It asks.
The agent proposes a plan, then lands a question in the chat box with its choices, then asks before it pushes.
The coding app by Soumya Chakraborty
Supercharged
coding agent for Mac, Windows & Linux
Hydra is on from your first chat: one chat leads a team of heads that work in parallel, each in a copy of your project, and their work lands as one merge. Codex, Claude, Cursor, OpenCode, Grok, Antigravity, Copilot, Command Code, Pi, DeepSeek, Meta and Z.ai, in one Liquid Glass window on your own subscriptions. Free and open source.
One chat, many heads.
Hydra is on from your first chat. The lead writes the briefs, sends heads out in parallel, each in a copy of your project, checks their work when they report back and lands it as one merge.
Meet Hydra.
The lead sends out Hank, Walter, Ada and the rest, hears back from each one as a badge in the chat, and keeps the team's panel at hand. Plans and questions come to you the same way, with a wave along the top when they wait on you.
Pair a strong lead with quick heads.
A pair says which model leads and which model, or which provider, runs the heads: a Claude lead over Gemini or OpenCode heads, picked straight from the model picker. Without a pair the heads take the chat's model at a working effort, so a Max lead sends out medium heads.
Effort, fused.
In a pair the slider is the lead's: its track blends the lead's colour into the heads', and says what effort the heads run at.
Panels that snap.
The team's panel, every head popped out of it and the usage panel dock to slots beside the chat, three a side on a 16-inch display, fewer on a smaller one. Drag one to any slot to reorder or swap, and let heads pop out on their own while there is room.
Just some of the highlights
The real app, mid-work: asking, queueing, reviewing, and the palette.
Queue what's next.
Type while it works. Follow-ups line up above the chat box and go out one after another when the turn ends.
A diff for every turn.
Each reply is captured as a checkpoint. Read the change in place, revert the turn, or rewind the whole thread.
Every action, one keystroke away.
Threads, projects and every command, from ⌘K, over whatever you were doing.
Recipes for a team
Hydra's cookbook: ready-made pairs with a lead, its heads and an effort for each side, from the providers you have signed in.
Hydra, explained where you switch it on
The first time you turn Hydra on, a short intro shows what the lead and its heads will do before anything runs.
Threads, when you want them
Hide the sidebar and the chat has the whole window; the Threads button floats the list back over it.
Bring your own agent.
Swarm Code runs the command line tools you already have installed and signed in, on the subscriptions you already pay for. No keys to paste, no middleman, no markup.

Every limit, one popover.
Click the ring beside the send button and every window you pay for is there: each rolling limit with its reset, and the credit left on a pay-as-you-go key. In a Hydra pair the lead's provider stacks over the heads'.

- Plan limitsCodex, Claude, Antigravity, Copilot, Command Code and Z.ai: every rolling window, how much of it is used and when it resets.
- CreditsDeepSeek and Command Code keys show the balance left on them.
- Lead and headsA pair across two providers stacks both: the lead's limits first, then the heads'.
- Every account at onceSettings › Providers shows the same limits for every signed-in provider on one page.
- Or keep it openSwitch on the usage panel in General settings and the same limits float beside the chat, across from the heads; the popover's expand button opens it any time.

Swarm Code is a Mac app for the agents on your Mac. Everything that would turn it into a service, an account or a data pipeline is not on the roadmap, and not in the binary.

Frequently asked
questions
Swarm Code is the coding app by Soumya Chakraborty: a native desktop app that drives the coding agents you already have installed. It gives Codex, Claude, Cursor, OpenCode, Grok, Antigravity, Copilot, Command Code, Pi, DeepSeek, Meta and Z.ai one shared window with projects, threads, streaming replies, approvals, diffs, git and a terminal.
Yes. Swarm Code is free and open source under the MIT License. You pay your agent providers as you already do; Swarm Code never sits in between, never proxies a request and never adds a markup.
Yes, all of it. The app lives on GitHub, with macOS releases on Swarm-Code-Release and Windows & Linux releases on SwarmCode-Dessktop-Release. Read it, build it, or contribute.
Not for Codex, Claude, Cursor, OpenCode, Grok, Antigravity, Copilot, Command Code or Pi: sign in once in your terminal, for example codex login, claude auth login, cmd login or pi then /login, and Swarm Code uses that session and your subscription. DeepSeek, Meta and Z.ai talk to their APIs directly, so those three take a key, stored securely on your machine.
Swarm Code supports macOS (Apple silicon, macOS 26 or later), Windows 10 & 11 (64-bit x64), and modern Linux distributions (via standalone x86_64 AppImage and Debian/Ubuntu .deb packages). All platforms share the full Hydra parallel agent workflow and terminal integration.
Only what your agents send to their own providers. Swarm Code has no telemetry, no analytics, no account and no cloud sync. Remote access, mobile apps and a web client are left out on purpose. Your threads, checkpoints and settings stay on your Mac.
After every turn Swarm Code records a hidden git checkpoint of your project, so each reply comes with a diff and a revert button, and a thread can be rewound to any earlier turn. A new thread can also start in its own git worktree, a separate copy of the repository on its own branch, so several agents can work on one project at the same time without touching each other's files.
Hydra turns one chat into a team, and it is on from your first chat. The agent becomes the lead: it writes the briefs, sends helper agents called heads out in parallel, each in its own copy of your project, checks their work when they report back and lands it in your checkout as one merge. A pair sets which model leads and which model, or which provider, runs the heads, a Claude lead over Gemini heads for example, with one effort slider fused for both; without a pair the heads run on the chat's model at a working effort. Every head can have a panel that floats beside the chat, panels snap to slots you can reorder, and right-clicking the Hydra mark switches it off for a chat.
Yes. The ring beside the send button opens a popover with the context window, every rolling limit of your plan with its reset time, and the credit left on a pay-as-you-go key. Codex, Claude, Antigravity, Copilot, Command Code and Z.ai report plan limits; DeepSeek and Command Code report credits. In a Hydra pair across two providers the lead's limits stack over the heads'. Switch on the usage panel in General settings to keep them floating beside the chat, or open that panel from the popover's expand button. Settings › Providers shows the same for every signed-in account at once.
