append-only-log

A generic-purpose, atomic, ordered, zero-copy read, zero-cost (in-place) write, Write-Ahead Log implementation for Rust.

Document database with no database server. Tiny, LLM-friendly TypeScript API; DB engine runs to completion in each JS request handler; state lives in S3/R2.

A local-first agent memory lifecycle engine: typed memories in an append-only, integrity-chained log with dedupe, conflict detection, forgetting, compaction, verification, query, and portable export.

Agents you can inspect, replay and trust. An agent framework for TypeScript and Python, built on an append-only event log.

PostgreSQL-backed execution coordination primitive for correctness-sensitive distributed work.

Append-only log library for Go, backed by Amazon S3, Google Cloud Storage, or Azure Blob Storage. Replay by LSN or timestamp. No broker to run.

Rust CLI for reversible file operations. Every delete, modify, and move carries inversion metadata, enabling instant rollback without external backups. Uses content-addressed storage (SHA-256) and an append-only operation log. Formal proofs of the complete reversibility guarantee are pending.

Sync-first event sourcing for Rust: append-only segments, causal metadata, policy gates, and typed projections — no async runtime. It's free batteries bro, take 'em!

Head hashes of the SocialGravity identity ledger, mirrored hourly where we cannot quietly rewrite them. A public witness against our own future selves.

MIME-OS / EMLBox — single-file .eml container OS stack in Rust: mmap reader, hash-chained append-only delta log, KV, IPC bus, logic runner, tag-DB, multi-writer sync. Everything is .eml.

Distributed message queue combining Kafka's durability + SQS's simplicity + features neither has

Disk-backed message queue for single-process Go applications. Zero dependencies, with priorities, DLQ, compression and deduplication.

High-performance, zero-allocation general purpose write-ahead log (WAL).

Track Torah learning daf by daf, on an append-only event log — every count, streak and projection is a fold over it. Flutter, for Android, Windows, and a non-touch Sonim keypad phone.

Normalises market data from CSV, PCAP and live chart APIs into a canonical append-only event log, then replays it deterministically over a gRPC stream.

A private, crash-safe message and knowledge mesh for AI agents — signed append-only log, offline hybrid search, ranked budget-capped digests. Local-first, no cloud.

File-based credential vault: SHA-256 email IDs, bcrypt-salted passwords, each record Fernet-encrypted and appended to one log + tiny index for O(1) look-ups. No database, two files, scales to millions of users; ideal for secure prototypes, IoT, and web apps.

Turn Kafka records into durable, replayable histories—one per key, stored in your object storage.
