Introducing Ivy Tendril: Open Source Coding Orchestration

Today we're launching Ivy Tendril, open source coding orchestration for teams shipping production-ready code with AI.

The fastest way to build with AI just got faster.

From idea to pull request, in minutes. Point Tendril at an issue and watch it plan, code, test, and ship the PR. It gets smarter with every run.

Why we built it

The new competitive edge isn't writing code. It's managing agentic output at scale.

Agents are good at coding. Humans have ideas, experience, and taste. Our mission is to minimize the friction between the two, and Tendril is how we do it. It gives developers a harness to run agents the same way they run tests or deployments: structured, verified, and in the open.

What Tendril does

Tendril is the ultimate agentic workflow tool. Orchestrate agents, tasks, codebases, and GitHub repos in one place.

  • Agent-agnostic. Works with Claude Code, Cursor, Windsurf, and more. Keep the agents you already trust.
  • Built on Promptware. Self-improving software agents with specific tasks, knowledge, tools, and memory. Your workflows learn, adapt, and get better with every run.
  • Verification gates. Automated build, test, lint, and format checks must pass before any code advances. Failures feed back to the agent with full logs for iterative correction.
  • Isolated execution. All agent work happens in git worktrees, completely separated from your main branches until a human approves.
  • Persistent memory. Agents capture patterns, conventions, and lessons specific to your codebase. They get better over time.
  • Cost and token tracking. Live monitoring of token usage and estimated spend per task.

How it works

Ivy Tendril is built on Promptware. Each part of the development cycle is handled by a dedicated Promptware that runs a simple cycle:

  1. Load. The agent reads its evolving Program.md, the living source code.
  2. Remember. The agent draws on persistent memory and tools from previous runs.
  3. Execute. The agent performs the task with full context of everything it has learned.
  4. Evolve. The agent reflects on results and rewrites its own instructions.

That's why Tendril compounds in value. The longer you use it on a codebase, the more it knows about how you build.

Powered by the Ivy Framework

Tendril is powered by the Ivy open source framework. Fully customizable, enterprise ready. Open it in any code agent and make it yours.

Get started

Download the software, connect it to one or more GitHub repositories, and start working.

# macOS / Linux
curl -sSf https://raw.githubusercontent.com/Ivy-Interactive/Ivy-Tendril/main/src/install.sh | sh

# Windows
Invoke-RestMethod -Uri https://raw.githubusercontent.com/Ivy-Interactive/Ivy-Tendril/main/src/install.ps1 | Invoke-Expression

# .NET Tool
dotnet tool install --g Ivy.Tendril

Then run:

tendril

Full docs are at the Tendril installation guide.

Get involved

Tendril amplifies great developers, it doesn't replace them. We're building it in the open, and we'd love your help shaping it.

  • Star, fork, and contribute on the Ivy Interactive organisation on GitHub.
  • Chat with the community on our Discord.

Help us make Ivy Interactive, and your team, the fastest builders in their industry.
