How it works

A new way to build software

From a Slack message to production. Agents handle triage, specs, estimates and retrospectives, and people review and decide. No sprints, no story points, no standups.

The problem

Most of the week isn't code.

Specs, status updates, estimates and meetings fill the rest. That is the work Glideship hands to agents, so people keep the decisions and get the time back.

16%

is how much of their time developers spend coding, Atlassian reports. The rest of the week goes on everything around the code.

The flow

Nine phases. One BUD.

Every feature follows the same path. At each step an agent drafts the work and a person reviews it, changes it and moves it on.

Phase 1 of 9

A request comes in

Someone asks for something in Slack. The Triage Agent reads it, checks for duplicates and runs a short interview about business impact, who it is for, timing and dependencies.

What agents do

Reads the request, looks for duplicates, sizes the work from the code, and suggests a priority to the product manager.

What people do

Shares the idea and answers the questions. A product manager or the org owner reviews the triage, adjusts it and moves it on to a BUD.

Who does what

Agents do the process work. People decide.

An agent never ships on its own say-so. Each draft lands in front of a person, who can approve it, change it or send it back.

Agents handle

  • Sorting new requests and spotting duplicates
  • Drafting BUDs from your real code
  • Scoping design work and writing the tech plan
  • Writing test cases, automated and manual
  • Linking bugs to BUDs and watching bug counts
  • Tracking status and keeping stakeholders posted
  • Spotting patterns and writing retrospectives
  • Mapping skills and suggesting who takes what
  • Keeping knowledge in sync with the code
  • Delivery dates with real odds (AI-PERT + Monte Carlo)

People handle

  • Reviewing and approving every phase
  • Code review and architecture choices
  • Visual design, in the tools they like
  • Business trade-offs and priorities
  • Quality checks and UAT sign-off
  • Reviewing or overriding reassignments
  • Curating knowledge and team rules
Why people stay in charge
46%

of developers distrust the accuracy of AI tools, more than the 33% who trust it. Only 3% highly trust the output.

Frequently asked

Questions, answered.

What is Agent-Driven Development?

Agent-Driven Development (ADD) is a way of building software where specialised AI agents drive every phase of the lifecycle — intake, spec, design, tech architecture, implementation, testing, UAT, deployment, retrospective — and humans review, decide, and steer. Glideship is the open-source reference implementation.

Is Glideship a self-hosted Jira alternative?

Yes — for the workflow layer. Glideship sits between IDE-side AI coding assistants and traditional PM tools. It is especially relevant to teams looking for an Atlassian DC alternative, since Atlassian is sunsetting new self-hosted Jira licences in March 2026 with full shutdown in 2029.

Does my code leave my machine when I use Glideship?

The data plane is always local — Postgres, embeddings, BUDs, scanned repos, and the audit log all sit on your hardware. Only the LLM prompts leave your machine, and only when you choose a cloud inference mode.

What does BUD mean in Glideship?

BUD stands for Business Understanding Document. Every feature lives in one BUD containing spec, tech spec, test plan, acceptance criteria, and full history — all in markdown.

What is Glideship's licence? Can I use it commercially?

Glideship is licensed under the Apache License 2.0, which permits commercial use including embedding in proprietary products. Contributions require DCO sign-off via git commit -s.
