Alternatives

Sentry alternatives for mobile apps

Six options for React Native and mobile teams tired of seven separate meters.

Sentry is the best-known error monitoring platform for good reason. It is mature, it symbolicates properly, its tracing and replay products are strong, and it supports dozens of languages including whatever your backend is written in. If you need distributed tracing across services, this page ends by telling you to stay.

Mobile teams look elsewhere for two specific reasons. The first is billing: the headline plan covers errors only, and spans, replays, logs, cron monitors, uptime checks and profiling are each metered separately — as of July 2026, Sentry Team is $26/month billed annually for 50,000 errors, with overage around $0.00025–0.000315 per event and replays around $0.00375 each beyond the fifty included. Seven meters is difficult to forecast on a mobile release cycle where a bad build can multiply error volume overnight.

The second reason is scope. A stack trace tells you what broke and never what it cost. Sentry has no funnels, no retention and no install attribution, so "did this crash lose us signups" cannot be answered inside it. Six alternatives follow, two of which beat Sentry on mobile depth specifically.

Why teams look for a Sentry alternative

Seven meters, one invoice

Errors, spans, replays, logs, cron monitors, uptime checks and profiling each bill separately. Enabling a feature to investigate an incident quietly changes next month’s cost, and on mobile a single bad release can multiply error volume before you can ship a fix.

Frequency, not impact

Sentry can tell you an error fired four thousand times. It holds no conversion data, so it cannot tell you which of those four thousand cost you anything. Triage by count reliably promotes the noisy bug on your busiest screen over the quiet one killing checkout.

Silent failures are invisible

A tap wired to a handler that returns early, a form posting into the void, an endpoint answering 200 with an empty body. Nothing raises, so nothing reaches Sentry — while the user taps four times and uninstalls. No error monitor can see these, because there is no error.

How Nohmo detects them

Mobile is one platform among forty

Sentry’s breadth across languages is a genuine strength for a full-stack team and a dilution for a mobile one. Install attribution, release adoption and screen-level funnels are simply not part of the product, so mobile teams still buy two or three more tools.

The 6 best Sentry alternatives

Ranked for a product team, with the trade-offs stated in both directions. Where another tool beats ours, it is named and the reason is given.

Crashlytics

Pure mobile crash triage, free at any volume

If the goal is crash reporting and nothing else, Crashlytics is free, excellent, and the honest first recommendation for most mobile teams leaving Sentry on cost. Grouping is mature, native symbolication including NDK is thorough, and crash-free rates are reliable. It answers "did it crash" completely and answers nothing else at all.

Strengths

Free at any volume, with no meters to forecast
Deep native symbolication including Android NDK and C++ frames
Mature grouping heuristics and reliable crash-free rate reporting

Trade-offs

No product context — no funnels, retention or session journeys
Mobile only, so your web surface needs something else
Ties you further into the Firebase console and Google ecosystem

Nohmo vs Crashlytics — full comparison

Nohmo

Our pick

React Native teams who want the crash, the funnel and one flat bill

Captures the same class of errors — JavaScript exceptions, unhandled rejections, failed fetch and XHR requests, native iOS and Android crashes — and puts each next to the session that produced it. Ranks bugs by estimated revenue lost by comparing sessions that hit an error against sessions that reached the same page and did not. Product analytics, install attribution and release health are in the same SDK at $49/mo flat per project, with no per-event metering.

Strengths

One flat price with no meters — a bad release does not change the invoice
Bugs ranked by estimated revenue lost rather than by frequency
Detects silent failures — dead taps, void form submits, empty 200s — that raise no exception
Funnels, retention, install attribution and release health in the same SDK
One package for web and React Native, cookieless, with retroactive user linking

Trade-offs

No source map or dSYM symbolication yet — traces are raw, and materially less readable than Sentry’s
No distributed tracing or APM, and no session replay video
No Android NDK or C++ crash coverage, and no ANR detection
JavaScript, React, Next.js and React Native only — no backend-language SDKs

Nohmo vs Nohmo — full comparison

Bugsnag

Teams who want release stability as a hard gate

The closest like-for-like swap for Sentry’s error product without the surrounding meters. Stability scores and release-health gating are first-class, which suits a team shipping on a cadence that wants an objective bar for rolling a build forward. Narrower than Sentry by design, and easier to reason about as a result.

