More than a bot. Your whole dev loop, in Slack.

Beacon is an agentic teammate, not a Q&A box. From one Slack thread it deep-dives your codebase, reviews pull requests, triages failing builds, and opens the fix PR — taking real steps on its own, every answer and action grounded in your code.

Start onboarding See what it does

Far beyond Q&A. It reviews PRs, triages broken builds, digs through the codebase, and ships fixes — not just chat replies.

Agentic, not one-shot. Beacon plans, retrieves, reads further, and takes action across steps until the job is actually done.

Grounded in your code. Every answer and every action cites the exact files and lines behind it.

What it does

One teammate, across the whole loop.

  1. Ask

    It starts where your team works.

    Mention @beacon or run /ask-code in any channel, DM, or the Slack assistant pane.

  2. Investigate

    It deep-dives your codebase.

    Beacon searches by keyword and by meaning, follows calls and imports, and keeps reading until it has the full picture.

  3. Answer

    It replies with proof.

    Answers stream in with the exact file paths and line ranges, so anyone can check the source on the spot.

  4. Review

    It reviews pull requests.

    Paste a PR link or react to one, and Beacon reviews it against your whole codebase — not just the diff.

  5. Triage

    It diagnoses failing builds.

    Red GitHub Actions turn into cited diagnoses, with flaky tests separated from real breakage.

  6. Fix

    It opens the fix PR.

    Give the word, and Beacon writes the change and opens the pull request — ready for your team to review.

Why you can trust it

An answer you can't verify isn't an answer.

01 / Grounded

Cited or silent.

Beacon answers only from code it actually retrieved, and shows you the file and line behind every claim. If the evidence isn't there, it says so instead of filling the gap with confidence.

@beacon can the cache ever serve stale data?

Beacon APP

No — entries are invalidated on write in writeThrough(), so reads always hit fresh data.

cache/store.ts:54-72

02 / Thorough

It traces the why.

Keyword search, meaning-based search, and call-graph tracing work together — and Beacon reads further when the first pass comes up thin.

03 / In Slack

The thread is the workspace.

Channels, DMs, mentions, slash commands, and emoji reactions all keep the team's context — no new tool to learn.

@beacon what broke this build?

Beacon APP

hydrateContent() is the likely cause. React 🚀 to open the fix PR.

How it compares

Other tools do one slice. Beacon runs the loop.

Cursor Slack Agent

Answers questions near the editor.

Beacon is an agent, not a chat box: it investigates, answers, reviews PRs, triages failing builds, and opens fixes — from the team thread.

Beacon edge: acts across the whole loop, not one reply.

CodeRabbit-style Slack agent

Reviews the pull request.

Beacon reviews too — and also answers the question before the PR, deep-dives the codebase, and diagnoses the build that breaks after it merges.

Beacon edge: the whole SDLC, not a single stage.

Generic AI in Slack

Confident answers you can't check.

Beacon won't answer without retrieved evidence — and it actually does the work: reviewing, diagnosing, and opening PRs, not just talking.

Beacon edge: acts on your code, with proof.
The difference One agent across the whole loop — investigate, answer, review, triage, fix — every step cited.

Deploy it your way

Hosted by us, or isolated in your own cloud.

Run Beacon as a managed instance we host, or as a dedicated, isolated deployment in your own infrastructure — whichever your security needs call for. Either way, secrets are redacted before they're stored, your code stays scoped to your workspace, and the pipeline is yours to inspect.
