Expiry
No expiry - free forever. No renewal needed.
Gotchas
AGPL-3.0 (not Apache 2.0 since Nov 2023): if you modify and offer it as a service, source-disclosure obligations can apply; unmodified self-hosted use is fine. You run your own HA/storage - ops cost is on you. Enterprise features (SSO, RBAC, federated search, QoS, audit) are not in the OSS build - those come via the free 50GB/day Enterprise self-hosted tier below.
Self-Hosted Enterprise Free Tier (50 GB/day) high confidence
Enterprise Edition (SSO, RBAC, federated search, query management, workload QoS, audit trail, sensitive-data redaction) is free up to 50 GB/day (~1.5 TB/month) of ingestion per legal entity, with no license key required, and includes full commercial use. This is a genuine free-forever tier, not a trial.
Eligibility
Any legal entity (B2B license; personal/household use excluded). No funding cap, no .edu requirement, no credit card, no region limit. Aggregated across all deployments of the same legal entity.
How to claim
Download the O2 Enterprise build from https://openobserve.ai/downloads/ (v1.1.x, all OSes) and run it - it works without requesting a license up to 50 GB/day. No sign-up or license key needed for the free tier. Above 50 GB/day you must request a paid license via sales.
Expiry
Indefinite; no stated sunset date. Free-tier allowance is part of the EULA (last updated 2026-09-05), not a time-boxed promotion.
Gotchas
Spike buffer: you may exceed 50 GB/day up to 3 times per month; after the 3rd excess, search queries are BLOCKED until volume drops back under the limit or you buy a license. 'Daily Ingestion' is counted uncompressed, per 24h UTC day. EULA is B2B-only - a student's side-project company is fine, but purely personal/household use is out of scope. Monitoring/usage telemetry is enabled under the EULA.
OpenObserve Cloud 14-day free trial (no credit card) high confidence
14-day trial on the Pay-As-You-Go (Professional) cloud plan: $0.50/GB ingested + $0.01/GB queried, unlimited users, logs/metrics/traces/RUM/session replay; included retention: metrics 15 months, logs/traces/RUM 30 days. No credit card required to start (pricing page + ToS Free Trial section). Available in 4 regions (US-West-2 Azure, US-East-2 AWS, EU Central AWS, AP South 1 AWS).
Eligibility
Anyone creating a new Cloud org - students/startups alike; no .edu requirement, no CC required to begin. No region restriction beyond the 4 offered cloud regions. Signup: https://cloud.openobserve.ai/web/login?mode=signup
How to claim
1) Sign up at cloud.openobserve.ai 2) Create org - 14-day trial starts automatically (code defaults trial_ends_at to 14 days) 3) Ingest/query trial features free 4) Add a payment method to continue - after 14 days the org's ingestion/search/alerts/billing endpoints return 403 until you move to Pay-As-You-Go.
Expiry
Trial ends after 14 days; no extension stated; after expiry you must switch to usage-based billing (or terminate). No CC required before trial ends.
Gotchas
This is a TRIAL, not a free tier - the cloud free tier no longer exists (killed 2025-06-02, see sunset notes). At trial end you're billed $0.50/GB ingested + $0.01/GB queried for everything ingested during the trial usage model; extra non-metrics retention is $0.02/GB per additional 30-day period. Synthetic/uptime monitoring is still beta; RUM and error tracking carry separate per-unit fees in the underlying pay-as-you-go model.
AI features: 20 free credits in preview (AI SRE Agent + AI Assistant) medium confidence
AI-powered features (Incident Management / AI SRE Agent and AI Assistant) are free during preview; each account gets 20 credits, consumed per AI operation.
Eligibility
Any Cloud account (per pricing.md); no .edu or startup requirement; credits are per account. No stated region limit.
How to claim
Create any OpenObserve Cloud account (or use the 14-day trial) and use AI SRE Agent / AI Assistant - 20 credits are preloaded; free while in preview.
Expiry
Tied to preview status - when preview ends, standard Enterprise add-on pricing applies; 20 credits are finite and do not renew automatically.
