Automated Job Queue Balancing

Problem Context

Teams use GitLab for CI/CD but hit a bottleneck: their test runners can’t handle parallel jobs efficiently. Heavy memory tests (like Playwright) block lighter tasks, causing delays. Users waste time setting up complex workarounds instead of coding.

Pain Points

GitLab’s job groups only run one job at a time, even when machines are free. Users try messy fixes like over-provisioning runners or manual tags, but these add cost and complexity. Pipelines stall, releases delay, and devs spend hours tweaking configurations instead of shipping features.

Impact

Slow tests cost teams real money—every hour of downtime means lost revenue and frustrated customers. Devs burn out fixing pipelines instead of writing code. Small teams can’t afford to scale runners infinitely, so they’re stuck in a cycle of inefficiency.

Urgency

This isn’t a ‘nice-to-have’—it’s a blocker. Teams can’t ship reliably without fixing their CI/CD bottlenecks. The longer they wait, the more they fall behind competitors who’ve solved this problem.

Target Audience

Small-to-mid-sized tech teams using GitLab for CI/CD, especially those running memory-heavy tests (Playwright, Selenium, etc.). Freelancers and startups hit this hardest because they lack resources to over-provision runners.

Solution Approach

A lightweight plugin for GitLab that automatically balances job queues. It lets users tag jobs (e.g., heavy, light) and intelligently schedules them—prioritizing heavy tests while filling gaps with lighter ones. No runner changes or complex setups needed.

Key Features

1. Dynamic Scheduling: Heavy jobs get dedicated slots; lighter jobs fill idle runner time.
2. Zero Config: Works with existing GitLab runners—no new infrastructure.
3. Priority Rules: Deploy jobs jump the queue, and critical tests run first.

User Experience

Users add a simple label to their job (e.g., heavy). The plugin auto-schedules it, ensuring tests run faster without manual tweaks. Devs spend less time fixing pipelines and more time coding. Releases ship on time, and teams save hours weekly.

Differentiation

Unlike manual workarounds (which add cost and complexity), this plugin *automates- the scheduling logic inside GitLab. No other tool solves this natively—users either over-provision runners or accept slow pipelines. Our solution is the missing middle.

Scalability

Starts with basic scheduling, then adds features like historical analytics (e.g., ‘Your heavy jobs take 30% longer on Tuesdays’) and Slack alerts for blocked pipelines. Pricing scales with team size (per-runner or per-team plans).

Expected Impact

Teams ship faster, devs focus on coding, and pipelines run smoothly. The plugin pays for itself in hours saved—no more wasted time or over-provisioned runners. It’s the ‘set and forget’ fix for GitLab’s biggest bottleneck.
