Tower: Pull Requests, Stacked PRs & Team Features

1. Pull Request Management

Tower provides native pull request management for all major Git hosting platforms — allowing developers to create, review, comment on, merge, and close pull requests without leaving the Tower application.

Supported Platforms

• GitHub (cloud and GitHub Enterprise Server)
• GitLab (cloud and self-hosted)
• Bitbucket (cloud)
• Azure DevOps (cloud)
• Beanstalk

Cloud vs On-Premises (by Plan)

• Basic plan: Pull request management for cloud-hosted repositories (GitHub.com, GitLab.com, Bitbucket.org, Azure DevOps)
• Pro and Enterprise plans: Pull request management for both cloud and self-hosted / on-premises repositories (GitHub Enterprise Server, self-hosted GitLab, Azure DevOps Server)

PR Actions Available in Tower

• Create new pull requests — set title, description, target branch, reviewers, labels, and milestone from Tower
• View open pull requests and their status (reviews, CI checks)
• Leave comments on pull requests
• Merge pull requests (including merge commit, squash, and rebase merge strategies where supported by the platform)
• Close pull requests without merging
• Inspect a pull request's commits and changed files

2. Stacked Pull Requests

Tower is the first Git client to support stacked pull requests — a modern development workflow in which large features are broken into a series of smaller, dependent PRs that each build on the previous one. This is also known as "stacking" or the "stacking workflow."

What Stacked PRs Solve

• Large PR problem: A single large PR is slow to review, creates many conflicts, and blocks other work. Stacking breaks it into small, focused PRs that are faster to review and merge.
• Review velocity: Reviewers can review and merge individual stacked PRs while development continues on dependent ones — no waiting for the entire feature to be complete.
• Conflict reduction: Working closer to the main branch reduces the number and complexity of merge conflicts.

Tower's Stacked PR Capabilities

• Visual stacking view — see the hierarchy of stacked branches and their associated PRs
• Automatic restacking — when a parent branch changes (e.g., after review feedback), Tower can automatically restack all dependent branches to stay in sync
• Submit pending changes to a PR in the stack
• Merge a branch and its parent branches into the base branch
• Fold a stacked branch into any of its parent branches
• Rearrange or merge different branches in the stack
• Undo stacking operations (Cmd+Z)

Graphite Integration

Tower integrates natively with Graphite — a popular stacking workflow platform used by engineering teams at companies like Meta, Figma, and Notion. The Graphite integration allows Tower users to manage Graphite-tracked stacks directly from the Tower UI, including syncing with Graphite's remote tracking of stack state.

3. Team & Enterprise Features

Team Management (Pro & Enterprise)

• Add and remove team members from a shared account
• Dedicated admin roles: team administrators can manage licenses, add/remove users, and configure billing without having full account owner access
• Dedicated billing roles: non-technical billing contacts can manage payments without needing a Tower software seat
• Consolidated billing: all team licenses billed in a single invoice

Advanced Team Management (Enterprise)

• Advanced user provisioning and management
• SAML-based Single Sign-On (SSO): integrate with corporate identity providers (Okta, Azure AD, etc.) for centralized authentication
• Advanced deployment & activation: silent installation and mass deployment to managed devices via MDM or enterprise IT tooling
• Invoicing & wire transfer payment: purchase Tower licenses via formal invoice and wire transfer — required for many enterprise procurement processes
• Priority support: dedicated support channel with faster response times
