Vercel · Agent stack · Beta
A demo agent answers questions on a laptop. A working one has to reply on WhatsApp at midnight, write the lead to Salesforce, and stop before it offers a discount. eve is an open-source framework for that: the agent’s job in plain files, tools in TypeScript, channels like WhatsApp, Slack and Teams, and approval gates that pause for a person. eve is in beta under Vercel’s beta terms.

The problem
What eve is
Facts from Vercel’s own pages, checked on 16 October 2026. The sources are at the end of this page.
How it works
Five steps. Sessions run on Workflows, so a conversation survives a restart or a new release and waits for as long as an approval takes.

Step by step
Write
Write the job in plain files
Instructions and skills in markdown, each tool in its own TypeScript file. The file name is the tool name.
Connect
Connect WhatsApp, Slack or Teams
Each channel is a file in the agent’s folder. Schedules start sessions without a message.
Start
A message starts a session
Each message is a turn. The session keeps its place between turns.
Work
The agent calls your tools
It looks up the booking, writes to Salesforce through Connect, or runs code in a sandbox.
Approve
A refund or a discount pauses the session until someone approves. Jev can clear routine calls first.
How it fits together
Customers write on WhatsApp, staff on Slack or Teams. The eve agent answers, calls Salesforce and your own systems, and uses AI Gateway, Sandbox and Workflows underneath. All of it is open source and in beta.

Use cases · worked examples
How eve fits into the work of the industries we serve, one step at a time.
Example 1 · Real estate, Kochi · Infographic
Today: Enquiries arrive on WhatsApp late at night. By morning half the buyers have asked another builder, and the ones who reply ask for a discount nobody can approve at midnight.
After: An eve agent answers on WhatsApp, books site visits and writes each lead to Salesforce. Any discount request waits for the sales manager’s yes.
Worked example, step by step
The buyer gets an answer at 23:10, and no price is promised without the manager.
Example 2 · Hotel apartments, Abu Dhabi · Infographic
Today: Guests send towel requests and refund demands to the same WhatsApp number. Reception answers both in arrival order, so the refund waits behind ten towel requests.
After: Jev clears routine tool calls such as a housekeeping request, so they run at once. Anything that moves money pauses for the duty manager in Teams.
Worked example, step by step
Towels arrive without a queue, and every refund has a manager’s name on it.
Example 3 · Couriers, Jeddah · Infographic
Today: Every morning a coordinator goes through yesterday’s failed deliveries one by one, calls each customer, and asks a supervisor before waiving any fee.
After: A morning schedule starts the agent. It pulls failed drops from the database, sends each customer a rebook link by SMS, and asks ops in Slack only about fee waivers.
Worked example, step by step
Customers have a rebook link before nine, and ops decides only the exceptions.
