Greplica
Queryable persistent repository memory for AI coding agents, reusing past experience and lessons before exploration.
About Greplica
Greplica is a persistent engineering memory tool for AI coding agents. It explores repository structure, code, and session records, distilling durable insights from past sessions into queryable memory: team decisions, discovered constraints, workflow files, pitfalls, and failed approaches, so the next agent can reuse this history before exploring. Local mode runs entirely locally with no telemetry; hosted mode connects authorized repositories to shared team memory, allowing contributors on different clones and forks to query the same memory while managing access through roles. Officially showcased planning cases reduced token usage by 40-50%; the best measured result used 75.0% fewer tokens and was about 38% faster. The tool is open source under the MIT license.
Best for
Best use cases
Query repository memory before agent planning to reduce repeated exploration and token usage
Help a new agent quickly learn repository decisions, constraints, and common pitfalls
Share the same repository memory across multiple clones and forks
Maintain coding-agent session memory in a fully local environment with no telemetry
Features
Persistent repository memory
Explores repository structure, code, and session records, distilling decisions, constraints, pitfalls, and failed approaches for agents to query before exploration.
Local and hosted modes
Local mode runs entirely locally with no telemetry; hosted mode connects authorized repositories to shared team memory and supports role-based access management.
One-click multi-agent connection
Connects Codex, Claude, Copilot, Cursor, OpenCode, OpenHands, Factory Droid, and Antigravity through one installation command.
Configurable embeddings and automation
Choose local or OpenAI embeddings during installation, and enable or disable hooks and automatic memory.
