Self-host
One-click deploy
Import compose from GitHub or hit Deploy to Render. Same two containers as a VPS: ghcr.io/epure-sh/epure plus PostgreSQL 16. No marketplace export required.
Epure
SDK
Keep the Sentry SDK
Already ship @sentry/browser, @sentry/nextjs, or sentry-python? Paste a new DSN. GlitchTip, Bugsink, Telebugs, Better Stack Errors, and Epure accept it. Honeybadger does not. Compatible means exception ingest, not full Sentry parity.

Product
Lightweight self-hosted
Predictable self-hosted exceptions: Sentry SDK wire, Spike Valve, agent triage — two Compose services you can operate.
Epure
Product
Error tracking for startups
Predictable exceptions for 2–15 person teams: Sentry SDK wire, Spike Valve, agent triage, flat tiers when you want managed.
Epure
Proof
Resource footprint
Optional hardware proof for procurement — canonical docker stats. Product positioning leads with predictable ingest and triage, not MiB.
Epure
Self-host
Best self-hosted error tracking
Install shortlist for a VPS. Matrix on /research. MiB on /proof. Rank by license, containers, and DSN swap.
Epure
Pricing
Cheapest error tracking
Three invoices. A metered Sentry team plan, a $0 license on a VPS you operate, or published Cloud list prices (Cloud not live).
Epure
License
Open-source error tracking
License first. What counsel signs for a self-hosted error tracker that still takes a Sentry DSN.
Epure
Pricing
Sentry bill jumped
A crash loop and tracing left on turn a quiet Team plan into a spike invoice. What to cut first.
Epure
Indie
Indie hacker error tracking
Solo production apps: DSN swap, two containers, no overage meter when the deploy breaks.
Epure
Product
Production error tracking
A throw in production becomes one issue, a count, and a stack you can act on.
Epure
Decide
Error tracking vs APM vs replay
Which signal answers a 500, a slow hop, or a UI click path.
Epure
Research
Self-hosted research matrix
Canonical sourced comparison matrix. Shortlist essay and /vs pages stay linked.
Epure
Founder note
No observability platform
In an incident I open one exception, a count, and one stack. A usage-priced suite bills that spike and gives me a second system to run.
Epure
Decision
When tracking is enough
If your daily loop is a grouped exception and a readable stack, you do not need session replay or distributed tracing on the same box. Keep the official Sentry SDK, paste a new DSN, and run a two-container tracker.
Epure
Guides
Migrate from GlitchTip
Keep your Sentry SDK; point the DSN at Epure; Confirm with Verify. Stay on GlitchTip when MIT, Django ops, or maturity wins.
Epure
SDK
Next.js + Epure
Pin @sentry/nextjs@7.120.0, set SENTRY_DSN and NEXT_PUBLIC_SENTRY_DSN to the same Epure project, zero sample rates, Verify client/server/edge.
Epure
SDK
Go + Epure
Point official sentry-go at Epure, set TracesSampleRate to 0, always Flush before exit, Verify panics become Issues with raw frames.
Epure
SDK
FastAPI + Epure
Keep FastAPIIntegration, point dsn at Epure, zero traces/profiles rates. Docs install is unpinned; Python fixtures use store. Confirm with Verify.
Epure
Guides
Migrate to Epure
Keep official Sentry SDK init, replace only dsn, zero traces/replay/profile rates, Confirm with Verify. No history import claim. Cutover checklist, not a compat matrix.
Epure
Self-hosting
VPS install + verify
Production install on a small VPS: ./configure --prod, deploy overlay, HTTPS proxy, GET /health, DSN then Verify. Commands-only; no RAM remake.
Epure
SDK
Envelope keep/drop
Epure keeps event items, discards transaction, skips replay/profile/session. Verify 202 then Issues; store vs envelope bisect; CORS and PUBLIC_URL rows.
Epure
Benchmark
Sentry self-hosted RAM
Official self-hosted Sentry cites about 16 GB RAM for the full suite. Epure idle receipts: about 53 MiB on a 2026-09-23 Linux VPS, about 82 MiB on 2026-09-12 Docker Desktop. Method, COMPOSE_PROFILES=errors-only disclosure, and how to re-measure.
Epure
SDK
Sourcemaps verify
Upload JS/TS .map files with DSN auth, match the SDK release string, demangle stacks in-process. 2 MB cap. No Symbolicator.
Epure
Self-host
Two containers
Docker Compose with exactly two services: a Rust ingest binary and PostgreSQL 16. No Redis, no Kafka, no worker fleet. Keep the official Sentry SDK and swap the DSN.
Epure
Ops
Spike valve flood
Self-hosted error flood soft sample: still HTTP 202 with a counter bump and body drop, then 403 ingest_cap_exceeded at the hourly project cap.
Epure
Alternatives
Sentry alternatives
Leave Sentry Cloud or a 16 GB self-host when you need grouped exceptions, not the full suite.
Epure
Self-host
Self-host under 512 MB
Documented RAM floor and container count decide what a 512 MB box can run. Self-hosted Sentry publishes 16 GB RAM plus 16 GB swap. Dated Epure idle receipts sit near 53 MiB on a VPS and 82 MiB on Desktop.
Epure
Free
Best free error tracking
Free splits two ways. SaaS free tiers cap events. Self-host $0 licenses leave you paying the VPS. Sentry Developer is one user; confirm the live error quota.
