# Pollen WASM runtime

10 Hacker News commenters recommended Pollen WASM runtime and 0 criticized it, November 2025 to November 2026. It was recommended in 1 of 13 months.

**Verdict:** Single-binary WASM runtime with no control plane; the cluster balances compute on its own. Caveat: unclear which WASM feature sets are supported.

## Why people recommend it

- Cluster balances compute automatically (2 comments): "because you'd get a natural balancing of compute; heavy functions scale more aggressively, light functions less so." ([source](https://news.ycombinator.com/item?id=48047603)) "let the cluster organically balance the compute as the different usage patterns occur" ([source](https://news.ycombinator.com/item?id=47993954))
- Leaderless design with gossip-based scaling (2 comments): "Really neat project. The idea of a fully decentralized leaderless WASM runtime is bold." ([source](https://news.ycombinator.com/item?id=47988971)) "Using CRDT gossip to inform scaling is a clever idea." ([source](https://news.ycombinator.com/item?id=47986505))

## What people warn about

- Unclear which WASM features are supported (1 comments): "This looks fantastic, however it's not clear (to me), which WASM feature sets are supported?" ([source](https://news.ycombinator.com/item?id=47998907))
