Rillet triples shipping speed with eve agents on Vercel

Rillet, an AI-native ERP platform, has tripled its shipping rate over the past three months by deploying AI agents on Vercel. The company’s two-person frontend team, led by Anthony Liang, uses eve, Vercel’s open-source agent framework, to automate workflows ranging from customer fixes to code review. This approach allowed the team to close more than 800 Linear tickets in their first four months and ship customer-requested changes to production in as little as two hours.

Standardizing agents with eve

Anthony Liang chose eve to standardize agent development across Rillet, moving away from disparate SDKs and open-source tools that required custom integration logic. In eve, an agent is defined as a directory where instructions, tools, and skills are co-located. This structure allows non-technical team members to shape agent behavior using markdown instructions, while developers define tools in TypeScript files. The agents are deployed to Vercel without behavioral changes, managed within a single company-controlled Vercel organization.

To secure integrations, Rillet uses Vercel Connect to provide agents with access to Slack and Linear. Connect supplies short-lived tokens at runtime, eliminating the need for long-lived provider secrets in individual applications. This setup reduces credential maintenance and limits the impact of potential token leaks.

Automating customer requests end-to-end

Rillet replaced fragmented request processes with a streamlined pipeline where customer success teams use a Chrome extension to highlight issues and describe changes. An eve agent captures this context and, if the change is safe, hands it to a coding agent that writes the specification, implements the change, and opens a pull request. The agent also spins up a sandboxed browser to test the change and attaches screenshots as proof. Anthony reviews and merges the pull requests, with agents resuming sessions to address any requested changes.

The company’s CPA team uses an in-house agent named Nebula to ship customer requests within two hours. Rillet’s CEO noted that the company shipped more in recent weeks than in the entire first half of 2026, with customers reporting that the speed of changes has "completely ruined" their expectations for software vendors.

Managing models and access

As more employees built agents, Rillet adopted AI Gateway to route model requests to providers like Anthropic and OpenAI through a single integration. In eve, builders select models by setting a string in the agent’s configuration, allowing them to switch models without changing the underlying integration. AI Gateway automatically handles authentication for agents deployed on Vercel and provides usage breakdowns to help track costs and model selection.

To manage builder access, Rillet implemented Enterprise Managed Users, enabling sign-in via Google Workspace single sign-on with company-managed accounts. Directory Sync automatically adds or removes access based on assignments in Rillet’s identity provider, ensuring account administration aligns with company directory changes.

Future plans

Anthony is developing an "agent factory" to scale this pipeline to larger features. This system includes agents that write PRDs and technical specs, and others that connect to Linear boards, Miro diagrams, and knowledge bases to provide context. By leveraging subagents and delegation built into eve, Rillet aims to add specialized agents as directories within the same framework, bringing the same speed to internal tooling as it does to its core product.
