FasterGH Review (2026): Pricing, Features & Honest Verdict

TLDR

FasterGH is an open-source GitHub mirror that makes browsing repositories dramatically faster by caching data through Convex. Built by a Vercel engineer, it supports read and write operations without hitting the GitHub API on page load. Best for: developers frustrated with GitHub’s speed. Price: Free (open source). Rating: 7.8/10

What is FasterGH?

We spotted FasterGH on Product Hunt where it racked up over 1,300 upvotes, an impressive number for a developer tool. The creator, Rhys Sullivan (software engineer at Vercel), built it to solve a problem every developer knows: GitHub is slow. Pages take seconds to load. Navigating between issues, pull requests, and code feels sluggish, especially on large repositories.

FasterGH is an open-source GitHub mirror UI that uses Convex as a real-time caching and synchronization layer. GitHub remains the source of truth, but FasterGH serves a low-latency read model so the interface never hits the GitHub API on page load. It also supports write operations like creating issues, posting comments, and merging pull requests through optimistic mutations.

The data flow is clean: GitHub Webhooks and API feed into Convex ingestion, which normalizes tables into projection views that the Next.js UI renders. The result is a GitHub browsing experience that feels instant.

Key Features

Real-Time Sync via Webhooks

FasterGH streams GitHub webhook events into Convex for instant updates. When someone opens a PR or comments on an issue, the change appears immediately in FasterGH. There is no polling, no stale data, no manual refresh needed. This is fundamentally different from static caching approaches that serve outdated information.

Pre-Computed Projection Views

The real speed comes from denormalized views optimized for common GitHub workflows: repository overview, PR lists, issue lists, and activity feeds. These views are pre-computed and served without any GitHub API calls. The difference is noticeable, especially on repositories with thousands of issues or complex PR histories where GitHub itself can take 3-5 seconds per page.

Full Write Support

This is not read-only. You can create issues, post comments, and merge pull requests directly from FasterGH. Write operations use optimistic mutations, meaning the UI updates instantly and syncs to GitHub in the background. This makes the entire workflow feel native rather than like a secondary tool.

Multi-Strategy Data Synchronization

FasterGH uses four synchronization strategies: bootstrap backfill for initial repository hydration, real-time webhooks for ongoing updates, periodic reconciliation for drift repair, and async queued processing with retry and backoff. This layered approach ensures data consistency without sacrificing speed.

Pricing

FasterGH is free and open-source under the FSL-1.1-MIT license (Functional Source License with MIT future license). There are no paid tiers. Self-hosting requires a Convex account and a GitHub Personal Access Token with repo scope. The tech stack includes Next.js (App Router), Convex, Effect (functional TypeScript), Tailwind CSS, and Radix UI.

Who Should Use FasterGH?

FasterGH is built for developers and engineering teams who spend significant time browsing GitHub and find the native experience too slow. If you work with large repositories where GitHub’s interface feels sluggish, or if you context-switch between many repos throughout the day, the speed improvement is meaningful.

This is a developer tool through and through. Setup requires Bun 1.0 or later, a Convex account, and a GitHub PAT. It is not for non-technical users or teams looking for a managed service. If you want something that just works out of the box, the browser extensions (Gitako, Refined GitHub) are simpler options.

Alternatives

Refined GitHub

A browser extension that enhances GitHub’s native UI with hundreds of small improvements: collapsible sections, enhanced diffs, faster navigation, and cleaner layouts. Refined GitHub does not replace the GitHub interface but layers improvements on top. It is easier to set up than FasterGH (just install the extension) but cannot match the raw speed of pre-computed views.

Gitako

A browser extension that adds a file tree sidebar to GitHub, making code navigation much faster. Gitako is laser-focused on repository browsing rather than issues and PRs. If your main frustration is navigating code, Gitako solves that specific problem without the full infrastructure of FasterGH.

GitHub Desktop

GitHub’s official desktop client provides faster local workflows for common Git operations. It handles cloning, branching, committing, and PR management. However, it does not address the web browsing experience for issues, PRs, and repository exploration where FasterGH excels.

Verdict

FasterGH is an impressive technical achievement that proves GitHub’s web interface does not need to be slow. The architecture is thoughtful, the sync strategies are robust, and the result is a browsing experience that feels like it should be the default. The open-source nature and Vercel engineer pedigree add credibility. The main limitation is accessibility: self-hosting requires real technical setup, and there is no managed hosted version yet. If Rhys ships a hosted offering, this could become essential infrastructure for development teams. For now, it is a fantastic option for technically inclined developers willing to invest 30 minutes in setup for a permanently faster GitHub experience.
