v2.2.33 — Canvas, Projects and the Vault

One AI. Every model.
Yours.

Your providers. Your credentials. Your data. Your cost. Anvil runs in your terminal, drives from your browser, and remembers across sessions — with a mind map of everything it's thinking. And a marketplace of everything the community builds for it.

You

Add a merge_sorted helper to src/utils.rs that merges two sorted slices, with a unit test. Then run the tests.

Anvil

I'll add a merge_sorted function with a two-pointer merge and a covering test. First, let me look at the file.

read_file {"path":"src/utils.rs"}

edit_file {"path":"src/utils.rs", …}

Anvil

Added merge_sorted — O(n+m), stable across duplicates:

RUST/// Merge two already-sorted slices into one sorted `Vec`. pub fn merge_sorted(a: &[i32], b: &[i32]) -> Vec<i32> { let mut out = Vec::with_capacity(a.len() + b.len()); let (mut i, mut j) = (0, 0); while i < a.len() && j < b.len() { if a[i] <= b[j] { out.push(a[i]); i += 1; } else { out.push(b[j]); j += 1; } } out.extend_from_slice(&a[i..]); out.extend_from_slice(&b[j..]); out }

Anvil

Now let me run the tests to prove it works.

bash cargo test merge_sorted

Anvil

running 1 test
test utils::tests::merges_sorted ... ok

test result: ok. 1 passed; 0 failed; 0 ignored
All green — the test covers interleaved values, empty inputs, and duplicates.

Why Anvil

Other assistants come with a leash.
Anvil is the inverse.

Most AI coding tools route through one vendor, hold your keys, and phone home. Anvil hands you the reins — every layer is yours to control.

🔌

Any provider

Anthropic, OpenAI, Gemini, xAI, Ollama, and 30 more. Switch mid-session with /model.

🔑

Your keys

Bring your own API keys, held in a local encrypted vault. Anvil never sees a key it didn't get from you.

🗄️

Your data

Sessions, memory, and your mind map live on your machine as plain files. They travel with you.

🛰️

Zero telemetry

No phoning home. What happens in your terminal stays in your terminal.

Teams & fleet

Expertise that costs nothing
until you actually use it.

A real agent library is dozens of specialists. Telling the model about all of them costs thousands of tokens of roster on every single turn — spent before any work happens, and growing every time you add an agent. Anvil refuses that trade.

🧮

Twelve names, not a roster

The model sees twelve squad names and a one-line brief each — about 300 tokens, and that cost is fixed. No agent names, no counts. Add a hundred specialists and it does not grow by a line.

🎯

Ask for a capability

You ask for security testing, not for a name you had to memorise. The host resolves the concrete specialist from the full roster and loads it for that job — then lets it go.

📦

Grow it from the marketplace

Install a whole new squad here and it becomes routable immediately — no Anvil update, no waiting on a release that knows your team.

⛔

An empty squad says so

Ask for a capability nobody on the team has and Anvil refuses — rather than quietly handing the job to a general-purpose agent and letting you believe a specialist did it.

📡

Every machine you own

/fleet sends one task to every eligible Anvil on your account and collects the answers — routed by capability, so the work lands somewhere that can actually run it.

📋

No silent half fan-out

It names what was sent, what was refused, and who was never eligible. A fan-out that reports only its successes looks identical to one that lost half your fleet.

The mind map

It thinks in a map.

A living, force-directed graph of your work — wired into Anvil's memory so it reflects what it's actually learning. Drive it from the browser: drag anything, zoom to the cursor, click any node for its full notes.

Force-directed

Nodes repel so the graph stays readable at hundreds of nodes.

🧠

Memory-aware

Today's memories auto-populate; toggle to a color-coded Memory Graph.

✦

With atmosphere

An ambient starfield drifts behind it — on the web and in the terminal.

Live control

Terminal and browser, one session.

Start in the terminal, hand off to a paired browser tab, and back again — it's the same live session the whole time, never a copy. Nothing is lost in the handoff.

✦ Pair a browser with one command; drive the exact session you're running.
✦ The web viewer renders like a product — message cards, glowing code panels, real markdown.
✦ Hand off without flashing or losing history; wake the terminal and it's all there.
