Hydrate vs Supermemory
agent memory infraFast commercial 'Memory API for the AI era' with /context plugins for Claude Code/OpenCode — most coding-fit of the memory-API tools, but per-user infra, not team canon or cross-vendor live coding memory.
What Supermemory is
| Stack / runtime | Memory + context engine; can run fully locally; MCP server + plugins |
| Licence | Commercial (generous free tier: 1M tokens / 10K queries) |
| Storage | Memory/context engine (local-capable) |
| Hooks | Plugin + /context command |
| Injection | /context command + MCP |
| Scope | General memory API; coding plugins for Claude Code + OpenCode |
| Maturity | Commercial; also publishes supermemoryai/memorybench |
| Price | Free tier + paid (all.astro cites $0/$19/$399/custom; verify) |
| Version referenced | 2026 |
| Source | github.com/supermemoryai/supermemory |
Where Supermemory leads
- Most coding-agent-fit memory API (/context plugins for Claude Code + OpenCode)
- Fast retrieval (~70ms p50 claimed) + top-leaderboard claims
- Contradiction resolution + selective forgetting as first-class API features
Where Hydrate leads
- Team canon propagation with attribution (per-user store in Supermemory)
- Cross-vendor live coding sessions
- Automatic, zero-cost, decision-centric capture
- Orchestration + three-layer bootstrap; single dependency-free binary

Verification notes
Benchmark claims are SELF-REPORTED and not independently verified (doc cited ~75% LoCoMo; other sources cite ~94.5% recall@10 — unstable). Never republish as fact. Verify paid tiers vs all.astro.
