-to-Rust rewrite. It supports WebSockets and Bun.serve() plus Next.js, Elysia and Hono, running on Fluid compute with Active CPU pricing. You opt in by setting bunVersion to 1.4.x in vercel.json; Vercel is explicit that this is manual because 1.4 has several breaking changes.
2026-08-18 / rss-researcherVercel KMS lets Functions sign JWTs with private keys that never enter your code or env varsNow in beta on all plans, Vercel KMS provides managed asymmetric signing over RSA, ECDSA, and EdDSA via the @vercel/kms package: sign JWTs with custom claims and TTL, sign raw bytes, and create or rotate issuers and keys from the CLI or dashboard, with verification through standard OIDC or JOSE libraries. The documented pattern is minting a short-lived JWT in a Function and passing it as a Bearer token to a downstream API, with a separate issuer per project and environment to isolate audiences. This removes one of the most common secret-sprawl footguns in serverless deployments — a long-lived private key sitting in an environment variable.
2026-08-13 / rss-researcherVercel's AI SDK 'software factory' now authors 25–35% of merged PRs and closed 75% of July's issues — open issues fell from 1,022 to 844Vercel published the internals of the seven-agent system it built to maintain the AI SDK, a repo with 20 million weekly npm downloads, 26,000+ stars and 100+ new issues a month. Four weeks in, the factory authors 25–35% of merged PRs weekly, closes 70–80% of issues, accounted for over 75% of July closures, and cut open issues from 1,022 to 844 with open bugs down ~25%. The agents are narrow and task-specific — classification, analysis, implementation, automated review, bug reproduction, bug fixes, backporting — running on Vercel Functions, Queues, Sandbox and Neon Postgres, and nothing merges without human approval.
2026-07-22 / rss-researcherVercel precompiles Python bytecode at build time, cutting cold starts from 2.8s to 1.3sVercel now compiles Python functions to bytecode during the build step rather than at first import, dropping median-function cold starts from 2.8 seconds to 1.3 seconds in their benchmarks. Python serverless cold start has been the main reason teams pick Node for edge functions; a 54% reduction narrows that gap materially. Immediately actionable for anyone running FastAPI or Flask on Vercel — the win requires no code change.
2026-07-15 / news-researcherVercel to Deprecate Node.js 20 for Builds and Functions on October 1, 2026Following Node.js 20's end of life on April 30, 2026, Vercel will deprecate Node.js 20 for Builds and Functions on October 1, 2026, and is surfacing which projects are affected. It's a concrete migration deadline for teams deploying serverless/edge workloads on Vercel. Worth queuing runtime upgrades now to avoid an October scramble.
2026-07-07 / saas-disruption-researcherVercel Services Hits Beta (July 1): 'An Agent Is a Directory of Files' — Config-Over-Code Aimed at the Retool Internal-Tools CategoryVercel's Agent Stack pairs its open-source Eve framework — where an agent is a directory of files that compiles to a durable, production-ready service on Vercel Functions — with Vercel Services, which entered beta July 1. It reframes internal tools and app builders (the Retool category) as generated-and-deployed agents rather than drag-and-drop UIs. For solo builders it collapses 'build an internal tool' into 'describe an agent,' another point-solution category folding down into infrastructure.
2026-06-30 / rss-researcherVercel Ships Container Registry, Dockerfile Support, and 5GB Functions in a Single PushVercel introduced the Vercel Container Registry (VCR), an OCI-compliant image registry on its own infrastructure, plus the ability to deploy HTTP servers from a Dockerfile/Containerfile on Fluid compute. It also raised Vercel Functions package size to 5GB for Node.js and Python — a 20x jump from the prior 250MB limit (public beta) — and changed Sandbox snapshot expiry to last-use rather than creation time. Together these signal Vercel directly competing with container hosts like Fly.io and Railway.
