DECISION GUIDE
When to pick each, and when to skip both.
Three plain-English paths: the case for Hazelcast, the case for Apache Ignite, and the free bring-your-own-key route that avoids seat fees entirely.
When to Pick Hazelcast
98.7 / 100- 6,620+ GitHub stars as the leading real-time stream processing and distributed in-memory compute platform
- Sub-millisecond latency combining fast state storage with event stream processing pipelines
- Cuts $3,100/mo commercial Redis Enterprise & Oracle Coherence bills down to $260/mo self-hosted (-91.6%)
When to Pick Apache Ignite
98.1 / 100- 5,080+ GitHub stars delivering a comprehensive distributed database and in-memory computing platform
- Full ANSI SQL-99 support with distributed joins, secondary indexes, and multi-partition ACID transactions
- Native persistence layer combines in-memory speeds with zero-data-loss durability and instant warm restarts
When to Skip Both (BYOK OSS)
Aider / Cline- $0/mo Seat Fee: Pay pure upstream Anthropic/DeepSeek/OpenAI API rates or run local Ollama models for $0.
- Zero IDE Lock-In: Keep standard VS Code, Neovim, or JetBrains with deterministic git commits.
- 45% Lower API Burn: Route simple edits to Haiku/DeepSeek and hard diffs to Sonnet/Opus via LiteLLM.