Strengths

Excellent stability scoring and release gating workflow
Strong mobile symbolication and grouping
Simpler billing than seven separate meters

Trade-offs

Still priced per event, so volume spikes still cost money
No product analytics or attribution
Smaller ecosystem and fewer integrations than Sentry

Instabug

Mobile teams who want user-reported bugs alongside caught ones

Mobile-first throughout, and the only pick here that treats the user as a source of signal. Shake-to-report, annotated screenshots and in-app feedback sit beside crash reporting, APM and network monitoring. If a real share of your bugs arrive through support rather than through a handler, this closes a gap the others leave open entirely.

Strengths

In-app bug reporting, screenshots and user feedback built in
Mobile-first APM and network diagnostics
Good session context attached to each report

Trade-offs

Priced per seat and per session; not cheap at scale
Product analytics is thin next to a dedicated tool
Mobile only

Embrace

Larger mobile teams chasing ANRs, startup time and rendering

The most mobile-specialised platform here and the one that beats Sentry on mobile depth. Complete session-level telemetry rather than sampled snapshots, ANR capture, startup and rendering performance, and network diagnostics at a level the general-purpose tools do not attempt. Priced and sold for teams with a dedicated mobile performance owner.

Strengths

Exceptional mobile depth — ANRs, startup traces, rendering, network
Full session telemetry, useful for issues that only reproduce on real devices
Purpose-built for mobile rather than adapted to it

Trade-offs

Enterprise pricing and a sales process to match
Considerable overkill for a small team
Mobile only, with no web story

Countly

Teams who cannot let crash payloads leave their infrastructure

Crash payloads routinely carry user identifiers, device detail and breadcrumb data, which for some teams makes a hosted vendor a non-starter regardless of features. Countly self-hosts, combines crash reporting with product analytics, and has an open-source core. The obligation is that you run it.

Strengths

Self-hostable — crash data stays on your own servers
Crash reporting and product analytics in one platform
Open-source core you can read and extend

Trade-offs

You carry the operational burden, upgrades included
Crash analysis is less refined than the specialists
The more useful plugins sit behind commercial tiers

When you should stay on Sentry

Migrations cost more than the invoice they save. These are the cases where the honest recommendation is to close this page.

•You need distributed tracing or APM across backend services. Nothing on this list is a substitute, and it is not close — Sentry Performance is a genuinely different class of product.
•You need session replay video rather than an event-level journey. Watching the user’s screen is not the same as reconstructing their steps, and when you need the former nothing else will do.
•Readable symbolicated stack traces are essential today. Sentry resolves minified JavaScript through source maps and mobile crashes through dSYM and ProGuard; Nohmo does not yet, and on mobile that difference is felt on every single trace.
•You need error tracking in a backend language — Python, Go, Ruby, PHP, Java. Sentry covers them all from one account, and running a separate tool per runtime is a worse outcome than a complicated invoice.

Switching from Sentry to Nohmo

Run both in parallel first. Two weeks of side-by-side data on your own traffic settles the question better than any comparison page, including this one.

Install alongside what you already have

Nohmo does not conflict with Sentry. It wraps fetch and XHR and adds its own global handlers without removing Sentry’s, so both keep reporting. Run them together through at least one release and compare what each catches on real devices.

bash

npm install nohmo

Replace two SDKs with one provider

Two initialisations collapse into one mount. From here the same tree yields errors, screen views, taps and complete journeys. Pass the build version through options.release so a jump in crash rate can be pinned to the release that caused it.

tsx

// Before — two SDKs, two configs
Sentry.init({ dsn: process.env.SENTRY_DSN })
analytics.init({ writeKey: process.env.SEGMENT_KEY })
 
// After — one provider
import { NohmoProvider } from 'nohmo/react-native'
 
<NohmoProvider
  projectId="proj_xxxx"
  apiKey="pk_xxxx"
  options={{ release: process.env.APP_VERSION }}
>
  <RootNavigator />
</NohmoProvider>

Delete most captureException calls

Uncaught exceptions, unhandled promise rejections and native crashes are captured automatically, so the majority of manual reporting can simply go. Where you want an explicit record with your own context, send is the equivalent.

tsx

// Before — Sentry
Sentry.captureException(err, { tags: { checkout: 'true' } })
 
