5 Free Google Optimize Alternatives in 2026 That Are Actually Free
Quick answer
Google Optimize shut down on September 30, 2023. In 2026, only five A/B testing platforms offer genuinely free ongoing plans — not just trials. For non-technical marketing teams, Mida is the best free alternative with a Sandbox plan up to 100,000 Monthly Tested Users, native GA4 integration, a visual editor, and a 15KB compressed script. For engineering-led teams, GrowthBook is free and open source if you self-host. Omniconvert, ABlyft, and Amplitude Experiment also offer free starter plans with specific feature limits. Tools like VWO, Convert.com, and Crazy Egg no longer have ongoing free plans. VWO's former free starter plan was capped at 50,000 MTU and has been discontinued.
Key takeaways
- Only five platforms — Mida, GrowthBook, Omniconvert, ABlyft, and Amplitude Experiment — offer ongoing free plans in 2026. Most "free alternative" lists include tools that only have trials.
- Mida's free Sandbox is the most generous ongoing free tier among visual-editor tools: 100,000 MTU per month with no credit card and no forced upgrade.
- GrowthBook is free and open source for self-hosted deployments, but requires engineering capacity and has no visual editor in the self-hosted version.
- Omniconvert, ABlyft, and Amplitude Experiment offer free starter plans with feature or traffic limits that may suit very small teams.
- VWO discontinued its free plan. VWO's former free starter plan was capped at 50,000 MTU and has been discontinued. Convert.com, Crazy Egg, and most other alternatives only offer time-limited trials.
Google Optimize and Optimize 360 shut down on September 30, 2023. For many teams, it was the only A/B testing tool they had ever used — free, connected to GA4, and simple enough that marketers could launch tests without engineering support.
Since then, most "free Google Optimize alternative" articles have become misleading. They list tools like VWO, Convert.com, and Crazy Egg as "free" when those platforms only offer time-limited trials, not ongoing free plans. VWO discontinued its free starter plan. Convert.com offers a 15-day trial. Crazy Egg offers a 30-day trial. None of these are free alternatives.
This guide is different. It only covers platforms with ongoing free plans — tools you can use indefinitely without paying. In 2026, that list is short: five platforms. This article compares each one honestly, explains what you actually get for free, and helps you choose based on your team's technical capacity, traffic, and platform.
Free Google Optimize alternatives compared
| Tool | Free tier | Visual editor | GA4 integration | Best for | Paid starting price |
|---|---|---|---|---|---|
| Mida | 100,000 MTU/mo forever | Yes | Native, no setup | Non-technical teams replacing Optimize | $299/mo (annual) |
| GrowthBook | Unlimited (self-hosted) | Cloud plan only | Custom event setup | Engineering-led teams | Free (self-hosted) |
| Omniconvert | Free starter plan | Yes | Available | Ecommerce teams starting out | ~$350/mo |
| ABlyft | Free starter plan | Yes | Available | Privacy-focused technical teams | Contact sales |
| Amplitude Experiment | Free starter plan | Limited | Available | Amplitude analytics users | ~$1,061/mo |
Prices are approximate and subject to change. Always confirm current pricing on each vendor's website. "Free starter plan" typically means an ongoing free tier with traffic, feature, or seat limits.
The honest truth: your free options are limited
Google could afford to give Optimize away for free because it deepened lock-in with Google Analytics and Google Ads. Independent vendors do not have that incentive. After the Optimize sunset, most competitors used the influx of displaced users as a paid acquisition opportunity, not a reason to launch generous free tiers.
The result is that in 2026, only five platforms offer ongoing free plans. Every other alternative — including the ones most commonly mentioned in "free alternative" roundups — requires payment after a trial period. If you are looking for a free replacement, your shortlist should start and end with the five tools above.
Free A/B Testing Tool
Run your next A/B test the right way
Visual editor, 15 KB script, GA4-native — and free forever up to 100,000 monthly visitors. No developer required.
