Decision snapshot

Is this worth validating?

Build this if

You ship to indie devs and small teams who already run CI on GitHub Actions or GitLab CI and want a fast, opinionated flakiness dashboard without configuring a full observability stack.

Avoid this if

Your buyers expect enterprise-grade compliance, on-prem deployment, or deep integrations beyond GitHub Actions and GitLab CI in the first release.

Validate first

Ship a closed beta to twenty indie devs, ingest their public repo webhooks, and confirm that at least twelve return within seven days to view the top-three flaky tests view for their main repo.

Problem and target customer

Why this exists

Customer problem

Engineering teams lose hours each week chasing intermittent CI failures spread across GitHub Actions, GitLab CI, and other runners, with no single view of which tests are flaky, which branches are degrading, or which repos are regressing.

Who pays

Indie developers and small engineering teams running multiple repos on GitHub Actions or GitLab CI who need a lightweight observability layer without adopting a full enterprise DevOps platform.

Business model

Self-serve monthly subscription with a free tier for one repo and a paid workspace tier for unlimited repos, longer history retention, and team seats.

Editorial note

PipelineRadar turns scattered CI signals into a single repo health view that indie devs can scan in under a minute.

The top-three flaky tests leaderboard is the anchor feature: it answers the question every developer asks after a red build.

Branch trend charts make it obvious whether a repo is getting healthier or drifting toward more failures over time.

Product goal

Who it serves and what it must change

Target user
Indie developers and small engineering teams running GitHub Actions or GitLab CI across multiple repos.
Problem
CI failures are scattered across providers and branches, making it hard to spot flaky tests or repo-level regressions quickly.
Measurable outcome
At least twelve of twenty beta users return within seven days to view the top-three flaky tests for their main repo.

Business rules

  • A test is flagged flaky when its rolling seven-day pass rate is between 40% and 90% with at least five runs
  • Top-three flaky tests per repo are recomputed on every new build event
  • Branch trend chart aggregates builds by day over the last fourteen days
  • Webhook signatures are verified before any record is persisted
  • Workspace retention defaults to thirty days of build history

Architecture and data flow

Components, integrations, and controls

Lovable dashboard

Railway webhook receiver

Supabase Postgres

Supabase Postgres

Resend digest sender

Resend digest sender

GitHub and GitLab OAuth apps

GitHub and GitLab OAuth apps

Integrations

  • GitHub Actions webhooks
  • GitLab CI webhooks
  • GitHub OAuth
  • GitLab OAuth
  • Resend transactional email

Data flow

  1. CI provider sends webhook to Railway receiver
  2. Receiver verifies signature and normalizes payload
  3. Normalized build and test records are written to Supabase Postgres
  4. Flaky score job recomputes top-three per repo
  5. Lovable dashboard reads aggregated views for the user

Failure handling

  • Invalid webhook signatures are rejected with a 401 response
  • Supabase write failures trigger a retry queue in Railway
  • OAuth token refresh failures prompt the user to reconnect the repo
  • Missing data for a repo shows an explicit empty state, not a fake chart

Security

  • OAuth scopes limited to repo read and webhook management
  • Webhook signature verification on every request
  • Row-level workspace isolation in Supabase Postgres
  • No long-lived build artifact storage in MVP

Rate limits

  • GitHub webhook delivery is acknowledged within five seconds
  • Flaky score recomputation is throttled to one job per repo per minute
  • Digest email send rate is capped at one per workspace per week

Deliverables and acceptance

Definition of done for the MVP

Deliverables

  • Lovable dashboard with workspace, repo, leaderboard, and branch screens
  • Railway webhook receiver deployed and accepting GitHub and GitLab events
  • Supabase Postgres schema for workspaces, repos, builds, tests, and flaky scores
  • Weekly digest email template and scheduler
  • OAuth flow for GitHub and GitLab repo authorization

Acceptance criteria

  • Top-three flaky tests for a connected repo render in under sixty seconds after the first build event
  • Repo dashboard shows correct red or green status pills for the latest build on each branch
  • Branch trend chart displays daily failure counts for the last fourteen days
  • Invalid webhook signatures return 401 and never persist records
  • Weekly digest email is delivered to at least ninety-five percent of subscribed workspaces

Why this is sufficient

Lovable ships the terminal-inspired dashboard quickly, Supabase Postgres handles the relational build and test history, Railway runs the webhook receiver close to the source, Resend delivers weekly digests, and OAuth keeps repo authorization scoped to the minimum permissions needed.