// After — Nohmo (most of these can just be deleted)
const { send } = useNohmo()
send('JS_ERROR', { message: err.message, stack: err.stack, checkout: true })

Point your CI release step at Nohmo

Replace the Sentry release step so crash rates and metric movements correlate with deploys. The endpoint is idempotent on version and platform, so re-running a pipeline is safe.

bash

curl -X POST https://www.nohmo.in/api/tracker/release/ \
  -H "X-API-Key: $NOHMO_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"version":"2.4.1","platform":"ios","commitSha":"'"$GIT_SHA"'"}'

Give one goal a monetary value

This is the step that pays for the migration. Once a conversion carries an amount, Nohmo can compare sessions that hit an error against sessions that reached the same page and did not — and price the gap. That is the number that decides what you fix first.

tsx

const { trackConversion } = useNohmo()
 
trackConversion('user_created')
trackConversion('purchase', { amount: 29.99, currency: 'USD' })

Frequently asked questions

What is the best Sentry alternative for mobile apps?+

For free crash triage, Crashlytics. For release stability gating, Bugsnag. For in-app user feedback, Instabug. For deep mobile performance including ANRs and startup traces, Embrace — it beats Sentry on mobile depth. For a React Native team that wants the crash tied to the funnel step and ranked by revenue lost on one flat bill, Nohmo. If crash data cannot leave your infrastructure, Countly.

How much does Sentry actually cost?+

The headline is $26/month billed annually on Team, which buys 50,000 errors, 5M tracing spans, 50 replays and 5GB of logs. Business doubles down at $80/month. What makes it hard to budget for is that all seven of those things meter independently, so a busy month can add overage on several lines at once — 80,000 errors alone takes Team to roughly $36. Turning on profiling or replays during an incident quietly changes the following invoice. Figures from sentry.io/pricing, checked July 2026; check them yourself before deciding.

Is there a free Sentry alternative for mobile?+

Crashlytics is free at any volume and is the obvious answer for crash reporting alone. Sentry’s own developer tier covers 5,000 errors a month. Countly can be self-hosted for infrastructure cost. Nothing free matches Sentry’s breadth, and if budget is the binding constraint, Crashlytics plus a separate analytics tool is usually the cheapest workable combination.

Can Nohmo replace Sentry?+

If your surface is web plus React Native, usually yes: the same classes of failure are caught — thrown exceptions, rejected promises that nothing handles, fetch and XHR calls that fail, and native crashes on both mobile platforms. The honest exclusions are tracing, replay video, readable symbolicated traces, on-premise deployment, and anything running on a backend you also want monitored.

What does Sentry do better than Nohmo?+

On mobile specifically, three things stand out. Sentry uploads your dSYM and ProGuard mapping files at build time and resolves frames against them, so a crash arrives as named methods rather than hex addresses — every trace is affected by this, and it is the gap you will feel first. It catches ANRs and NDK-level native crashes, neither of which we handle. And it has session replay, distributed tracing, self-hosting and SDKs for every backend runtime you are likely to be paying for elsewhere.

What can Nohmo do that Sentry cannot?+

Three things. It ranks bugs by estimated revenue lost rather than frequency, using conversion data Sentry does not hold. It detects silent failures — dead taps, forms that submit into the void, successful responses with an empty body — none of which throw, so none of which appear in any error monitor. And it includes product analytics: funnels, retention, UTM attribution and mobile install attribution.

Can I run Nohmo and Sentry together?+

Yes, and it is the only evaluation worth trusting. Neither library evicts the other: Nohmo layers its handlers on top and leaves Sentry’s in place. Ship them together for one release and look at what each caught that the other missed — on your users’ devices, not on a table someone wrote to sell you something.

The verdict

Stay on Sentry if you need tracing, replay video, symbolicated traces or backend-language coverage — it is better at all four and pretending otherwise would not help you. Choose Crashlytics if crash triage is the whole job and it must be free, Embrace if mobile performance depth is the requirement, Instabug if users report your bugs. Choose Nohmo if you are a small React Native or web team paying separately for errors and analytics, want a bill that does not move with a bad release, and want to know which bug is actually costing you money.

Try Nohmo alongside Sentry

One npm package, one provider, and you are tracking analytics and errors — cookielessly. Nothing to remove while you evaluate.
