Exabase is the data layer for AI agents. It gives your agents persistent memory, cloud storage, and semantic search so they can remember users, store files, and retrieve context across sessions.

The Memory API is a self-organizing memory system that stores facts, preferences, and events, then builds a living knowledge graph that tracks relationships, resolves contradictions, and evolves with every interaction. It's not a vector database. It's real, self-improving memory.

The Resources API provides a cloud-native filesystem for agents and users. Store files, notes, bookmarks, and documents with full CRUD, folders, tags, and semantic search built in.

The Bases API lets you create isolated cloud workspace instances on demand. Each one comes with its own memory, files, and search, fully controlled by your app and auditable through the API or web console.

Stop building memory infrastructure from scratch. Give your agents a place to work.

Analysis of grappa

Overall verdict

Grappa is a solid, mature parsing library for the JVM that lets developers build parsers directly in Java using a fluent, PEG-based (Parsing Expression Grammar) approach without needing a separate grammar file or code generation step.

Why this product is good

Uses Parsing Expression Grammars (PEG), which are unambiguous and easier to reason about than traditional context-free grammars
Grammars are written in pure Java as a fluent DSL, so there's no external grammar file or code-generation build step
Integrates naturally into existing Java/JVM projects and tooling
Supports parser actions, error recovery, and value stack manipulation for building ASTs
Successor to the popular Parboiled library, benefiting from lessons learned in that project
Open source and hostable/inspectable directly on GitHub

Recommended for

Java and JVM developers who want to build parsers without learning a separate grammar language
Projects needing custom domain-specific languages (DSLs) or configuration formats
Developers who prefer PEG semantics over ambiguous CFG-based tools like ANTLR
Teams that want parser logic kept inline in their codebase rather than generated
Prototyping and small-to-medium parsing tasks where fluent Java code is convenient

Analysis of Exabase

Overall verdict

Exabase appears to be a niche cloud/database platform, but based on limited publicly available information, it's difficult to fully verify its reliability, feature set, and long-term stability compared to more established competitors. Prospective users should conduct thorough due diligence, review current documentation, and test with a trial before committing.

Why this product is good

May offer competitive pricing or specialized features for specific use cases
Could provide a simpler alternative to more complex enterprise platforms
Potentially useful for developers seeking niche or specialized database/cloud solutions

Recommended for

Developers exploring alternative or niche cloud/database providers
Small teams or startups looking for cost-effective solutions
Users willing to test and evaluate newer platforms before full commitment
Technical users who can independently verify security, uptime, and support quality
