WantzelWantzel AI Studio

Run and supervise coding agents in one workspace.

Launch agents, see what each is doing and step in when needed. Their work continues when you close the browser or restart the studio.

Agents use the same files, tickets, compiler and debugger you do. They can build, run and correct code without moving results between tools.

Studio is the paid product. The language and the Wantzel compiler remain open source under the MIT license.

Wantzel AI Studio in the browser: mcpserver.wz open in the editor with its tools block of two one-line tool declarations, add and greet, the explorer beside it and 'build ok' in the status bar.
A two-tool MCP server. The compiler generates the schema, argument handling and dispatch.

What it does

See it in use

A fleet at a glance

See each agent's role, model, ticket, current task, elapsed time and token use. Start more agents by role or give the fleet a plan.

The Fleet panel with 20 agents, all running: eight builders each on a ticket such as 'A word-count tool' and 'Add a stats tool', and more agents on review and test tasks, each with its engine and elapsed time.

Where every agent is

The map shows which agents are running, waiting, failed or done, and which agent started each helper. It returns after a studio restart.

The Agent Map panel: filters for all 20, running 20, waiting on a human 0, failed 0, done 0, and a row per agent with its profile, ticket, task and engine.

An agent asks; you answer

Questions appear with their available choices. Other agents continue while this one waits. You can answer now or after a restart.

The agent panel with a list of running agents; in the corner a card from one agent: 'The stats summary line: show the mean or the median?' with the buttons mean and median.

Debug the running program

Click a line to set a breakpoint, then step over, into or out. Inspect globals, arrays and records while the program is paused.

The debugger paused in primes.wz after a step from the breakpoint on line 20: the step bar at the top, the current line 21 marked, and the Variables view with the locals v = 200000, k and m.

Fix an error beside the code

Compiler errors appear while you type. Open one for an explanation and a tested fix, or give the error and its context to an agent.

A typo on line 50 of structures.wz marked in the margin; the explanation above it with the compiler message 'undeclared identifier: totlk', the relevant help sections and a table of causes and fixes.

Watch an agent work

Ask in plain words and watch the agent edit, build, run and correct the files in your workspace. Take over at any time.

The agent panel beside the editor: a list of twenty running agents, one of them open with the ticket it was given and the rules it starts with, and the engine and model in the status line.

Describe a program

Type what you want in an empty file and press Ctrl+Enter. An agent writes, compiles, repairs and runs the program. Only code that compiles is written to the file.

table.wz after Ctrl+Enter: the description has become a working program that prints the times table of 10, and the console below shows its output from 1 x 10 = 10 to 10 x 10 = 100.

Give each agent a role

Profiles combine a role with its starting instructions. Use the included builder, tester and reviewer profiles, edit them or create your own.

The profiles list with builder, tester, reviewer, refactorer, documentation and UI/UX frontend; builder is open with its one-sentence role and the primer it starts with.

Browse application data

Connect to an application that exposes tables over MCP. Filter rows and edit allowed fields through the application's own validation.

The Database panel connected to a small demo app with three tables; the books table open as a grid of 24 rows, and the first row's fields beside it with the editable ones marked.

Work from a ticket

Search, read and update tickets beside the code. Give one to an agent and it writes, compiles and records the result in the work log.

The ticket panel: a quick-add line, a search field and eight tickets with their number, priority and title; T-0008 'A word-count tool' is open below with Open as Document and Give to Agent.

Review project history

Browse commits as a graph with each message, hash, author and time.

The history panel listing six commits with message, short hash, author and date.
