GRID
Launch multiple project terminals in one compact workspace.
Desktop workspace for coding agents
13x faster.13x cheaper.13x better.
Map your codebase locally, send agents only the context that matters, and run every terminal, rig and agent from one workspace. Faster runs. Fewer tokens. Cleaner control.
vibe coding is chaos. 13x is control.
- ~96%
- fewer tokens per run*
- 100% local
- no code upload, no telemetry
*Typical context-packet size versus sending the whole repo — estimated, varies by repo & task. The desktop app runs locally; an account is only needed for Pro billing.
live · the whole workflow
One prompt in. A finished workflow out.
Type the task once. 13x fans it out across a graph of agents — built in parallel by Claude, GPT and Gemini — picks the best, runs the tests, and loops back on a failure until it passes. Watch it run, or switch the tab to ship a PR, rank a page, triage support, or draft content.
One prompt fans out across a graph of agents — built in parallel, judged, tested, and looped until it passes.
why 13x
FASTER
Type one prompt and 13x splits it across a rig of agents — each on its own branch, all working in parallel. One task, many hands.
CHEAPER
13x Map builds a local graph of your repo and sends agents only the files and symbols that matter — not the whole codebase. Smaller context packets, far fewer wasted tokens.
BETTER
Relay chains a task through the right model at every step — plan, implement, review — pausing at a checkpoint before each handoff. Control instead of chaos.
faster · rigs
One prompt. A whole rig, working in parallel.
Type the task once. 13x plans it, splits it into per-lane sub-prompts, and dispatches each to its own agent on its own branch — so four things ship in the time one used to.

cheaper · map
Stop sending the whole repo.
The code map ranks your repo by relevance to the task and ships agents a small context packet — only the files and symbols that matter. That’s not just cheaper: the whole-repo dump is exactly what dilutes context and makes models lose the thread. A lean, relevant packet costs a fraction of the tokens and produces sharper output.

better · relay
One task, the right model at every step.
Relay runs a task through a chain of agents — plan, implement, review — and pauses at a checkpoint before each handoff. Each step has its own model and prompt; its extracted answer flows into the next through the {prev} placeholder, not raw terminal scrollback.

what 13x does
available now
01
RIGS
Save repeatable setups with named slots, roles and startup commands.
PULSE
See which sessions are active, idle, done, stopped or broken — real turn state from agent hooks.
MAP
Build a local codebase graph and generate smaller context packets.
BLAST RADIUS
See the direct and transitive dependents of any change, with a verified rename verdict — and an honest gap where references resolve dynamically.
WORKTREES
Run each branch in its own checkout, with a semantic collision check git can't see.
CONTROL
Fan one relay across many worktrees with per-agent checkpoints and live cost.
RELAY
Chain agents so one model's extracted answer becomes the next one's context.

TRACE
LATERCapture what agents changed, why, and what needs review.
local-first
your code stays local.
13x is designed as a local desktop workspace first.
- No cloud indexing.
- No forced account.
- No hidden telemetry.
- No repository upload.
- Built for local agent workflows.

documentation
every feature, documented.
A landing page for each feature, plus the reference docs — what it does, why it matters, and how it works. No sign-up, nothing to install to read it.
start with the basicsfeatures
Grid
Launch up to 12 real PowerShell shells side by side, all rooted in one project.
Rigs
Save your whole terminal workspace as a named rig, then launch it in one click.
Pulse
See every terminal's pulse and jump straight to the agent that needs you.
Code Map
Scan your repo into a local symbol graph, then verify any symbol's blast radius.
Symbol Graph
Pick a symbol, see exactly what breaks if you rename it — offline.
Context Injection
Turn a task sentence into a budgeted, local-only context packet for your agents.
Config Advisor
Per-task model and effort picks, explained, with one-click apply — never silent.
Broadcast
Type a command once, fire it into every live pane at once.
Relay
Chain headless agents step by step, output flowing forward, pausing at every checkpoint.
Worktrees
PARTIALSee every git worktree as an agent-aware swimlane, live and fully local.
Workspaces
Run many projects at once. Switch instantly. Nothing in the background ever stops.
Rig Resume
Local checkpoints that bring your whole grid back. Resume the rig, not the chaos.
Run Logging
Bracket any terminal, capture its raw ANSI output, replay it later — all on disk.
Auto-Update
PARTIALSigned, silent self-updates that respect your bandwidth and never phone home.
Run 13x free — fully local.
Map your codebase, split a prompt across a rig, and run every terminal and agent from one workspace. Pay once for Lifetime and it’s yours forever.