1. Mida
Mida is the closest functional replacement for Google Optimize among the free options. It is the only tool on this list that combines a visual editor, native GA4 integration, and a permanently free tier with no credit card required.
What you get on the free Sandbox plan:
- Up to 100,000 Monthly Tested Users per month
- Visual editor for no-code variant creation
- Code editor for custom CSS and JavaScript
- Native GA4 integration — no custom setup
- A/B testing, URL redirect testing, and personalization
- Anti-flicker script loading
- No forced upgrade timeline
Where Mida goes beyond Optimize:
- MidaGX: Generate test variants from plain-language prompts
- SPA support: Built-in triggers for React, Next.js, Vue, and Angular
- No-code live deployment: Publish winning variants without a code release
- Usage-based pricing: When you upgrade, pay only for visitors who enter experiments
Performance: Mida's script is 15KB compressed and loads in approximately 20ms. For teams that relied on Optimize because it was invisible to page performance, this matters. We have also published an A/B testing tool speed benchmark comparing script sizes across the category.
Paid plan: Growth starts at $399/mo month-to-month or $299/mo billed annually.
Choose Mida when:
- You want the most direct free replacement for Google Optimize's workflow.
- You need a visual editor and do not have engineering support.
- You use GA4 and want native integration without custom setup.
- You care about site speed and Core Web Vitals.
Avoid Mida when:
- You need full product analytics, data warehouse metric layers, or enterprise feature flag suites.
- Your main experimentation surface is native mobile apps or backend-only logic.
2. GrowthBook
GrowthBook is the strongest free option for engineering-led teams. It is open source under Apache 2.0 and free to self-host indefinitely.
What you get for free:
- Unlimited self-hosted experimentation
- Feature flags with percentage rollouts and targeting
- Warehouse-native analysis (BigQuery, Snowflake, Redshift, Databricks)
- SDKs for most major languages
- Bayesian and Frequentist statistics
The catch: The self-hosted version has no visual editor. Marketers cannot create tests without developer support. Setup requires engineering time for infrastructure, SDK integration, and maintenance. A visual editor is available on GrowthBook's Cloud plan, but that is not free.
Paid plan: Cloud plans are available for teams that want a managed version with visual editing.
Choose GrowthBook when:
- Your team wants open-source experimentation or self-hosting.
- Engineers are comfortable implementing feature flags and experiments in code.
- You want to connect analysis to your existing data warehouse.
Avoid GrowthBook when:
- Marketers need to launch visual website tests without developer support.
- You do not have engineering capacity to own implementation and maintenance.
3. Omniconvert
Omniconvert offers a free starter plan alongside its paid ecommerce optimization platform. It includes A/B testing, split URL testing, surveys, and segmentation.
What you get on the free starter plan:
- Limited traffic volume (check current limits on Omniconvert's pricing page)
- A/B and split URL testing with a visual editor
- Surveys and polls
- Basic segmentation
- Heatmaps and session recordings
The catch: The free plan has traffic limits that may be too restrictive for growing sites. Advanced features like revenue tracking, customer lifetime value analytics, and extensive segmentation require a paid plan.
Paid plan: Starts at approximately $350/mo for 100,000 tested users.
Choose Omniconvert when:
- You run ecommerce experiments and want surveys in the same platform.
- You want testing plus behavior and funnel tools at SMB-friendly pricing.
- Your traffic fits within the free starter limits.
Avoid Omniconvert when:
- You only need fast, lightweight client-side A/B testing without the extra tools.
- Your traffic exceeds free starter limits quickly.
4. ABlyft
ABlyft is a privacy-first experimentation platform with a free starter plan. It is especially relevant for EU-based companies and teams that want controlled client-side testing.
What you get on the free starter plan:
- Limited traffic volume and experiment count
- Privacy-first architecture with no individual visitor tracking
- Github integration and debug mode
- Visual and code editors
- Mutual experiment exclusion
The catch: The free starter has traffic and experiment limits. Like Omniconvert, it is designed to let small teams validate the platform before upgrading. ABlyft also requires more technical setup than marketer-first tools like Mida.