Gotchas
AI features are listed under the Enterprise feature set, so full production use may require Enterprise plan access; 'free during preview' can end without per-user advance notice. Credits are a play-quota, not a discount.
OpenObserve Startup Program (50% -> 25% Cloud discount, 12 months) high confidence
Sign a 1-year OpenObserve Cloud contract and pay 50% off for the first 6 months, 25% off for the next 6 months. Discount is contingent on the 1-year contract; no cash value; cannot be extended, transferred, or renewed; standard pricing applies automatically after the 12 months. Program may be modified/terminated on 30 days' notice.
Eligibility
ALL of: total funding raised < $10M; ARR <= $1M; anticipated ingest > 100 GB/day; actively VC-backed or in a recognized accelerator program. Global (no region limit). No .edu involvement - a company program, approval at OpenObserve's sole discretion, documentation may be requested. One application per company.
How to claim
Apply on the 'Apply Now' form at https://openobserve.ai/startup/ (be ready to confirm investor/accelerator backing; a company email on your own domain). On approval, sign the 1-year Cloud contract and the tiered discount applies from the approval date.
Expiry
Discount valid for 12 months from approval (6 x 50%, 6 x 25%); not renewable. Not free - it is a discount, useful when ingest >100GB/day (at $0.50/GB that's ~$1.5k+/mo list, so real dollar value).
Gotchas
This is NOT a free offer - minimum 100GB/day ingest requirement excludes most students and pre-revenue startups; the 1-year commitment is the cost. Resale/abuse triggers termination. After month 12, full price applies unless you terminate. Verify current terms before applying - program terms can change on 30 days' notice.
Education / non-profit 'special pricing' via sales (no published program) medium confidence
OpenObserve states: 'Discounts available for eligible startups, non-profits, and educational institutions' - applied through openobserve.ai/contact-sales. There is NO published education license, student tier, .edu requirement, or fixed discount amount anywhere on the official site; no dedicated /education page exists. The Enterprise EULA is explicitly B2B-only ('business, commercial, or organizational purposes only, not consumer for personal, family, or household use'), so a purely individual student gets no licensed free offer; students' realistic free path is the self-hosted OSS or 50GB/day Enterprise free tier, plus the 14-day cloud trial.
Eligibility
Institution-level (university, research lab, non-profit) via sales negotiation; criteria not published. No .edu-only free product found.
How to claim
Contact openobserve.ai/contact-sales describing the institution and use case; expect a custom quote/quote-level discount, not a self-serve free offer.
Expiry
No program, so no expiry; offers are ad-hoc quotes.
Gotchas
Because the EULA is B2B, even a favorable education quote likely binds an institution, not a student. Do not confuse this with a student free tier - none exists.
SUNSET: OpenObserve Cloud's free tier was DISCONTINUED effective 2025-06-02 (announcement: https://openobserve.ai/blog/june-25-pricing-policy-updates/). Moving to fully usage-based Pay-As-You-Go with no minimums; existing free-tier cloud customers got a 30-day exemption (until ~2025-07-02) and then required a valid credit card on file for usage charges. New customers instead get the 14-day no-CC trial. PR #6922 (merged 2025-07-10) confirms the code: orgs default to a 14-day trial and the free plan was removed from the billing UI. So any 'OpenObserve Cloud free tier' seen in pre-June-2025 articles is stale. PRICING CHANGE: ingestion price moved from $0.30/GB (June 2025) to $0.50/GB on the current Professional plan (pricing.md, updated 2026-09-04) - trial/usage costs are higher than 2025 docs suggest. ALSO: uptime/CDN front - OpenObserve has no CDN; uptime/synthetic monitoring (HTTP/TCP/TLS/SSH + Playwright browser checks) is in BETA in Cloud as of Aug 2026 with no separate free tier found, and RUM/session replay on cloud carry per-unit pay-as-you-go fees; nothing in the current material is a permanent free monitoring/uptime/CDN offer - the permanent-free value is entirely in the self-hosted OSS build and the 50GB/day self-hosted Enterprise free tier.
