Pointing things out over Zoom screenshare is highly time consuming ("click the 4th checkbox on the right", "click the handle and drag"), and trying to figure out what users are doing over a live chat or phone call typically leads to endlessly frustrating back-and-forths.
When COVID forced all of us into remote work, we found ourselves spending a lot of time in screensharing sessions. We were tired of choppy frame rates and blurry text, and realized that we could get around this by sharing the user\u2019s screen in a different way. Rather than video streaming, which is how it\u2019s usually done, we could send over diffs of their webpage\u2019s DOM representation and reapply those in the viewer\u2019s browser \u2013 this is similar to how virtual DOM frameworks like React work.
We first used this technique for an earlier project (https://news.ycombinator.com/item?id=23363250) that rendered React apps on the server (a Node equivalent of Phoenix LiveView). This reduces development complexity for web apps by completely eliminating the need for RPC layers (REST, GraphQL) \u2013 for instance, you'd be able to write to the database directly from your React component and share state across sessions with a single hook. It works by sending DOM updates from the server (e.g. insert a node, change an attribute) in response to input actions sent from the client (e.g. click a button, type a character).
This approach uses significantly less bandwidth compared to traditional\nscreen sharing solutions, and gives us a semantic understanding of the webpage (e.g. a button is sent over as a <button />, instead of a blob of bytes). As a result, we can selectively filter out sensitive content and allow viewers to scroll and type on the webpage without any perceived latency.
To solve our screen sharing problem, we initially built a Chrome extension that let users browse web pages collaboratively. During YC, we saw that our early adopters were primarily using this tool to walk through their own web apps with their customers, so we decided to refocus the product towards helping companies onboard and support their users.
Because we're focused on the real time use case, we only record the DOM when a session is being viewed. This means that no data is sent to our servers unless Cohere is actively being used. Additionally, we don\u2019t persist or retain any session data.

HN! I\u2019m Zach, from Coherence (https://www.withcoherence.com/). We\u2019re building software that provides an integrated way to write, preview, and deploy code from one simple configuration. Check out our explainer video here: https://www.youtube.com/watch?v=V2YHVx8QsLg and a high level demo here: https://www.loom.com/share/072c2afd1099496298f69ab21fdf2820
We started Coherence because we found technology teams spent 30-40% of their time yak shaving and writing glue code, instead of building products our customers love. We don\u2019t think every team should have to build their own internal development platform, so we\u2019re building the software we\u2019d want to buy. Following the example of other great products like Replit, our toolkit is based on integration across the stages of an app\u2019s lifecycle - from dev to production.
Coherence provides one integrated dashboard with cloud development environments, automatic CI/CD, and full-stack environments for each branch (as well as production), all with one simple configuration. A developer can write, test, review, and deploy code from one interface with best practices built in. Devs are intuitively navigated to their own cloud resources when needed, eliminating time spent searching consoles for every log, metric, or configuration setting you might need. We currently support containerized full-stack web apps on AWS and Google Cloud. Unlike the PaaS category defined by Heroku, our goal is to help teams leverage the platforms provided by the best cloud providers, keeping the benefits of running in your own cloud account: unlimited extensibility, cost savings, compliance with audit requirements, and freedom to easily exit our platform without an impact to your systems.
You can play around with a Coherence sandbox and get a taste of the developer experience at app.withcoherence.com/sandbox. If you like what you can see, you can also deploy an app into your AWS or GCP with one of our starter templates for a new project: app.withcoherence.com. We\u2019re happy to support onboarding on a call or via Slack and we\u2019d love to discuss what it would look like to migrate one of your existing apps to Coherence.