Paid plan: Contact sales for pricing.
Choose ABlyft when:
- Privacy and GDPR-friendly positioning are important.
- You want a focused A/B testing platform rather than a behavior analytics suite.
- Your experimentation team is comfortable with technical setup.
Avoid ABlyft when:
- You need the most marketer-friendly visual workflow for non-technical users.
- You require transparent self-serve pricing.
Free A/B Testing Tool
Run your next A/B test the right way
Visual editor, 15 KB script, GA4-native — and free forever up to 100,000 monthly visitors. No developer required.
5. Amplitude Experiment
Amplitude Experiment offers a free starter plan, but it is only practical if your team already uses Amplitude for product analytics.
What you get on the free starter plan:
- Limited experiment volume for Amplitude users
- Experiments tied to Amplitude behavioral cohorts and funnels
- Feature flags with targeting rules
- Cross-platform identity resolution
The catch: The free starter is only available within the Amplitude ecosystem. If you do not already use Amplitude as your analytics foundation, this is not a practical standalone replacement for Google Optimize. The visual editor is also limited compared to dedicated website testing tools.
Paid plan: Starts at approximately $1,061/mo for 100,000 tested users.
Choose Amplitude Experiment when:
- Your company already uses Amplitude deeply for product analytics.
- You want experiments tied to cohorts, funnels, and retention metrics.
- Your tests are mostly product experiments rather than public website edits.
Avoid Amplitude Experiment when:
- You do not use Amplitude as your analytics foundation.
- Your team needs a lightweight visual editor for public website experiments.
Tools that are not actually free
Most articles about "free Google Optimize alternatives" include tools that only offer time-limited trials. For clarity, here is the status of commonly mentioned tools as of early 2026:
- VWO: Discontinued its free plan. Only a 30-day trial remains.
- Convert.com: 15-day trial. No ongoing free plan.
- Crazy Egg: 30-day trial. No ongoing free plan.
- Optimizely: No free plan or trial. Contact sales only.
- AB Tasty: No free plan. Contact sales only.
- Kameleoon: No free plan. Contact sales only.
- Adobe Target: No free plan. Contact sales only.
If you need a free tool, your realistic options are the five platforms covered above. If you have budget for a paid tool, see our broader guide to the best A/B testing tools in 2026 for a comparison of 17 platforms across all price points.
How to choose the right free alternative
Use this decision tree:
- If you need a visual editor and have no engineering support: Choose Mida. It is the only free tool with a visual editor, native GA4 integration, and a generous traffic allowance.
- If you have engineering support and want open source: Choose GrowthBook. It is free forever if you self-host, but requires technical setup and has no visual editor.
- If you run ecommerce and want surveys + testing: Compare Omniconvert and Mida. Check whether Omniconvert's free starter traffic limits fit your store.
- If privacy and GDPR are top priorities: Compare ABlyft and Mida. ABlyft has stronger privacy positioning but a more technical workflow.
- If you already use Amplitude: Check whether Amplitude Experiment's free starter covers your experiment volume.
Migrating from Google Optimize: a short checklist
- Export historical data — You cannot retrieve Optimize data after shutdown. If you missed this window, skip to step 2.
- Audit your active experiments — Document what you were testing, the hypothesis, and the target pages.
- Choose your replacement — Use the decision tree above. Do not panic-buy an enterprise tool if your program is not operationally ready.
- Install the new snippet — Place it as high in
<head>as possible. Avoid loading it through GTM to prevent flicker. - Reconnect GA4 — Mida does this natively. For other tools, configure the Measurement Protocol or custom events.
- Rebuild your first test — Start with a high-impact, low-complexity test (hero headline, CTA button) to validate the setup.
- Set a 90-day review — Evaluate whether the tool is actually being used. The most expensive platform is the one that runs zero tests.

