Temporal AI and Perseus serve completely different needs: Temporal is for building reliable, long-running AI agents and workflows with automatic failure recovery, while Perseus is a code search engine that grounds coding agents in accurate context. If you need to orchestrate multi-step agentic workflows that survive crashes, choose Temporal. If you want your coding agent to retrieve precise, cited code snippets quickly, go with Perseus. They are complementary – you could even use both together.

Features
Cited codebase search returning exact file paths and line ranges to coding agents
Semantic code search that finds code by meaning rather than substring matching
Multi-hop search that follows a thread across more files in a single pass
Constrained search that narrows a query with additional conditions
Research packets combining 2-8 linked questions into one answer with a combined reading list
Impact analysis mapping the dependency surface before editing a shared symbol
Eval mode that turns the current diff into a verification plan with test commands
Path tracing between two symbols with configurable max depth
Diff search modes for changed, impacted, and regression queries
Incremental re-indexing of the working tree that uploads only changed files
perseus watch to sync edits in the background during active work
Indexing of local working trees and GitHub repositories by URL or owner/repo
CLI with --json output for piping ranked, cited hits into other tools
HTTP API returning ranked cited results to third-party tools and agent integrations
Agent skill install via npx skills add, plus perseus rules for repo-local agent rules
Durable execution captures Workflow state at every step with no checkpointing or recovery code
Native SDKs for Go, Java, Python, TypeScript, .NET, PHP, Ruby, and Rust
Activities retry automatically with backoff, four timeout classes, and heartbeating
Signals, Queries, and Updates read and mutate running Workflows mid-flight
Workflow Streams for real-time interactivity with running executions
Durable AI agents via OpenAI Agents SDK and Google ADK running LLM and tool calls as Activities
Standalone Activities as a durable job-queue pattern, GA across six SDKs (2026-09-15)
Serverless Workers for Google Cloud Run, public preview (2026-10-05)
Serverless Workers for AWS Bedrock AgentCore, pre-release (2026-09-18)
Native Task Queue priority and fair distribution without a custom queueing layer
Durable Timers that sleep for months; cron Schedules with backfill and Continue-As-New
Saga pattern via compensating transactions that read like try/catch
Worker Versioning pins Workflows to a version so deploys don't corrupt in-flight runs
Cloud UI Strict Session Mode: 15-minute inactivity timeout, 12-hour max session (GA)
Replay tests validate against real histories; time-skipping tests fast-forward long timers in CI
