Scira
AGPL-3.0Scira is an open-source alternative to Perplexity that queries live web sources, cites references inline, and lets developers choose their own AI models.

Overview
Scira started as MiniPerplx before rebranding around the Latin root for knowledge, assembling a Next.js and Vercel AI SDK stack that routes research queries across frontier models and search scrapers. The platform queries external engines like Exa and Firecrawl to return cited web answers using direct API keys instead of proprietary seat subscriptions. For developers investigating documentation or incident traces, it provides an open alternative to closed search portals.
Why Scira instead of Perplexity
Scira replicates the core mechanism popularized by Perplexity: real-time web retrieval paired with inline citations and multi-step reasoning. Where Scira changes developer workflows is inference control. Instead of relying on a locked search aggregator and monthly subscription tiers, engineers route queries to specific models—including Claude Sonnet, OpenAI o3, DeepSeek R1, and Grok—while delegating retrieval to engines like Exa for technical articles and Firecrawl for clean scraping. When debugging obscure compiler errors or researching unfamiliar libraries, this setup surfaces primary documentation rather than generic summaries.
The operational tradeoff centers on setup and hosting overhead. Perplexity provides a turnkey ecosystem with native mobile apps, unified billing, and managed persistence requiring zero configuration. Scira shifts those tasks to engineering teams: self-hosting via Docker requires PostgreSQL, Redis, and separate API accounts across multiple search and model vendors. While daily querying feels familiar across both tools, teams must weigh the flexibility of custom model routing against the maintenance of upstream API keys and token quotas.
What it does well
- Multi-provider routing: sends prompts to Claude Sonnet, OpenAI o3, DeepSeek R1, or Grok depending on code synthesis or latency needs.
- Targeted retrieval: queries Exa for technical documentation, Firecrawl for web scraping, and Supadata for video transcripts.
- Sandboxed execution: runs generated Python code in a Daytona sandbox, letting engineers verify scripts and view charts inline.
- Developer search modes: provides dedicated filters for GitHub repositories, documentation sources, Reddit discussions, and arXiv papers.
- Automated topic tracking: schedules Lookouts that monitor web endpoints or documentation changes and send email updates.