FAQs
Q: What is the best free alternative to Google Optimize in 2026?For non-technical marketing teams, Mida is the best free alternative. Its Sandbox plan covers up to 100,000 Monthly Tested Users per month forever, includes a visual editor, and integrates natively with GA4. For engineering-led teams, GrowthBook is free and open source if you self-host. Omniconvert and ABlyft also offer free starter plans with traffic limits.
Q: Is VWO still free?No. VWO discontinued its free starter plan. It now only offers a 30-day free trial, after which a paid plan is required. When VWO had a free plan, it was capped at 50,000 monthly tested users. That tier no longer exists.
Q: Is Convert.com free?No. Convert.com offers a 15-day free trial with no credit card required, but there is no ongoing free plan. After the trial, paid plans start at $299 per month when billed annually.
Q: Is there a 100% free replacement with a visual editor?Mida is the only visual-editor tool with a permanent free tier that does not require a trial conversion. Omniconvert and ABlyft offer free starter plans with visual editors but have traffic or feature limits. GrowthBook and Amplitude Experiment do not offer visual editing on their free tiers.
Q: Does GA4 have a built-in A/B testing tool?No. GA4 does not include A/B testing. Google's recommended path is to use third-party experimentation platforms that integrate with GA4, which places the testing functionality into a paid tool while keeping GA4 as the analytics layer. Mida integrates natively with GA4 on its free plan.
Q: Will my historical Google Optimize data ever be accessible again?No. Google Optimize data is permanently gone. Any historical experiment data that was not exported before September 30, 2023 is not retrievable.
Q: What happened to Google Optimize?Google Optimize was sunset in September 2023. Google has not replaced it with a native tool. Teams that relied on Google Optimize — especially for free website A/B testing with GA4 integration — have moved to platforms like Mida, GrowthBook, and Omniconvert. Mida specifically offers a free Sandbox plan up to 100,000 MTU and a native GA4 integration, making it the most direct functional replacement for teams that valued the Google Optimize workflow.
Q: How much traffic do I need to run an A/B test?There is no single answer, but as a practical rule: running a test with fewer than 1,000 conversions per variant makes it very hard to reach statistical significance on most conversion rate improvements. The minimum sample size depends on your current baseline conversion rate, the size of the lift you want to detect, and your desired confidence level. Use a sample size calculator before starting. Mida's free 100,000 MTU allowance covers most small-to-mid-size sites indefinitely.
Q: What is a Monthly Tested User (MTU)?A Monthly Tested User is a unique visitor who enters at least one active experiment in a billing month. This is the pricing metric used by Mida, Convert Experiences, VWO, and several other platforms. It is different from total monthly visitors: if your site receives 500,000 visitors per month but only one page has an active experiment that 80,000 visitors see, your MTU count is approximately 80,000. MTU-based pricing is generally more predictable than page view pricing. See our visual guide to Monthly Tested Users.
Q: Can I use Mida for free forever?Yes. Mida's Sandbox plan is free forever up to 100,000 Monthly Tested Users per month. It includes the visual editor, code editor, GA4 integration, A/B testing, URL redirect testing, and personalization. There is no credit card required and no forced upgrade timeline. If your traffic grows beyond 100,000 MTU, you can upgrade to the Growth plan at $299 per month when billed annually.
Conclusion
In 2026, the list of genuinely free Google Optimize alternatives is short: Mida, GrowthBook, Omniconvert, ABlyft, and Amplitude Experiment. Most other tools mentioned in "free alternative" articles only offer time-limited trials.
For most teams, Mida is the most practical free replacement. It is the only tool that combines a visual editor, native GA4 integration, and a permanently free tier with no credit card required. If you have engineering capacity and want open-source self-hosting, GrowthBook is a strong alternative. If you are already in the Amplitude ecosystem, check their free starter plan. For ecommerce teams with very low traffic, Omniconvert's free starter may also be worth evaluating.
The most expensive mistake is not the tool you choose — it is the quarter you spend without a working testing program while evaluating options. If you are unsure, start with Mida's free Sandbox. It costs nothing to validate whether the workflow fits your team.
