Vestara logoVestara

    Production debugging, connected.

    Every failure
    leaves a trail.

    Vestara connects crashes, logs, replay context, RUM signals, runtime targets, and alerts into one clear failure trail, so developers can understand what broke without stitching tools together.

    ✓ Crashes, logs, replay, RUM, and alerts in one flow✓ Runtime and device context tied to each failure✓ Built for apps, web, and backend services

    Failure Trails

    Trace the whole failure story, not just the crash.

    Vestara connects crashes, API failures, breadcrumbs, logs, replay, and performance signals into one timeline. See what happened before, during, and after every production failure — no more context switching between tools.

    Web session replay

    Watch what the user did before the crash.

    Web session replays with privacy masking by default. Jump to the exact click, scroll, or network call that led to the failure. Mobile replay is on the roadmap.

    More capabilities

    Everything you need to debug production

    Alerts

    Slack and email alerts with delivery history. Get notified when crashes spike, errors cross thresholds, or a critical user hits a failure — without drowning in noise.

    Bring Your Own Database

    Connect your own Neon or Postgres-compatible database for more control over retention and data ownership.

    AI-assisted SDK setup

    Use a setup prompt with Cursor, Claude Code, Codex, or a compatible coding agent to install the SDK and wire up the first integration faster.

    WORKFLOW COMPARISON

    Your tools show the pieces. Vestara shows the failure story.

    Most teams already have crash reports, logs, replay, metrics, and alerts. The hard part is connecting those signals while production is broken.
