Best Bug Fixing Software

New Relic is a cloud based observability platform that unifies infrastructure monitoring, application performance monitoring, error tracking, log management, and distributed tracing in a single dashboard. All telemetry data is stored in a proprietary database called NRDB and queried with NRQL, a SQL like language built for observability data. The platform serves engineering teams that need to correlate metrics, events, logs, and traces to find the root cause of production issues quickly.

New Relic offers a permanent free tier with 100GB of monthly data ingest and one full platform user, alongside paid Standard, Pro, and Enterprise editions priced per user with additional data charged per gigabyte. Over 800 pre built integrations connect New Relic to popular cloud providers, container platforms, and alerting tools, and an AI powered engine helps predict and diagnose issues before they affect customers.

Rollbar is a cloud based error tracking and monitoring platform that captures errors, exceptions, and crash reports from applications in real time. It automatically groups related errors using machine learning, provides stack traces and breadcrumb telemetry for root cause analysis, and offers session replay to see what a user did before an error occurred.

Rollbar's paid tiers add features like Rollbar Analyze query language, adaptive alerting, and SAML/SCIM provisioning for larger teams. It also includes an AI agent called Resolve that can review code and open pull requests with suggested fixes. Pricing scales with monthly event volume, session replays, and AI credits, with a free tier for small projects and custom Enterprise pricing for high volume needs.

Bugfender is a remote logging platform that captures logs, crashes, and user feedback from every device running an app, even when issues do not cause a crash. Logs continue to be collected while a device is offline and sync once connectivity returns, and the web console organizes logs by session, device, and app version so developers can reproduce and diagnose bugs from real user devices rather than relying only on local testing.

SDKs are available for iOS, Android, React Native, React, and Angular, with installation taking a few minutes. Bugfender moved to monthly usage-based plans in late 2025, offering a free tier for small teams and paid tiers with longer retention, log archiving, and enterprise features like SSO and SLAs for larger organizations.

Bugsnag is a stability and error monitoring platform owned by SmartBear, now officially rebranded as SmartBear Insight Hub while still operating at the bugsnag.com domain. It automatically captures errors and crashes across more than 50 platforms, groups them by root cause, and prioritizes issues by severity and business impact using stack traces, breadcrumbs, and device or user context.

Beyond error monitoring, the platform has expanded into real user monitoring, backend performance monitoring, and distributed tracing for full-stack observability. Paid Select and Preferred tiers scale with monthly error events and performance spans, adding features like automatic error assignment, feature flags, SSO provisioning, and both SaaS and on-premises deployment options for larger teams.

GlitchTip is an open source error tracking platform built with Django and Vue.js, designed as a lighter alternative to self-hosted Sentry while remaining compatible with Sentry's client SDKs. It captures crash reports with stack traces, groups errors, tracks releases and environments, and adds uptime monitoring and basic performance transaction tracking, all under the MIT license.

Because it reuses existing Sentry SDKs and the same DSN format, teams can point their current error-tracking integrations at GlitchTip with minimal changes. It runs in as little as 512MB of RAM, making self-hosting practical for small teams, while a hosted cloud service with tiered event-based pricing is available for teams that prefer not to manage infrastructure themselves.

TrackJS is a frontend focused JavaScript error monitoring tool that automatically captures unhandled errors, rejected promises, failing network calls, and console errors from web applications. Its Telemetry Timeline reconstructs the network requests, user interactions, and console logs that happened before an error, giving developers the context needed to reproduce and fix issues without guesswork. An AI Debugger analyzes this telemetry alongside source code to explain what went wrong.

TrackJS pricing scales with monthly page views rather than error counts, starting at $49 a month for the Starter plan covering 100,000 page views and rising to $199 a month for the Business plan covering up to 100 million page views. All plans include unlimited users and unlimited server side ignore rules, and discounted pricing is available for bootstrapped and charity organizations.

Devin AI is an autonomous AI software engineer that helps engineering teams plan, write, test, and ship code across complex codebases. It is designed for developers, technical leads, and enterprise teams and is especially useful for large-scale code migrations, refactors, PR review, bug fixing, documentation, and incident triage. Unlike simpler code assistants, it can work across repositories, use tools like GitHub, Slack, Linear, and Datadog, and keep humans in the loop for review and approval. It offers flexible product options including Devin Cloud, Devin Desktop, Devin CLI, Devin Review, and a Windows VM, making it a strong fit for organizations modernizing legacy systems or scaling repetitive engineering work with measurable time savings.
