+
+We have just concluded [Launch Week 15 with so many new updates](https://supabase.com/launch-week), but no launch week is complete without a hackathon! The Supabase Launch Week 15 Hackathon begins now! Open your favorite IDE or AI agent and start building!
+
+As of the time of publishing this blog post, the hackathon has begun and will conclude on Sunday, July 27th, at 11:59 pm PT. You could win an extremely limited edition Supabase swag and add your name to the Supabase Hackathon Hall of Fame.
+
+For some inspiration, check out all the [winners from previous hackathons](https://supabase.com/blog/tags/hackathon).
+
+This is the perfect excuse to "Build in a weekend, scale to millions.” Since you retain all the rights to your submissions, you can use the hackathon as a launch pad for your new Startup ideas, side projects, or indie hacks.
+
+## Key Facts
+
+- You have 10 days to build a new o**pen-source** project using Supabase in some capacity
+  - Starting 10:00 am PT Friday, July 18th, 2025
+  - The submission deadline is 11:59 pm Sunday, midnight PT, July 27th, 2025
+- Enter as an individual or as a team of up to 4 people
+- Build whatever you want - a project, app, tool, or library. Anything.
+- 1-minute video containing the following:
+  - Name of the project
+  - Demonstration of the project
+  - How Supabase is used within the project
+- [Here is an example video](https://youtu.be/KaWJQzTTx5k). We do not assess the quality of the video itself. Remember to keep it concise.
+
+## Prizes
+
+There are 5 categories, and there will be prizes for:
+
+- Best overall project
+- Best use of AI
+- Most fun / best easter egg
+- Most technically impressive
+- Most visually pleasing
+
+There will be a winner and a runner-up prize for each category. Every team member on winning/runner-up teams gets a Supabase Launch Week swag kit, and the winner of the best overall project will get this cool mechanical keyboard as well!
+
+## Submission
+
+You should submit your project from the submission form before 11:59 pm Sunday midnight PT, July 27th, 2025. The submission form will be put up here on this article before the deadline. Come back in about a week to find it!
+
+## Judges
+
+The Supabase team will judge the winners for each category.
+We will be looking for:
+
+- Creativity/inventiveness
+- Functions correctly/smoothly
+- Visually pleasing
+- Technically impressive
+- Use of Supabase features
+- FUN! 😃
+
+## Rules
+
+- Team size 1-4 (all team members on winning teams will receive a prize)
+- You cannot be on multiple teams
+- One submission per team
+- It's not a requirement to use AI
+- All design elements, code, etc., for your project must be created **during** the event
+  - Using frameworks/ libraries is fine
+- All entries must be Open Source (link to source code required in entry)
+- Must use Supabase in some capacity
+- Can be any language or framework
+- You must submit before the deadline (no late entries)
+- Include a link to a 1-minute demo video
+
+## Additional Info
+
+- Any intellectual property developed during the hackathon will belong to the team that developed it. We expect that each team will have an agreement between themselves regarding the IP, but this is not required.
+- By making a submission, you grant Supabase permission to use screenshots, code snippets, and/or links to your project or content of your README on our Twitter, blog, website, email updates, and in the Supabase discord server. Supabase does not make any claims over your IP.

+
+We're very excited to announce [Supabase Storage](/storage) is getting better for everyone. We are:
+
+- Increasing the maximum file size to 500 GB, up from 50 GB
+- Reducing egress costs for requests cached by our API Gateway is charged at $0.03/GB, down from $0.09/GB
+- Free plans get 5 GB of cached egress in addition to 5 GB of uncached egress. All paid plans get 250 GB of cached egress and 250 GB of uncached egress, bundled in.
+
+The 500 GB limit for individual files is available for all paid plans starting next week. Lower cached egress pricing and increased quotas for cached egress will be rolling out gradually to all users over the next few weeks and will take effect at the end of your current billing cycle. This should be a price reduction for all users for Storage.
+
+## 10x Larger Uploads
+
+Our community has asked for better support for increasingly large files, from high resolution video platforms and media heavy applications to SaaS platforms handling user generated data, storing 3D models and data archival.
+
+We have made several optimizations to our platform infrastructure and API gateway to ensure reliable handling of very large files, allowing us to increase the limit from 50 GB to 500 GB for all paid plans.
+
+Once it's released next week, you can take advantage of this feature by setting the new upload size limit [here](/dashboard/project/_/settings/storage) and use the new storage-specific hostname for your uploads. You can do this by adding `storage` after your project ref in the standard Supabase url. Replace `project-ref.supabase.co` with `project-ref.storage.supabase.co`. The older URL format will continue to work.
+
+For uploading large files, we recommend using one of our multipart upload options:
+
+- [**Resumable uploads using TUS**](/docs/guides/storage/uploads/resumable-uploads) - Perfect for cases where network interruptions might occur, allowing uploads to resume from where they left off
+- [**S3 protocol multipart uploads**](/docs/guides/storage/uploads/s3-uploads) - Ideal for applications that need S3-compatible upload workflows
+
+Both approaches automatically handle breaking large files into manageable chunks during upload while presenting them as single objects for download.
+
+## 3x Cheaper Cached Egress
+
+All Supabase traffic flows through our API Gateway, which also functions as a content delivery network (CDN). When an asset is cached at the edge (and frequently accessed storage objects typically are), the CDN delivers it immediately. If it isn't cached, the request is forwarded to the region hosting your Supabase project before returning to the user.
+
+Initially, we leaned towards keeping our pricing model simple instead of reflecting regional and cache-status variations in egress costs. This unfortunately meant that customers with very high cached storage bandwidth couldn't benefit from our lower cached egress rates.
+

+  }}
+  alt="Uncached Egress"
+/>
+
+Today, we are introducing a new pricing line item and are able to offer cached egress at a much lower rate of $0.03/GB. Combined with the [Smart CDN for storage](/docs/guides/storage/cdn/smart-cdn), which increases the cache hit rate for storage significantly, this would significantly reduce egress bill for our largest storage users.
+
+## 2x Egress Quota
+
+Paid plans previously included 250 GB of unified egress. We've now split that into 250 GB of cached egress and 250 GB of uncached egress, so customers with high cache hit rates effectively get twice the free egress. Free plans now include 5 GB of cached egress alongside 5 GB of uncached egress.
+
+## What Will You Build?
+
+Check out [Analytics Buckets](/blog/analytics-buckets), the other Storage launch this launch week, and how we built persistent file storage for edge functions with Storage here.
