dendrobundle vs Bundlewatch
Bundlewatch is a well-maintained open-source CLI tool that checks your built asset sizes against configured thresholds and posts a pass/fail status to GitHub pull requests. It is the right choice if you want a simple, auditable, self-hosted gate with no SaaS dependency. dendrobundle is a hosted service that goes further: it records every snapshot, renders an interactive module treemap, sends email regression alerts, and gives you a rolling history chart across commits and branches.
dendrobundle vs Bundlewatch, feature by feature
| feature | dendrobundle | Bundlewatch |
|---|---|---|
| Build-fail budgets (block PR on size threshold) | Yes — per-project budgets that fail CI | Yes — core feature; thresholds per file pattern |
| Per-commit history and trend charts | Yes — every push recorded; history per branch | Unverified — service stores data, history scope undocumented (verify) |
| Interactive module-level treemap | Yes — drill from total into individual modules | No |
| PR comment with size diff | No (in development) | Yes — GitHub status check; PR comment via a separate action |
| Email regression alerts | Yes (Developer tier) | No |
| Weekly/monthly digest emails | Yes (Developer tier) | No |
| README SVG size badge | Yes | No |
| Accepts existing stats files without a plugin | Yes — webpack/esbuild/rollup-visualizer/source-map-explorer | Yes — operates on built file paths |
| Self-host option | No | Yes — run your own instance |
| Open source | No | Yes (MIT) |
| Free tier | Yes — 3 projects, 10 rolling snapshots, no card | Yes — tool and hosted service are free |

Bundlewatch vs dendrobundle — FAQ
- Should I use Bundlewatch or dendrobundle?
- If you want a fully self-hosted, auditable OSS tool that simply gates PRs on file size — with no need for history charts, treemap drill-down, or email notifications — Bundlewatch is a solid, zero-cost choice. If you want to track how your bundle evolved across dozens of commits, get emailed when a specific chunk grows past its budget, or hand a non-engineer a visual treemap, dendrobundle does that without you building the infrastructure.
- Can I migrate from Bundlewatch to dendrobundle?
- Yes. The webpack stats, esbuild metafile, or other bundler artifact you already produce is the input dendrobundle reads. Replace the Bundlewatch CI step with a single curl to the push endpoint, or drop in the GitHub Action. Historical Bundlewatch data cannot be imported, so you start fresh from the point of migration.
- When is Bundlewatch the better choice?
- Bundlewatch is the better choice when your team requires an open-source, self-hostable tool with no external data dependency, when you are building a library with strict package size constraints, or when your organisation's data policy prohibits sending build artifacts to a third-party SaaS.
