dendrobundle vs RelativeCI
RelativeCI is a mature, job-metered SaaS that provides deep per-build bundle analysis with strong GitHub and Slack integrations, and it added treemap visualisation in 2024. Its free tier caps at 100 jobs per month, after which plans start at $29/month and scale with build volume. dendrobundle charges a flat $20/month for unlimited snapshots on the Developer tier — no per-job metering — which makes costs predictable for teams that run CI frequently.

RelativeCI vs dendrobundle — FAQ
- Should I use RelativeCI or dendrobundle?
- RelativeCI is the stronger choice if your team already uses Slack for CI notifications, needs GitHub Check reports rather than email alerts, or is running a high-profile open-source project (its OSS tier is always free). dendrobundle suits teams that want email-based regression alerts and digests, a predictable flat monthly cost regardless of build frequency, and a simpler push path that works with stats files your bundler already emits.
- Can I migrate from RelativeCI to dendrobundle?
- Partly. dendrobundle reads the same webpack stats and rollup-plugin-visualizer output that RelativeCI agents consume; you replace the agent with a curl command or the GitHub Action. Historical RelativeCI data cannot be imported, so if your team relies on long-term trend comparisons, factor in starting fresh.
- When is RelativeCI the better choice?
- RelativeCI is the better choice when your primary notification channel is Slack, when you want to forward metrics to an InfluxDB/Grafana stack, when you need a GitHub App with native Check report formatting, or when you are on an open-source project that qualifies for its always-free tier.
