Sigilix

Overview

Sigilix is an AI development platform that handles code review, CI failure triage, and issue triage from a single org-aware system. It installs as a hosted GitHub App with no workflow YAML or self-hosted runners required. Every finding includes a suggested fix and citations, verified through provenance and live execution gates. Review, CLI, Slack, and chat all share one memory index scoped to your org and each developer, so context gathered in one surface is available in the others.

Key Features

Automated PR Reviews: Install the GitHub App and reviews fire on every pull request. No workflow files, runners, or Docker images needed since compute runs on Sigilix infrastructure.
CI Failure Triage: Turns red builds into grounded, inline root-cause comments instead of raw log dumps. Findings land in your existing PR and issue rail.
Linear Issue Triage: Integrates with Linear to triage tickets using the same memory index that powers code reviews.
Shared Memory Index: Review, CI triage, CLI, Slack, and chat all read from one persistent memory scoped per org and per developer, so context carries between surfaces.
Model Routing: Routes work across three tuned models (Boreas, Pyroeis, Astraeus) based on task difficulty, keeping routine reviews cheap while reserving deeper reasoning for hard changes.
Verification Gates: Every finding must pass provenance, self-refutation, and live execution checks before posting, each carrying a proof tier (VERIFIED, GROUNDED, or MODEL).
Suggested Fixes: Every finding ships with a ready-to-apply fix plus a one-click "Prompt to Fix with AI" you can hand to your coding agent.
CLI with BYOK: The Sigilix CLI supports bringing your own provider key on any paid tier, while defaulting to Sigilix models.

Pros

No Setup Overhead: Install the GitHub App, grant repo access, and reviews run. No YAML, runners, or CI changes required.
Context Carries Across Tools: A review comment knows the issue that motivated it, and a CLI repair knows the failing check, thanks to the shared memory index.
Unlimited Repositories on Paid tiers: Pro and higher paid plans include unlimited repositories, which suits teams managing multiple services or projects.
Verified Findings: Verification pills show which findings are backed by live execution versus model reasoning, so you can trust high-signal comments.
Cost-Efficient Routing: Routine review work uses cheaper models while harder changes get deeper reasoning, stretching your usage window.

Cons

BYOK Restricted to CLI: You can only bring your own provider key for the CLI. PR reviews, triage, Slack, and chat run on Sigilix models with no option to swap.
Usage Windows Can Pause Work: When included usage is spent, capped pools pause until the 5-day reset. There are no automatic overages on lower tiers.
GitHub-Centric: The platform is built around GitHub and Linear. Teams on GitLab, Bitbucket, or Jira have less direct fit.

Use Cases

Automated PR Review for Growing Teams: Install Sigilix on your GitHub org so every pull request gets an inline review with cited evidence and suggested fixes. Useful when human review bandwidth can't keep up with AI-generated PR volume.
Root-Cause Analysis of CI Failures: Instead of engineers digging through raw log dumps, Sigilix posts a grounded root-cause comment on failed builds. Cuts triage time for flaky tests and build breaks.
Linear Ticket Triage: Connect Linear so incoming issues get categorized, enriched, and cross-referenced with related code paths. Reduces the back-and-forth of clarifying tickets before assigning them.
Contextual CLI Coding: Use the Sigilix CLI locally with BYOK to make changes that know about your open PRs, failing checks, and past review decisions. Handy for engineers switching between repos.
Slack-Based Engineering Q&A: Ask the Slack assistant about a repo, a past review, or a recent incident and get answers grounded in the same memory index your review bot uses.
Cross-Repo Deep Research: Use Deep-Research Chat in the browser to trace how a change in one service affects another, backed by evidence from your org's code and tickets.

Frequently Asked Questions

How does Sigilix install and connect to my repos?

Sigilix is a hosted GitHub App. You install it, grant repo access, and reviews start firing automatically on every pull request. You don't need workflow files, self-hosted runners, or Docker images since all compute runs on Sigilix infrastructure.

Can I use my own API keys?

Yes, but only for the Sigilix CLI. BYOK is optional on every paid tier. PR reviews, CI triage, Slack, and Deep-Research Chat run on Sigilix's own model line with no BYOK option.

What are Boreas, Pyroeis, and Astraeus?

They are Sigilix's own model routes. Boreas is designed for fast, routine code work, Pyroeis handles everyday engineering tasks, and Astraeus is used for deeper repository-scale reasoning and harder engineering problems. Sigilix routes work based on the level of reasoning required.

How is Sigilix different from Greptile or CodeRabbit?

Sigilix is not limited to PR review. Its platform combines GitHub code review, CI failure triage, Linear issue triage, a CLI coding agent, Slack assistance, and research-based chat. These surfaces share workspace memory, allowing context from issues, reviews, repository history, and engineering decisions to carry into later work.

Does Sigilix work with GitLab or Bitbucket?

Sigilix's main pull request review workflow is built around GitHub. Its broader platform also includes Linear issue triage, Slack, CLI workflows, and browser-based research questions. Teams whose primary development workflow is based on another code hosting platform should confirm integration support before choosing Sigilix.
