Coding-agent memory

21 systems in the coding-agent memory category of the AI Agent Infrastructure Landscape, grouped by maturity tier.

Tier 1 — battle-tested (5)

  • Augment Code Real-time semantic Context Engine + curated Agent Memory

    Real-time knowledge graph indexed from connected repos + commit history + CI/CD + tickets + docs. Separate Agent Memory layer (Sept 2025) captures session decisions/corrections/goals as discrete items with developer review/approval UI. M…

  • Devin (Cognition) Server-side Knowledge + auto-Repo Knowledge

    Structured Knowledge items stored server-side. Three-tier scope: repo-pinned (always injected), global (recall by relevance), org/enterprise (visible to org members). Auto-generates Repo Knowledge from repo structure each session; reads …

  • Mistral Vibe (Remote Agents) + Mistral Medium 3.5 Cloud-hosted async coding agents with teleportable session state

    Vibe is Mistral's cloud-hosted coding-agent platform: each session runs in an isolated sandbox with task state, history, and approvals. Spawnable from CLI or Le Chat, with parallel execution. Local CLI sessions can be "teleported" to the…

  • OpenAI Codex (cloud agent) File-backed ~/.codex/memories + Chronicle

    Memory under ~/.codex/memories/ : summaries, durable entries, recent-input logs, supporting evidence — generated in background after sessions go idle. Chronicle (opt-in macOS preview) uses screen-capture to seed memory. Off by default; o…

  • Replit Agent Project-files-as-memory + Temporal orchestration

    No documented built-in persistent semantic memory store. Session duration expanded to 200 min (Agent 3); Agent 4 shifts toward persistent runtimes. Temporal used for orchestration durability, not semantic memory. Cross-session memory rel…

Tier 2 — production-ready (6)

  • Aider Per-repo chat history file + YAML config

    Appends conversation turns to .aider.chat.history.md in project root. restore_chat_history defaults to false — no automatic replay into new sessions. Community /session save command for JSON state snapshots. .aider.conf.yml carries stati…

  • Bolt.new (StackBlitz) WebContainer file system

    In-browser WebContainer (Rust-backed shared memory) is the implicit state store. No dedicated memory abstraction — project files are the state. Team plan adds shared workspaces + GitHub integration.

  • Continue.dev Memory MCP KG-backed memory via MCP

    Discontinued: Continue was bought by Cursor (announced ~2026-06-16); the product is discontinued and the continuedev/continue repo is read-only. Official Memory MCP (Mar 2025) backed by a knowledge graph. Memory is injected via MCP rathe…

  • Lovable /docs folder + Knowledge Panel

    Long-term context stored as files in /docs that the agent reads on each session. Agent Mode (default since July 2025) holds working context within session but doesn't persist cross-session beyond filesystem state.

  • Sweep AI GitHub-thread-as-implicit-memory

    Superseded: the sweepai/sweep README says the team now builds an AI coding assistant for JetBrains; the GitHub-app product described here is no longer the focus (repo not archived). No dedicated persistent memory layer. Operates as a Git…

  • Tabnine Org-level Context Engine + Tabnine Agents

    Enterprise Context Engine builds a multi-dimensional knowledge graph from repos + CI/CD + PRs + tickets + docs at the org level. Individual completions stay session-scoped. Tabnine Agents (Nov 2025) adds team-shared agent context. Acquir…

Tier 3 — emerging (10)

  • agentmemory (rohitg00) Framework

    Self-hosted persistent memory layer that captures coding-agent activity and recalls it in later sessions, positioned on public benchmark results. #7 in TeleAI Awesome-Agent-Memory

  • Beads (Steve Yegge) Framework

    Dolt-backed, dependency-aware graph issue tracker that acts as persistent structured memory for coding agents, replacing markdown plans; `bd remember` stores durable facts and `bd prime` re-injects them.

  • context-mode Framework

    MCP server + hooks that sandbox tool output out of the coding agent's context window (claims ~98% reduction) and persist session memory across 17 agent platforms.

  • Cursor Memories Product

    Project-scoped memories in Cursor, created either by a background 'sidecar' model watching chats or by the agent via tool calls, and managed as auto-generated rules in settings. Traction: First-party feature of one of the most widely use…

  • Gemini CLI memory (save_memory / GEMINI.md) Product

    Google's open-source Gemini CLI persists facts by editing tiered Markdown memory files — repo GEMINI.md, a per-project private memory folder and global ~/.gemini/GEMINI.md — that load into hierarchical context each session. Traction: Goo…

  • GitHub Copilot Memory (agentic memory) Product

    Repository-scoped memories that Copilot coding agent, code review and CLI write automatically, share across features, validate against the current code before use, and expire after 28 days; owners can review/delete them. Traction: Shippe…

  • Letta Code Framework

    Letta's stateful coding-agent harness: agents rewrite their own memory blocks and skills, version context in git via MemFS (syncable to GitHub) and reflect via a periodic /sleeptime 'dreaming' process. from Letta (MemGPT) team. letta-ai/…

  • memsearch (Zilliz) Framework

    Zilliz's persistent memory layer shared across agents like Claude Code and Codex: Markdown files are the source of truth, and Milvus indexes them for search. from the Milvus vendor

  • OpenAI Codex Memories + Chronicle Product

    Codex Memories carries preferences, conventions and pitfalls across Codex threads as local memory files. The Chronicle research preview has been replaced by Computer History, a rebuilt macOS desktop feature (ChatGPT Pro, Business, Enterp…

  • Serena (Oraios) Framework

    LSP-backed MCP coding toolkit ('IDE for your agent') with a built-in project memory system for sharing knowledge across sessions, users and projects alongside AGENTS.md.
