Top 7 Phabricator alternatives for stacking workflows

While technically you could still maintain and host Phabricator yourself, potentially a viable option for open-source development environments on tight budgets, you should consider a Phabricator alternative to future-proof your development workflows. Let’s look at the seven best alternatives on the market in 2024. 

1. Graphite: For faster, stacked PR workflows

Graphite is one of the latest entrants to the dev tools space, bringing capabilities tuned specifically for fast iteration and collaborative development. It was built as a direct replacement for Phabricator and mirrors the functionality of the stacked diffs (or stacked PR) workflow initially made popular by Phabricator.

Graphite aims to optimize the inner dev loop, facilitating rapid review turnarounds and continuous integration. This, at present, is the closest alternative to Phabricator, enabling the same workflow features.

Features of Graphite

Better pull request management

• PR stacking: Graphite allows the automatic grouping of logically connected pull requests in sophisticated hierarchies called stacks. All interdependent changes are structured sequentially, allowing developers to break up large feature changes into small, atomic pull requests.   Stacking has been proven to streamline workflows and accelerate development. 

• Improved PR workflow: The PR inbox instantly highlights urgent reviews and stale PRs so you can focus attention where needed. Custom email notifications also filter only important PR updates to avoid inbox fatigue.

• Insights: You can view historical statistics and gain insights on PR acceptance rates, review turnaround times, and workload, helping optimize team collaboration efficiency over time.

Integration with existing tools

• GitHub integration: Graphite bi-directionally interfaces with GitHub—automatically syncing PR changes across both platforms. This maintains consistency between PR updates without tedious manual sync, enabling incremental adoption and cross-platform collaboration between Graphite and GitHub users

• VS code extension: The Graphite extension for Visual Studio Code provides tight integration for stacked PR management right within the editor. Developers can execute complex  Git commands visually, with the push of a button, and manage stacks/PRs without switching contexts.

User experience refinements

• Merge flexibility: For stack merges, Graphite automatically handles complex cascading rebases, taking the toil out of manually managing stacks of PRs.

• Visually intuitive: The UI improves upon familiar paradigms, keeping the code front and center while filtering out the noise.  This enables faster onboarding without the need to relearn complex concepts.

• Ongoing improvements: Graphite receives frequent updates, ensuring continual refinements based on user feedback. Recent additions include a new CLI and redesigned VS code extension.

Pros of Graphite

• Centralized, a diverse range of features like support for stacked pull requests, intelligent notifications, an advanced, filtered PR inbox, and a completely redesigned CLI that automates tedious complexity like squashing and rebasing. 

• The VS Code extension feels like a natural part of the editor UI rather than a separate bolt-on. Developers can execute and handle Git commands and create/manage stacks and PRs without leaving their flow.

• Graphite’s Insights dashboard tracks your team’s performance over time. Measuring your team’s response time, time to merge, and review cycles gives you granular data to help you identify and fix bottlenecks that slow everyone down.

Cons of Graphite

• Some engineers may be initially hesitant to adopt the stacking workflow. Adoption requires some time to acclimate, however, intuitive design accelerates onboarding.

• Only supports GitHub. Does not work on GitLab, bitbucket, or any other version control system.

Graphite is perfect for teams moving from the OG, Phabricator, and want a purpose-built platform for the stacking workflow. So, if you want the perfect Phabricator alternative, sign up for a free Graphite account and try the stacking workflow.

Gerrit offers some features that improve the quality of the code review process. But, the consensus among developers seems to be that it’s a tool aimed at improving top-down control versus a tool designed to make individual developers more effective or efficient. 

Key factors when comparing Phabricator alternatives

Choosing the right development platform is important for engineering effectiveness and software quality. Consider the following key factors when finding the right tool for your team:

Team size and project scale

The number of developers on a team determines how sophisticated a tool you need. A simple GitHub project board may be enough for a startup with five developers to track issues and code reviews.

However, a 50-person engineering team across multiple products needs systems and workflows that focus on improving individual productivity. They also need tools that simplify complex processes (like a dedicated pull request inbox). And they need insights into the team’s overall performance to quickly identify issues that could dramatically reduce overall throughput. 

Integration needs

Integrations determine how seamlessly your toolchain works together. If you use Jira for ticket tracking, Bitbucket connects code commits directly to Jira tickets without manual syncing between systems.

This prevents developers from constantly context-switching between apps, which hurts productivity. Similarly, Graphite can connect with your GitHub and Slack, allowing you to work between systems without switching contexts.

Ease of adoption

User experience factors like clean UI, intuitive navigation, helpful documentation, and quick ramp-up time determine adoption across diverse technical proficiency levels.

If only select highly skilled developers can navigate a complex platform interface and configuration, usage suffers. Tools like GitHub, focus extensively on refining interfaces and increasing simplicity for broader access.

Features

The breadth, depth, and quality of features determine how well a platform maps to specialized needs around code, collaboration, planning, or delivery while providing a consolidated hub for end-to-end visibility. 

Teams relying heavily on code review efficiency may want purpose-built tools like Graphite over more generalized platforms. Audit must-have workflows before expanding functionality.

Budget

Development platforms balance capabilities to cost across a spectrum of free, freemium, premium, and enterprise tiers. GitHub's free offering provides robust functionality for early-stage startups. 

As usage grows with more private repos and contributors, premium plans add advanced controls. Tools like Gitlab may help larger companies scale with robust security, compliance, and automation capabilities.

Why finding the right platform matters

Choosing ineffective tools hurts engineer productivity and software quality. The wrong solutions can frustrate developers, leading to disengagement.

Conversely, platforms aligning seamlessly to team practices unlock faster innovation, uphold quality, and boost collective accomplishments. Smooth technology elevates outcomes.
